EU AI Act 2026: Credo AI vs Vanta vs Saidot and 5 More Tools (Verified August 2026)

EU AI Act enforcement changed on 2 August 2026, but the best tool is not the one with the longest control list. Credo AI is the strongest all-round governance system, Vanta is the cleaner choice for security-led teams already reusing compliance evidence, and the official EU checker is the right free first step. Six of the seven commercial products here still hide subscription pricing.

The short answer: which EU AI Act tool should you choose?

Choose Credo AI if you need one governance layer across models, vendors, policies, assessments, evidence, and runtime oversight. It has the best fit for a company with multiple business units or a mixed AI estate, where the hard problem is not filling in one checklist but keeping ownership and evidence coherent as systems change.

Choose Vanta if security or compliance already runs the buying process and your company uses Vanta for other frameworks. Its EU AI Act product contains more than 150 controls and 16 policies, and its strongest advantage is evidence reuse rather than unusually deep model testing.

Choose Saidot if you want an EU-native knowledge graph and collaborative workflow around systems, models, agents, datasets, risks, controls, and policies. Choose OneTrust when AI governance needs to sit beside an established privacy, data-governance, or GRC program. Choose IBM watsonx.governance when hybrid deployment, measurable model evaluations, or public usage pricing matters. Choose Holistic AI when technical testing and runtime policy enforcement are the center of the job.

Start with the EU AI Act Compliance Checker if you do not yet know your role or which obligations may apply. Add Trainual only when the missing layer is staff guidance, assigned training, acknowledgement, and exportable evidence under Article 4. Trainual is not an AI inventory, classification, conformity-assessment, or monitoring platform.

The choice flips on one question: where does your evidence already live? If it is spread across model teams and business units, Credo AI or Saidot gives it a governance home. If it already lives in a security-control program, Vanta is the shorter path. If it sits in OneTrust, keep the AI records beside the privacy and risk records. If the missing proof comes from model behaviour, not documents, compare IBM and Holistic AI. If you cannot answer which role applies, do not buy anything before using the official checker.

What changed on 2 August 2026?

The date matters, but not for the reason many old deadline charts suggest. 2 August 2026 was not the general start date for every high-risk AI duty. It was the start of Article 50 transparency rules and enforcement for provisions that already applied, including prohibited practices, AI-literacy measures, and obligations for providers of general-purpose AI models.

The official implementation timeline now separates six milestones:

• 2 February 2025: definitions, prohibited-practice rules, and AI-literacy provisions began to apply.
• 2 August 2025: obligations for providers of general-purpose AI models began to apply and the EU governance structure had to be established.
• 2 August 2026: Article 50 transparency rules began to apply, and national or EU enforcement started for applicable rules.
• 2 December 2026: the transition ends for certain synthetic-content systems placed on the market before 2 August 2026 to meet Article 50(2); additional prohibitions also begin.
• 2 December 2027: Annex III high-risk AI obligations begin under the amended timetable.
• 2 August 2028: obligations begin for high-risk AI embedded in products covered by Annex I.

The last two dates changed through Regulation (EU) 2026/1744, the Digital Omnibus amendment published in July 2026. A page that still calls 2 August 2026 the blanket high-risk compliance deadline is now stale.

What Article 50 means in practice

Article 50 is the transparency layer. Providers of systems that interact directly with people generally have to tell them they are dealing with AI unless that fact is obvious. Providers of systems that generate synthetic audio, images, video, or text must make covered outputs machine-readable and detectable as AI-generated or manipulated, within the provision's limits and exemptions.

Deployers have their own disclosures. They must inform people exposed to emotion-recognition or biometric-categorisation systems, and they must clearly disclose covered deepfakes and certain AI-generated public-interest text. The Commission's Article 50 guidance also says content created before 2 August 2026 does not need retroactive labelling.

