WritersProof

Prove you wrote it. WritersProof captures cryptographic evidence of your writing process across web editors and publishers.

WritersProof witnesses your creative process and produces cryptographic proof that you — a human — authored your work. HOW IT WORKS As you write in any web based text editor, WritersProof silently records: • SHA-256 content hashes at regular checkpoints (never your actual text) • Inter-keystroke timing intervals (milliseconds between key presses) • Revision patterns and editing behavior This data is chained into a tamper-evident evidence packet that proves your writing happened over real time, with natural human behavior, in a specific sequence that cannot be fabricated after the fact. WHAT IT IS NOT • Not a keylogger — never captures what you typed, only that keys were pressed • Not AI detection — does not analyze your words or make statistical guesses • Not surveillance — no content leaves your device, ever TWO MODES 1. Standalone (browser-only): Lightweight SHA-256 hash chains stored locally in your browser. No installation required. Free. 2. Enhanced (with desktop app): Hardware-backed Ed25519 signatures, VDF time-proofs, Secure Enclave/TPM binding, and ENFSI-compliant forensic reports. Requires the free WritersProof desktop app. WHO NEEDS THIS • Students accused of using AI on assignments • Authors protecting manuscripts from plagiarism claims • Journalists documenting source-original reporting • Academics proving research integrity • Anyone who needs to prove they wrote what they wrote PRIVACY Your manuscript content is never captured, stored, uploaded, or transmitted. Evidence consists only of one-way cryptographic hashes, timing intervals, and document size changes. All processing happens locally on your device. Open-source reference implementation available for audit. STANDARDS Built on an IETF Internet-Draft (RATS working group). CBOR/COSE wire format (RFC 8949, RFC 9052). C2PA content provenance compatible. IANA-registered CBOR tags. Apache 2.0 licensed reference implementation.
