P6
Local-first · Verifiable · Python 3.11+

Sign AI chat output into verifiable receipts.

P6 is a local-first AI co-processor. It wraps AI output in Ed25519 receipts, stores durable facts in a SQLite memory fabric, and keeps your keys and data on your machine.

Receipts demo

Every claim gets an Ed25519 receipt. Wrap a file, then verify the receipt without any network access.

# Sign a file and verify the receipt
p6 receipt wrap notes.txt
p6 receipt verify notes.txt.receipt.json

# Example receipt payload (signature abbreviated)
{
  "schema": "p6-receipt/v1",
  "claim_id": "receipt:...",
  "content_sha256": "hex-sha256-of-the-claim",
  "signature": "ed25519:...",
  "public_key": "ed25519:...",
  "created_at": "ISO-8601 UTC"
}