For a support chatbot, the evidence might be a disclosure shown before the first reply, a product requirement linked to the deployed version, and a test record proving it renders in every supported interface. For a media generator, the evidence might include a machine-readable marking method, release tests, exception handling, and ownership for fixing failures. A policy PDF without implementation proof is the weakest part of that chain.

What Article 4 means for staff training

Article 4 requires providers and deployers to take measures supporting AI literacy among staff and other people using AI systems on their behalf. After the Digital Omnibus amendment, the law does not prescribe a particular or "sufficient" level. The Commission's current AI-literacy questions and answers say no certificate is required. An internal record of training and other guidance initiatives can be appropriate evidence.

That does not make a generic annual course enough for every role. A recruiter using a ranking system needs different guidance from an engineer integrating a general-purpose model or a marketer publishing synthetic media. The useful record connects the person, role, relevant system, assigned material, completion date, and current policy version. This is why Trainual appears in this guide, and why it ranks below products that can govern the systems themselves.

GPAI providers face a separate evidence burden

Providers of general-purpose AI models must maintain technical documentation, give downstream providers relevant information, implement a policy for EU copyright law, and publish a sufficiently detailed summary of training content. Models with systemic risk carry additional evaluation, risk-mitigation, incident-reporting, and cybersecurity duties. The Commission began full enforcement against GPAI providers, including the ability to impose fines, on 2 August 2026. Models placed on the market before 2 August 2025 have a legacy compliance deadline of 2 August 2027, according to the Commission's GPAI guidance.

Most companies buying the tools below are not training a frontier model. They are deployers using third-party models inside products or business processes. Their job is still substantial: identify the system, document its purpose and owners, determine the organisation's role, classify the risk, bind the right controls, gather provider evidence, train affected staff, monitor changes, and preserve a decision trail.

The penalty ceiling is high, but it is not the buying criterion

Under Article 99, prohibited practices can carry a maximum administrative fine of EUR 35 million or 7% of worldwide annual turnover for an undertaking, whichever is higher. Specified operator duties and Article 50 violations can reach EUR 15 million or 3%. Incorrect, incomplete, or misleading information supplied to a notified body or authority can reach EUR 7.5 million or 1%. For SMEs and startups, the lower of the fixed amount or percentage applies.

The separate Article 101 ceiling for intentional or negligent GPAI-provider infringements is EUR 15 million or 3% of worldwide annual turnover, whichever is higher.

Those are maximums, not automatic invoices. Buy around your systems, roles, evidence volume, and review cadence. A giant control library has little value if no one owns the records or can show which deployed version they describe.

EU AI Act tools at a glance

Prices and access paths below were verified against live vendor pages on 3 August 2026. "Custom" means the vendor did not publish a subscription amount, not that the product is necessarily expensive.

Six of the seven commercial vendors publish no subscription starting amount. IBM is the exception. That opacity changes the sensible buying process: shortlist by evidence fit first, then force every finalist to price the same inventory count, user count, integrations, implementation work, support level, and contract term.

How these tools were picked

This is a compared list, not a hands-on test claim. Each product was checked against its current product and pricing pages on 3 August 2026. Legal dates and duties were checked against current European Commission, AI Act Service Desk, and EUR-Lex sources. Products were then judged on seven buyer questions:

1. Inventory: Can it keep a usable register of systems, models, agents, datasets, vendors, owners, purposes, and versions?
2. Classification: Can it help identify operator role, risk category, applicable rules, and the reason for each conclusion?
3. Control and evidence mapping: Can it connect obligations to policies, controls, tests, approvals, and source evidence without duplicate work?
4. Technical assurance: Can it evaluate model behaviour or connect runtime signals to governance actions?
5. Change management: Can it preserve ownership, review history, incidents, exceptions, and evidence as a system changes?
6. Deployment fit: Does it support the cloud, model, and GRC environment in which the buyer already works?
7. Commercial clarity: Are tier names, limits, trial terms, and pricing visible before a sales call?

