Fix your organizational
state forever.

SPEAudit creates a verifiable cryptographic certificate that proves a file existed in an exact state at a specific moment in time. Think of it as a "digital notary" — but based on mathematics instead of trust. If anyone modifies even a single byte of the original file, the certificate will immediately detect the change.

Legal teams needing timeline integrity for discovery. Compliance officers certifying document states for audits. AI governance teams proving what a model generated at a specific time. Any organization where "what existed when?" is a million-dollar question.

A raw SHA-256 hash proves content identity but not when it was computed or by whom. SPEAudit adds a timestamped Ed25519 digital signature, creating a portable proof bundle that includes the hash, the signature, the timestamp, and an independent verification kit — all in one self-contained package.

With local hashing (Chrome Extension or Desktop), no. The file never leaves your device — only the SHA-256 hash string is sent for signing. With web hashing, the file is processed server-side and immediately discarded after hash computation. Nothing is stored.

Every proof bundle includes a standalone verification kit with the public key and verification script. Your certificates remain valid and verifiable forever, using standard open-source cryptographic tools — with zero dependency on our servers or infrastructure.
