The market for AI compliance software has exploded in the past few months. Enterprise platforms, GRC tools with AI modules, specialized startups, free checkers. Anyone looking for a solution is quickly faced with the question: What do I actually need?
The answer depends on who you are. A corporation managing 50 AI systems with an existing GRC stack has different needs than an SME with 10 AI tools and no dedicated compliance department. And this is exactly where the tools differ fundamentally.
In this post, we map out the market: What categories exist, who are they for, and where are the strengths and limits of each? Transparently, including our own position.
The four categories at a glance
AI compliance software is a catch-all term for very different products. We see four categories that clearly set themselves apart:
1. Enterprise AI governance platforms
This category targets large enterprises with complex AI portfolios. The platforms cover the entire AI lifecycle: from automatic shadow AI discovery to bias monitoring and policy enforcement to audit reporting across multiple regulatory frameworks.
Notable vendors: Credo AI, Holistic AI, IBM Watsonx.governance
Strengths
Comprehensive AI lifecycle coverage. Automatic AI discovery including shadow AI. Quantified risk scores across multiple dimensions (fairness, robustness, explainability). Multi-framework support (EU AI Act, NIST AI RMF, ISO 42001). Strong integration capabilities with existing tech stacks.
Limitations
High barrier to entry: pricing often in the five- to six-figure range per year. Complex onboarding requiring dedicated resources. Oversized for SMEs and mid-market companies. Steep learning curve, particularly with Credo AI. Geared more toward AI system providers than pure deployers.
Best for: Corporations and companies in regulated industries (finance, healthcare, insurance) managing dozens or hundreds of AI systems with an existing governance team.
2. Multi-framework GRC platforms
These tools aren't pure AI compliance solutions. They're broad compliance platforms that cover the AI Act as one of many frameworks. The upside: if you already manage ISO 27001, GDPR, or SOC 2 through such a platform, you can add the AI Act as a module.
Notable vendors: Vanta, OneTrust, Kertos, Venvera, caralegal
Strengths
AI Act integrates into existing GRC processes. Automatic evidence collection from cloud infrastructure and IT systems. Cross-framework mappings (reuse evidence for AI Act and GDPR simultaneously). For companies managing multiple compliance obligations in parallel, often the most efficient choice.
Limitations
AI Act is often just one module among many, not the focus. Guided risk assessment specifically for the AI Act sometimes less deep than specialized tools. Pricing starts at around 300 euros/month, enterprise variants significantly higher. For companies that only need AI Act coverage, often too broad.
Best for: Companies already using GRC software that want to add the AI Act as an additional framework without introducing a separate tool.
3. Specialized AI Act tools
This is the category where we operate with SimpleAct. Specialized tools that focus on exactly one job: registering AI systems, classifying them under the EU AI Act, and documenting them in an auditable way. Nothing more, but nothing less.
Notable vendors: SimpleAct, Daiki
Strengths
Fast onboarding: no months-long implementation. Guided risk assessment tailored to the EU AI Act. Accessible pricing for SMEs and startups. Focused on what the mid-market actually needs: inventory, classification, checklists, report. Less complexity, faster results.
Limitations
No comprehensive GRC management (no ISO 27001, SOC 2 in the same platform). No automatic AI discovery or model-level bias monitoring. For companies developing their own AI models (providers under the AI Act), documentation depth alone may not be sufficient.
Best for: SMEs and mid-market companies that use AI tools (deployers), want to prepare for the AI Act, and need a solution that's ready in hours, not months.
4. Free tools and compliance checkers
Several organizations offer free entry-level tools: the EU AI Act Compliance Checker from the EU Commission, risk assessment tools from industry associations, and free AI registry templates.
Strengths
Free. Good starting point for initial orientation. Helps understand whether the AI Act is relevant for your company.
Limitations
One-time assessment, no ongoing documentation. No storage, no versioning. No team access, no audit log. No exportable compliance report. Not sufficient as evidence for regulators.
Best for: As a starting point to assess your exposure. Not as a permanent compliance solution.
What to look for when choosing
Regardless of category, there are criteria that any AI compliance tool should meet if it wants to be more than a marketing feature:
AI inventory: Can you centrally register all AI systems with master data like name, provider, purpose, and responsible person?
Rule-based risk assessment: Is the risk class derived through a structured questionnaire, or is it just a free-text field?
Compliance checklists by risk class: Does each system get assigned the right requirements, with references to the relevant EU AI Act articles?
Audit trail: Are all changes logged in a tamper-proof way? Who changed what, when?
Exportable report: Can you export a structured compliance report as PDF or DOCX that serves as evidence for regulators?
Multi-user: Can multiple people work on the documentation with clear roles and approval workflows?
EU data hosting: Where is your data stored? Particularly relevant for European companies.
Where SimpleAct fits
We're not an enterprise tool and we're not a GRC all-rounder. SimpleAct is a specialized compliance platform for structured AI documentation under the EU AI Act. Built for the German mid-market.
What SimpleAct offers: central AI registration, guided risk assessment with rule-based classification, compliance checklists per risk class with EU AI Act article references, tamper-proof audit log, exportable compliance reports (PDF/DOCX), multi-user access with review system. Hosted in Germany (Hetzner, Nuremberg). Starting at 159 euros/month.
What SimpleAct does not offer: automatic AI discovery, model-level bias monitoring, multi-framework GRC (ISO 27001, SOC 2), GPAI provider compliance. For those requirements, you'll need a different or additional tool.
Our approach: Not trying to be everything for everyone, but doing one thing right. Giving companies that use AI a documented proof that holds up when it matters.
The right choice depends on your starting point
No single tool covers everything. Enterprise platforms are too complex and expensive for the mid-market. Free checkers aren't enough for ongoing documentation. And GRC platforms are a great choice if you already use one, but overkill if you only need the AI Act.
Choose the tool that fits your company size, your AI portfolio, and your budget. And get started. The best tool is the one that actually gets used.