The ranking rewards breadth only when the product also exposes a credible operating workflow. A free scoping tool can beat an enterprise platform for a company that has not classified one system. A training platform can be valuable for Article 4 records while remaining the wrong tool for system governance. Products were dropped when their current public material did not support a decisive use case beyond generic compliance language.

1. Credo AI: best overall for complex AI portfolios

Credo AI is the strongest overall choice when one company needs to govern many AI systems, vendors, and teams under one operating model.

Its platform combines AI discovery and registry, risk management, policy mapping, evidence workflows, reporting, and runtime monitoring. The named EU AI Act policy pack covers risk classification, conformity assessments, governance workflows, automated evidence, and audit trails. Credo AI also says its ecosystem spans more than 30 hyperscaler, system-integrator, and enterprise-platform partners.

The concrete use case is a company with customer-service models, HR tools, internal copilots, vendor APIs, and experimental agents owned by different groups. Credo gives governance one place to define policy and gives each owner a scoped path to supply evidence. That is more useful than asking every team to interpret the Act independently.

Its biggest wall is commercial visibility. Credo publishes no tier names, subscription amounts, included inventory count, or self-service trial. A demo can establish product fit, but the purchase still needs a carefully normalised quote. Smaller companies with a dozen straightforward deployments may be buying more governance machinery than they can operate.

Best for: Enterprises and regulated scale-ups with distributed AI ownership and a mixed model estate
Standout: A named EU AI Act policy pack inside a broad policy-to-evidence governance system
Pricing: Custom order-form pricing; no public tier names or subscription amount as of 3 August 2026
Free trial: No public self-service trial; request a demo or get started

A practical Credo AI pilot

The top pick should prove a complete evidence chain, not just produce an attractive dashboard.

1. 1

   Choose three unlike systems

   Use one customer-facing generative feature, one internal decision-support workflow, and one third-party AI tool. Record purpose, owner, provider, model, users, geography, data classes, and deployed version for each.

2. 2

   Classify role and risk

   Run the EU AI Act workflow for all three. Ask the vendor to show the source behind each question, how a reviewer overrides an answer, and how the platform preserves the reason for the final classification.

3. 3

   Bind controls to existing proof

   Map five obligations to evidence you already hold, such as a vendor assessment, model card, security control, training record, or release test. Measure how much proof can be reused without copying files.

4. 4

   Change one system

   Swap the model version or add a new use case. Confirm which assessments reopen, who receives a task, what history remains visible, and whether stale evidence is clearly marked.

5. 5

   Export the decision trail

   Produce the record a legal reviewer, auditor, or authority would receive. It should show owners, sources, dates, approvals, exceptions, evidence, and version history without requiring a live product tour.

Verdict: Credo AI wins when governance complexity is the problem. Skip it when you only need to scope a few systems or preserve a simple training record.

2. Vanta: best for security-led evidence reuse

Vanta is the cleanest choice for a security-led company that already manages policies, controls, vendors, and audit evidence in Vanta.

The Vanta EU AI Act product includes more than 150 controls and 16 policies, plus guided workflows, risk-aligned templates, adaptive scoping, framework mapping, automated tasks, evidence collection, and incident or model monitoring. The core advantage is that an identity control, vendor review, policy, or access record may already exist for another framework and can be linked instead of rebuilt.

Picture a SaaS company that completed SOC 2 and ISO work in Vanta, then added AI features through third-party model providers. Security already owns vendor evidence and technical controls. Vanta lets that group extend a familiar operating rhythm into AI governance without introducing a separate control system on day one.

That same strength defines the limit. Vanta is not primarily a deep model-testing laboratory. A company needing specialised bias, robustness, adversarial, or drift testing should confirm the exact integrations and evidence path, then compare Holistic AI or IBM. Vanta also publishes four package names but no dollar amount for any of them.

