Attestari
Auditable, provably-deletable memory for AI agents
Open-source memory for AI agents you can actually audit. Every fact carries provenance (where it came from), the history is tamper-evident, and any user's data is provably deletable: forget() destroys their key and issues a signed certificate — data unrecoverable, audit proof survives. Reconciles GDPR "delete" with the EU AI Act "keep records." Zero-dependency core, runs on plain Postgres. Apache-2.0.
Hi Product Hunt 👋 I'm the solo founder of Attestari.
I kept hitting the same wall with agent-memory tools: they're black boxes. You can't prove where a stored "fact" came from, prove a user's data was actually deleted, or verify the history wasn't quietly edited — which rules them out for anyone under GDPR or the EU AI Act.
So I built the opposite. Attestari is event-sourced: an append-only, hash-linked log is the source of truth, and provenance, time-travel, and provable deletion fall out of it. Deletion works by encrypting each user's data under their own key — forget() destroys the key and issues a signed certificate, so the data is unrecoverable while the audit proof survives.
Don't take the claims on faith — `pip install attestari` and run examples/prove_the_moat.py; it attacks its own guarantees and self-verifies (asserts, not print statements). Apache-2.0, runs on plain Postgres.
Feedback welcome — especially from anyone who's shipped memory into a regulated stack (fintech, health, insurance). What would you need to actually run this?
