# ISNAD

> ISNAD keeps the proof of what your AI did. It records where each answer came from, who or
> what handled it, and seals it in a locked record an auditor can check — the evidence the
> EU AI Act's record-keeping rules (Art 12 logging, Art 19 retention) will require from
> December 2027. Open source, Apache-2.0, self-hosted.