Best for: Companies already operating security and compliance frameworks in Vanta
Standout: More than 150 EU AI Act controls and 16 policies with evidence reuse across frameworks
Pricing: Essentials, Plus, Professional, and Enterprise; all use personalised pricing with no public amount
Free trial: No public self-service trial; a free demo is available

Verdict: Vanta beats a separate AI-governance purchase when your existing Vanta program already contains most of the people and proof. The choice flips to Credo AI or Saidot when AI relationships and policy decisions, rather than security-control reuse, dominate the work.

3. Saidot: best EU-native collaborative governance

Saidot is the best fit for an EU-based or EU-focused organisation that wants a connected governance graph and a collaborative route from system context to policy and control work.

The Saidot platform connects systems, models, agents, datasets, risks, controls, and policies through a knowledge graph, so shared facts can inherit across records. Its library currently lists more than 260 risks, 620 controls, 110 policies, and 100 widely used AI models and products. Built-in connections cover Azure AI Foundry and Amazon Bedrock, with a REST API, webhooks, and MCP servers for other environments.

A useful scenario is a financial-services group with the same model provider used in several applications. One provider or model fact should flow to the affected systems, while local purpose, users, data, and controls remain distinct. The graph approach is designed for that relationship, where a spreadsheet produces duplicate records and contradictory answers.

Saidot's EU AI Act System Classification Assistant is promising but must be labelled correctly: it is Preview in release 8.14.0 dated 9 July 2026. It guides a structured questionnaire, prefills known system information, and separates organisation-level from system-level obligations. A buyer should test how preview status affects support, export stability, and contract commitments before treating it as the classification backbone.

Best for: EU-focused organisations that need shared governance context across connected AI assets
Standout: Knowledge-graph inheritance backed by 260+ risks, 620+ controls, and 110+ policies
Pricing: Subscription pricing is not publicly visible; contact Saidot for the current quote
Free trial: Yes; self-service onboarding or a facilitated pilot is offered

The trial is the opportunity to test inheritance. Create two systems using the same model, change one shared provider fact, and inspect what updates automatically, what requires review, and what remains isolated. If reviewers cannot understand why an obligation appeared, the graph is adding complexity rather than removing it.

Verdict: Saidot is the sharper EU-native option for connected records and collaborative control work. Skip it when you need public pricing, a fully general-availability classification assistant, or the deepest runtime test suite.

4. OneTrust: best for existing privacy and GRC estates

OneTrust is the sensible choice when AI governance needs to become another governed domain inside an established OneTrust privacy, data, or risk program.

The OneTrust EU AI Act solution registers AI systems, maintains inventory and ownership, links risks to systems, automates workflows and evidence, and connects runtime events to governance actions and post-market monitoring. Its AI Governance package also supports EU AI Act, NIST, and ISO/IEC 42001 tiering, approvals, attestations, evaluation gates, documentation, reporting, and continuous monitoring.

The best case is a multinational whose data-protection impact assessments, vendor records, policies, and risk owners already sit in OneTrust. An AI use case often touches the same personal data, processors, transfers, and business owners. Keeping those records connected can reduce parallel questionnaires and preserve a clearer ownership map.

The poor-fit case is a small product company buying OneTrust only for AI. The platform's value comes from the surrounding estate. Its public pricing page says AI Governance is metered by admin users and AI inventory, but it publishes no amount and no self-service trial. Buyers also need to ask exactly which technical evaluations are native and which arrive through integrations or uploaded evidence.

Best for: Organisations already using OneTrust for privacy, data governance, third-party risk, or GRC
Standout: AI records can sit beside existing privacy, risk, ownership, and evidence workflows
Pricing: Custom, based on admin users and AI inventory; no public subscription amount
Free trial: No public self-service trial; request pricing or a demo

Verdict: Choose OneTrust when the AI record should inherit owners and evidence from an existing OneTrust program. Choose a dedicated AI-governance platform when AI engineering, model relationships, and technical evaluation need to drive the operating model.

5. IBM watsonx.governance: best for hybrid stacks and transparent metering

IBM watsonx.governance is the strongest option here for a large hybrid environment that needs model evaluation, governance records, and a public route into the product.

