Prove every client site is Article 50 compliant — without the spreadsheet hell.
Clause50 keeps audit-ready transparency evidence for all your clients’ chatbots and AI-generated content in one place. Tamper-evident, EU-hosted, exportable the moment a regulator or a client’s legal team asks.
You ship AI on dozens of client sites. Each one is a separate Article 50 liability — and the proof is yours to produce.
Every client is a separate audit
A regulator complaint or a client’s enterprise buyer can demand proof that a chatbot discloses it’s AI and that generated images are marked. Screenshots in Drive folders don’t survive scrutiny.
Proof goes stale every release
You redesign a site, swap a model, tweak a prompt — and last month’s evidence no longer describes what’s live. Keeping it current by hand across a client book is impossible.
Due-diligence questionnaires
Every enterprise deal now ships with an “AI Act evidence?” line. Answering it credibly, per client, on demand, is either a billable headache or a lost deal.
Does the EU AI Act apply to you?
If your organisation makes or uses AI that talks to people, generates content, or works with faces or emotions — and it’s offered in the EU or its output reaches people in the EU — Article 50 likely applies to you, whether you’re based in Europe or not. Its transparency duties become enforceable on 2 August 2026.
- You run a chatbot or AI assistant that interacts with people → Art. 50(1): tell them it’s AI.
- You generate or manipulate images, audio, video, or text with AI → Art. 50(2)/(4): mark and disclose it.
- You use emotion recognition or biometric categorisation → Art. 50(3): inform the people exposed.
From messy proof to a signed evidence pack in four steps.
Add a client system
Answer a 2-minute intake. Clause50 works out exactly which Article 50 duties apply to that system — no legal reading required.
Connect or upload
Link OpenAI/Anthropic/GitHub read-only, or drop in screenshots and configs. Evidence is collected and time-stamped automatically.
Watch coverage
A live score per client shows what’s covered and what’s missing, with a plain-English fix for every gap.
Export the pack
One click produces a tamper-evident, cryptographically signed PDF/DOCX pack — ready for a regulator or a client’s legal team.
Clause50 documents compliance — it doesn’t sit in your live traffic. Nothing to install on client sites, no code in the critical path.
One plan per portfolio. Cancel any time.
Every plan generates the same signed, auditor-ready evidence packs. What changes is how many AI systems you cover and how much of the reporting is automated for you.

Included on every plan, including Free
- Evidence volume is never meteredFile as much proof as you need. We never charge by record, by event, or by AI interaction — on any plan.
- Ingestion is never gated by planUploads and the ingest API work on every tier, including Free. Your plan decides what you can generate, not whether you may record evidence.
- Cryptographically signed, independently verifiableEvery finalised artifact carries an Ed25519-signed manifest. Anyone you send it to can verify it against our published key — without an account.
- Per-requirement evidence traceabilityEvery requirement in the document names the evidence its status actually rested on, by content hash — not a summary written after the fact.
- Machine-readable marking evidenceArticle 50(2) provenance is parsed and tiered from C2PA and IPTC/XMP manifests, rather than accepted as a tick-box claim.
- Signed audit-log exportYour organisation's full, hash-chained audit trail, exportable and signed, on every plan including Free.
Single-system evidence pack€149 one-timeexcl. VAT
A one-time purchase covering a single AI system for 6 months, for teams who need proof for one system right now and do not want a subscription. Generate signed, auditor-ready packs for that system, as often as you like, for the whole term. Buy it alongside any plan when you take on a system beyond what your plan covers.
- 1 AI system
- Signed, auditor-ready evidence packs
- Verifiable export bundle (ZIP + manifest)
- Connectors (OpenAI / Anthropic / GitHub) — on Solo
- Automatic alerts when things change — on Solo
Change your mind at any point in the 6 months? The pack price is credited against a subscription you start, less the months you have already used — so converting early costs you nothing, and converting late costs you only what you have had.
