# signafAIde

Traceable, verifiable records of every wrapped tool call your AI agents make.

Evidence for AI regulation and audit, including EU AI Act record-keeping, ISO/IEC 42001 and SOC 2. Each record is signed by your agent, co-signed by the service and given a public timestamp. Auditors check it themselves with the open verifier. Only salted hashes leave your systems by default.

Using a coding agent? `npx signafaide agent setup`

## What a record proves

Each mark on an entry stands for one thing an auditor can check.

- **Who made it.** Signed with your agent's own key, which never leaves your machine.
- **That it has not changed.** Co-signed by the service and chained to the record before it. An edit or a gap shows.
- **When it existed.** After a public randomness round and before an hourly public timestamp.
- **What you rely on.** The open verifier code and the public drand and timestamp services, not the service's word. One command checks a record and says how many of its checks passed, and which are pending or could not run.

It does not say whether a decision was right. Records are evidence, not certification.

## Where to go next

- [Developers](/developers): wrap the tools your agent uses in Python or TypeScript. Records stay on your machine until you run `signafaide init`.
- [Auditors and compliance](/auditors): what each record gives you for the EU AI Act, ISO/IEC 42001 and SOC 2, and what an auditor checks.
- [Pricing](/pricing): free for 1 user and 25,000 live records a month. Solo is £19 a month, Team £49.
- [How it works](/how-it-works): where each part happens, the four steps, and how a record compares with a log you write yourself.