IBM positions watsonx.governance as a multi-vendor governance layer with a connected Governance Graph, policy and control mapping, continuous audit reporting, inventory, and risk context. Its integrated compliance ecosystem spans more than 200 frameworks. The Compliance Accelerators add-on includes Credo AI Policy Packs aligned to the EU AI Act, ISO/IEC 42001, and NIST AI RMF.

The practical fit is an enterprise running models across clouds and internal infrastructure, with risk staff needing traceable records and engineers needing measurable evaluation. IBM publishes both limited free capacity and usage units, which makes a proof of concept easier to cost than the six custom-priced alternatives.

The product is not commercially simple. The live pricing page mixes model-management usage, GRC components, observability examples, AWS SaaS, and software deployment. A buyer must identify which components solve the intended job before treating any one figure as the platform price.

Best for: Hybrid and multi-vendor enterprises that need governance plus measurable model evaluation
Standout: Public Lite, usage, GRC, and observability pricing alongside support for 200+ frameworks
Pricing: Lite is free; Essentials evaluation units start at USD 0.64; GRC and deployment components are separate
Free trial: Yes; a Lite tier and a current free-trial route are available

IBM pricing, translated into buying units

IBM's Lite tier includes approximately 100 model evaluations, 100 global explanations, 50,000 local explanations, one inventory, three use cases, and three custom attributes per use case. That is enough to inspect the workflow, not enough to represent a scaled governance program.

Under Essentials model management, IBM lists USD 0.64 per model or template evaluation, USD 0.64 per global explanation, USD 0.64 per 500 local explanations, or USD 0.64 per 200 agent-message evaluations. The page's observability examples range from USD 1.28 per month for one model evaluated monthly to USD 161.28 per month for four models evaluated 30 times monthly, and USD 5,529.60 per month for eight models evaluated 360 times monthly. Evaluation frequency, not model count alone, drives the jump.

For GRC, Essentials lists USD 795 per instance, USD 2,650 per solution with a maximum of one, and USD 53 per concurrent user with a maximum of 25. Standard lists USD 3,710 per instance, USD 2,650 per solution with a maximum of five, and USD 53 per concurrent user with a maximum of 200. IBM also lists an AWS SaaS amount of USD 38,160 including one Governance Console or Model Risk Governance instance, 12,000 model evaluations per year, five AI use cases, and 25 concurrent users, but the page does not label a billing cadence beside that figure. Software deployment is priced by virtual processor core with no public VPC amount.

Verdict: IBM wins on hybrid breadth and inspectable entry pricing. Choose Holistic AI when runtime testing and enforcement should be the focused center of the purchase, or a lighter platform when the IBM component model exceeds the problem.

6. Holistic AI: best for technical testing and runtime enforcement

Holistic AI is the best fit when the compliance program needs technical tests and runtime policy enforcement, not only inventories and questionnaires.

The Holistic AI platform spans automated discovery, live inventory, risk testing, monitoring, policy enforcement, and audit evidence. It publishes more than 40 specialised tests across bias, safety, security, performance, drift, degradation, and adversarial threats. Its risk scores and regulatory templates map to the EU AI Act, NIST AI RMF, and ISO 42001.

The sharp use case is a business exposing an AI decision or generated output directly to customers. Governance needs to know not only that a policy exists but whether the system crossed a threshold in production. Holistic AI's enforcement layer logs the policy, input and output context, action, and outcome, which can connect a technical intervention to the later audit record.

The purchasing wall is familiar: Holistic AI publishes no tier names, subscription amounts, included test volume, or self-service trial. More than 40 tests is useful coverage, but the demo must show which tests work for your modality and architecture, how thresholds are validated, and what happens when a rule blocks or changes an output. A runtime control with poor fallback design can become a product-availability problem.

