Documentation

How Clause50 works, what it records, and what it produces.

Clause50 keeps the paperwork that proves your AI system meets the EU AI Act's transparency duties. You describe the system once, and Clause50 works out which of those duties apply to it. Proof that you meet them — a statement from someone responsible, a document, or a record collected automatically from a system you already run — goes into a log that can be added to but never edited or deleted. From that log Clause50 produces a dated, tamper-evident document you can hand to an auditor.

Clause50 is not legal advice, a certification, or a conformity assessment. For a plain-English guide to the regulation itself, rather than to this product, read the EU AI Act guide.


More detail

Start here

What Clause50 does and how to get your first AI system set up.

Getting started

Sign in, name your organisation, and create your first AI system — the five minutes of setup before the real work begins.

Who it is for: Anyone who has just signed in and has nothing set up yet.

1. Define

Describe the AI system and see which transparency duties apply to it — the same first step as Define in the app.

Systems and intake

What an AI system record holds, where the intake questions come from, and what versioning means for evidence you have already recorded.

Who it is for: Whoever owns the description of the AI system — usually a product or engineering lead.

Coverage

What the score means, how gaps are counted, why upcoming obligations are excluded, and how it keeps itself up to date without you.

Who it is for: Whoever is asked how far along you are.

2. Prove

Record proof that you meet those duties, supplied by a person or fed in automatically by a machine.

Evidence

The four ways evidence arrives — a person states or uploads it, a connector or your own API pushes it — when to use each, why the record can never be edited or deleted, and how retraction lets you void a mistaken entry without erasing it.

Who it is for: Whoever will actually record proof: compliance, engineering, or both.

Connectors

The five connector types and what each one needs, getting an OpenAI or Anthropic Admin API key and a GitHub token, what each connector collects, the manual import format, and how hourly syncing works.

Who it is for: Whoever holds the OpenAI, Anthropic or GitHub credentials.

API

Push evidence in from your own CI, logs, or scripts with a per-system key: what it can and cannot do to your score, idempotency, and copy-paste examples.

Who it is for: Whoever owns the CI pipeline or the service that already produces the logs.

3. Generate

Produce the signed evidence pack and public disclosure text, and check that a pack is authentic.

Artifacts

Article 50 evidence packs and Annex IV technical files: draft to final, choosing the activity window, what ships inside the download, what the signature does and does not prove, and free preview versus paid download.

Who it is for: Whoever has to hand something to an auditor, a customer, or an authority.

Disclosure text

Generate the exact sentence your product should show for an Article 50 duty, in any of the 24 official EU languages, and why generating it does not by itself change your coverage score.

Who it is for: Whoever writes the words your users actually see in the product.

Verification

How to verify that an evidence pack is authentic and unchanged, what the signature proves and does not prove, and how to report a verification failure.

Who it is for: Anyone who has received a pack and needs to check it is genuine.

Reference

Everything that is not part of the three steps: notifications and short answers.

Alerts

The four kinds of alert in plain words, what the hourly pass actually does, and why an alert is a notification rather than a task.

Who it is for: Whoever needs to notice when something drifts.

FAQ

Short answers to the questions people hit in their first ten minutes.

Who it is for: Anyone who is stuck right now.

If you are stuck right now

Three questions account for most of the trouble people hit in their first ten minutes. Each has a direct answer:
