Verify an AI agent's record

without trusting the company that ran it.

Etch evidence packs are built for the person who has to rely on them. The open-source verifier runs on your machine with no network calls. Each guarantee in the pack is labelled with the verifier that produced it, and the open-source check is one you run yourself, so the vendor and Etch cannot pre-cook it.

Offline verification against pinned public keys
Each epoch anchored in public logs (Sigstore Rekor, Bitcoin via OpenTimestamps)
Detects edits, removals and reordering of recorded entries
Export aligned with US Federal Rules of Evidence 902 (11, 13, 14) and EU eIDAS
Stated non-guarantees: detection not prevention, and no proof of completeness