Best for: Customer-facing or regulated AI systems that need specialised tests and runtime policy enforcement
Standout: 40+ tests plus logged runtime actions connected to governance evidence
Pricing: Custom; no public tier names or subscription amount
Free trial: No public self-service trial; request a demo

Verdict: Holistic AI earns a shortlist when technical assurance is the evidence bottleneck. It is harder to justify when the main gap is ownership, basic classification, policy acknowledgement, or reuse of conventional security controls.

7. EU AI Act Compliance Checker: best free first step

The EU AI Act Compliance Checker is the correct starting point for a buyer who cannot yet state the organisation's role, system category, or likely obligations.

The European Commission and AI Act Service Desk checker asks structured questions to help providers, deployers, and other operators identify rules that may apply. It is free and available before any procurement process, which gives it unusual value in a market where six commercial vendors conceal starting subscription prices.

Use it for a first-pass record on each materially different system. A company providing an AI feature, deploying a third-party recruitment tool, and using an internal copilot may occupy different roles in different contexts. A single company-level label is too crude.

The checker is explicitly a beta and informational only. Its result is not legal advice and does not represent the Commission's assessment of your situation or obligations. It also does not operate a system inventory, collect ongoing evidence, test a model, assign controls, or monitor changes. Save the questions and inputs that produced the result, then route uncertainty to qualified counsel.

Best for: Free initial scoping before choosing counsel, controls, or software
Standout: Official question path tied to provider, deployer, and other operator roles
Pricing: Free
Free trial: Not applicable; the beta checker is available without a paid tier

Verdict: Every uncertain buyer should use the official checker before paying for software. No mature AI program should mistake its answer for the governance system that follows.

8. Trainual: best supporting layer for AI-literacy evidence

Trainual is a documentation and training platform that can preserve assigned guidance, completion, acknowledgement, and reporting for Article 4, but it is not EU AI Act governance software.

The useful fit is narrow and concrete. Article 4 asks providers and deployers to support AI literacy among staff and other people operating AI on their behalf. The Commission says no certificate is required and an internal record of training or guidance can be appropriate. Trainual's current packages provide documentation, group assignments, due dates, tests, tracking, reporting, version history, acknowledgements, and exportable CSV or PDF reports.

For example, a marketing group using generative media can receive system-specific disclosure guidance, complete a short assessment, acknowledge the current policy, and leave a dated record. A hiring group can receive different material tied to the systems and decisions it touches. The useful evidence is not a generic badge. It is the connection among role, material, version, completion, and follow-up.

Trainual does not publish capabilities for AI-system inventory, operator-role or risk classification, conformity assessment, model evaluation, or runtime monitoring. It belongs beside Credo AI, Vanta, Saidot, OneTrust, IBM, or Holistic AI when training evidence is weak. It should not replace them.

Best for: Organisations that need assigned, versioned, and exportable AI-literacy guidance records
Standout: Role-based training operations and acknowledgement evidence in a dedicated documentation system
Pricing: Core, Pro, Premium, and Enterprise use custom subscription pricing; a USD 1,000 one-time implementation fee is disclosed
Free trial: No public self-service trial on the current pricing page; request a demo

Trainual tiers without the sales fog

Core includes AI-assisted documentation, group training, due dates, testing, tracking, reporting, 2 GB of video storage, and 30-day version history. Pro adds individual paths, required-watch controls, completion nudges, 300 e-signatures per year, 15 GB of video storage, and 90-day history.

Premium adds unlimited e-signatures, unlimited video storage and version history, SSO, a custom brand and domain, 15 GB of SCORM storage, and training-path templates. Enterprise adds API and custom-integration support, access to SOC 2 documentation, extended migration and rollout help, dedicated customer success, quarterly reviews, and priority support.

The tier flip for EU AI Act evidence is about control, not prestige. Core can cover group assignment and reporting. Pro becomes relevant when individual paths, required-watch proof, nudges, or e-signatures matter. Premium is the step for SSO and unlimited acknowledgement or history. Enterprise is for integration, rollout, and assurance needs. Because the subscription amount is not public, require the quote to separate subscription, USD 1,000 implementation, content migration, and any authoring work.

