The EU AI Act evidence pack: prove Article 50 compliance, don't just claim it
Last updated 31 July 2026
Compliance that isn't documented might as well not exist. If a market surveillance authority, an enterprise customer's procurement team, or your own board asks “are we compliant with Article 50?”, the answer needs to be a folder, not a shrug. This guide covers what that folder — an evidence pack — should contain.
What belongs in an Article 50 evidence pack
- A dated applicability assessment. Which of your systems fall under Article 50(1) (chatbots), 50(2) (synthetic content marking) and 50(4) (published AI media) — and, importantly, which don't and why. Our free checker produces exactly this record.
- The legal basis, quoted. The specific provisions you assessed against, with references to Regulation (EU) 2024/1689 — so a reviewer can verify your reading against EUR-Lex.
- Disclosure implementation proof. The wording users see, where it appears, and since when. Screenshots age badly; live monitoring (like weekly badge rescans) is stronger.
- Machine-readable marking records. For generated media: what marking you apply (e.g. C2PA signing) and volume logs showing it runs in production.
- An internal owner and review date. Evidence packs go stale; note who maintains it and when it is next reviewed.
Export one in a click
After completing the free checker, you can export a compliance evidence pack ZIP: your gap report as PDF, a timestamped questionnaire record, the quoted Article 50 provisions with EUR-Lex links, suggested disclosure wording, and an implementation checklist. It's the difference between “we ran a web quiz once” and a dated, reviewable compliance record.
Who asks for this in practice
- Enterprise procurement. AI vendor questionnaires increasingly include Article 50 line items — see our vendor due diligence guide. Sending an evidence pack ends that thread quickly.
- Market surveillance authorities, who can request information about your transparency measures.
- Insurers and auditors assessing AI-related exposure, especially given the Article 99 fine tiers.
FAQ
What is an EU AI Act evidence pack?
A bundle of documentation showing you assessed your obligations and implemented them: a dated record of your Article 50 self-assessment, the applicable legal provisions, your disclosure wording and where it appears, and proof of machine-readable marking for synthetic content.
Is an evidence pack legally required?
Article 50 itself does not prescribe a specific evidence format. But market surveillance authorities can request information, and demonstrating compliance is far easier with contemporaneous, dated records than with after-the-fact reconstruction. It is standard compliance hygiene, like a GDPR record of processing.
What does the AI Act Kit evidence pack export contain?
A ZIP with your gap report as PDF, a timestamped record of your questionnaire answers, the quoted Article 50 provisions with EUR-Lex links, suggested disclosure wording, and an implementation checklist — generated from your actual checker session.
Is the evidence pack export free?
Running the checker is free, and the evidence pack ZIP export is available directly after completing it. Ongoing monitoring evidence (badge rescans, disclosure statistics) comes with paid plans.