Verdict: Trainual deserves this last place because Article 4 evidence is a live obligation and its training mechanics are relevant. It remains a support layer. Ranking it beside full AI-governance platforms without that warning would mislead the buyer.

Who should pick what

The fastest decision starts with the missing evidence layer, not the largest fine or longest feature list.

If you have no defensible system list, start with scope. Run materially different systems through the official checker, then create a minimum record with owner, purpose, role, users, geography, data, provider, model, version, and initial risk reasoning. Do not sign an enterprise contract to avoid this basic inventory work.

If the inventory exists but governance is fragmented, pick a program layer. Credo AI is the default for a complex, distributed estate. Saidot is the stronger alternative when graph relationships, EU context, and collaborative inheritance fit the operating model. Vanta wins when security controls and evidence already live in Vanta. OneTrust wins when privacy, data, vendor, and GRC relationships already live in OneTrust.

If documents exist but deployed behaviour is the uncertainty, pick a technical layer. IBM suits a hybrid, multi-vendor company that wants public entry units and broad governance context. Holistic AI suits a team prioritising specialised technical tests and runtime enforcement. Ask both to trace one failed evaluation through triage, exception, remediation, release decision, and exportable evidence.

If the systems are governed but staff guidance is unprovable, add Trainual. The platform should carry role-specific materials and completion evidence while the governance system remains the source for system scope and obligation context.

For a smaller company, the practical stack may be the official checker, a disciplined inventory, counsel for uncertain classifications, selected controls in the existing security system, and Trainual only if training records are scattered. For a scaling product company, Credo AI or Saidot can become the centre, with technical tests and training evidence connected around it. For a large hybrid enterprise, IBM or Holistic AI may provide the technical layer while OneTrust or an existing GRC system preserves broader organisational evidence.

If you are still designing the system rather than buying governance software, the production AI agent guardrails playbook explains how to limit permissions and failure impact. If the inventory includes agents, the AI agent platform comparison gives a separate route through the deployment layer. Neither replaces the legal and governance work described here.

The ones to avoid

Avoiding the wrong fit matters more than finding a universal winner. These products are credible within their lanes, but each becomes a poor purchase when stretched past it.

Avoid the official checker as a compliance system

The EU AI Act Compliance Checker is free, official, and valuable for initial scoping. It is also a beta whose result is informational rather than a Commission assessment. It cannot own controls, collect evidence, monitor a deployment, or keep the inventory current. Use it at the start, not as the file you present as a complete program.

Avoid Trainual as an AI-governance platform

Trainual can document policies and prove that named people completed assigned material. It cannot classify the governed system, perform a conformity assessment, evaluate model behaviour, or monitor runtime events. Buy it for the literacy-evidence gap, never because a training record feels like complete EU AI Act coverage.

Avoid Vanta when specialised model testing is the main need

Vanta's advantage is control and evidence reuse, particularly for an existing Vanta customer. If the unresolved question is bias, adversarial resilience, drift, or a runtime intervention, test the exact workflow before buying. Holistic AI or IBM may fit that centre of gravity better.

Avoid IBM when you need one simple commercial unit

IBM publishes more price information than the other enterprise products, which is welcome. It also separates Lite capacity, usage evaluation, GRC, observability, AWS SaaS, and software deployment. A buyer who wants one predictable package for a small inventory may spend too much effort assembling the right components.

Avoid Credo AI, Saidot, or OneTrust for a checkbox-only project

These systems create value through relationships, ownership, workflow, and repeated evidence. If leadership wants one questionnaire completed once, the implementation will expose that mismatch. Fix the mandate first. Governance software cannot supply the authority, staff time, and product change process that the organisation declined to fund.

Also avoid any vendor or guide that still presents 2 August 2026 as the blanket start of Annex III high-risk duties without reflecting Regulation (EU) 2026/1744. The current dates are 2 December 2027 for Annex III and 2 August 2028 for high-risk systems embedded in Annex I regulated products.

A 30-day buying process that produces evidence

The procurement process should leave you with better records even if you buy nothing.

Days 1 to 5: establish the sample

Choose five materially different systems, not five copies of the same chatbot. Include a customer-facing system, a consequential internal workflow, a third-party tool, a generative-content use case, and an agent or automation if one exists. Record the minimum facts and run each through initial role and scope analysis.

Days 6 to 10: define the evidence chain

For each sample system, choose two applicable or plausibly applicable duties. Name the source, owner, control, implementation proof, approval, current version, review cadence, and runtime signal. Mark uncertain legal conclusions for counsel. This becomes the common demo script.

Days 11 to 20: make finalists work in your scenario

Do not accept a prebuilt ideal-state demo. Ask the vendor to import or create the five records, reuse an existing control, route a disputed classification, expire stale evidence, record an exception, respond to a changed model version, and export the history. Include legal, security, product, engineering, procurement, and one business owner in the relevant portion, not every meeting.

Days 21 to 25: price the same unit

Request the same inventory size, reviewer and contributor counts, frameworks, environments, integrations, evidence history, support, implementation, and contract term from each finalist. Ask which limits cause the next price step. For usage-priced evaluation, model the expected number of systems, tests, and evaluation frequency rather than accepting a low-volume example.

Days 26 to 30: decide ownership before signature

Name the executive sponsor, system-record owner, legal reviewer, control owners, technical-test owner, incident route, and quarterly review process. Define which platform is the source for systems, policies, training, and runtime evidence. A product that becomes one more disconnected database has failed before launch.

EU AI Act questions buyers keep asking

What is the EU AI Act?

The EU AI Act is a risk-based regulatory framework for AI. Duties depend on the actor's role, the system or model, its use and risk category, and where it is placed on the market, put into service, or used. It covers public and private actors inside and outside the EU when those market or use conditions connect them to the EU.

What changed in the EU AI Act in 2026?

Article 50 transparency rules and enforcement for already-applicable provisions began on 2 August 2026. Regulation (EU) 2026/1744 also moved Annex III high-risk obligations to 2 December 2027 and high-risk obligations for systems embedded in Annex I products to 2 August 2028. Older pages showing one general August 2026 high-risk deadline are outdated.

Does the EU AI Act apply to US companies?

It can. The framework covers actors that place an AI system or general-purpose model on the EU market, put an AI system into service in the EU, or use one in the EU. A US headquarters does not by itself remove EU scope. Determine the role and system context, then obtain legal advice for an uncertain case.

What is the main goal of the EU AI Act?

The framework aims to protect health, safety, and fundamental rights while creating harmonised rules for placing AI on the EU market and using it. It applies different duties to prohibited practices, high-risk systems, transparency cases, and general-purpose AI rather than regulating every use in the same way.

What are the maximum EU AI Act fines?

Article 99 sets caps of EUR 35 million or 7% for prohibited practices, EUR 15 million or 3% for specified operator duties and Article 50 violations, and EUR 7.5 million or 1% for incorrect, incomplete, or misleading information, with the applicable turnover rule described in the law. SMEs and startups face the lower of the fixed amount or percentage. Article 101 separately caps certain GPAI-provider fines at EUR 15 million or 3%.

Is there an official EU AI Act compliance tool?

Yes. The EU AI Act Service Desk offers a free Compliance Checker. It is an ongoing beta for informational guidance, not legal advice or an official Commission assessment, and it does not replace an inventory, evidence workflow, technical testing, or monitoring platform.

Which EU AI Act compliance tool is best?

Credo AI is the strongest overall choice for complex, distributed AI governance. Vanta is better for an existing Vanta security program, Saidot for EU-native connected governance, OneTrust for an existing privacy or GRC estate, IBM for hybrid governance and public metering, and Holistic AI for technical testing and runtime enforcement. Start with the official checker if scope is unclear, and use Trainual only for the supporting literacy-evidence layer.
