# WritersProof > Cryptographic proof of human authorship. Build tamper-evident evidence of your writing process as you type. Canonical page: [https://chrome-stats.com/d/writersproof](https://chrome-stats.com/d/writersproof) ## Overview - **ID:** `writersproof` - **Platform:** Firefox - **Type:** Firefox add-on - **Status:** Available - **Publisher:** WritersLogic - **Category:** feeds-news-blogging,web-development,privacy-security - **Version:** 1.0.1 - **Last updated:** 2026-05-05 - **First published:** 2026-04-22 - **Size:** 98 KB - **Data as of:** 2026-09-11 - **Store listing:** [Firefox Add-ons Store](https://addons.mozilla.org/firefox/addon/writersproof/) - **Website:** [https://writerslogic.com](https://writerslogic.com/) - **Privacy policy:** [https://addons.mozilla.org/firefox/addon/writersproof/privacy/](https://addons.mozilla.org/firefox/addon/writersproof/privacy/) ## Description WritersProof witnesses your creative process and produces cryptographic proof that you — a human — authored your work. How it works: As you write in Google Docs, Overleaf, Medium, Notion, or 40+ supported editors, WritersProof silently records SHA-256 content hashes and inter-keystroke timing intervals. This data is chained into a tamper-evident evidence packet proving your writing happened over real time with natural human behavior. What it is not: Not a keylogger — never captures what you typed. Not AI detection — does not analyze your words. Not surveillance — no content leaves your device. Two modes: - Standalone (browser-only): SHA-256 hash chains stored locally. No installation required. Free. - Enhanced (with desktop app): Hardware-backed Ed25519 signatures, VDF time-proofs, and Secure Enclave binding. Who needs this: Students accused of using AI. Authors protecting manuscripts. Journalists documenting original reporting. Academics proving research integrity. Supported editors: Google Docs, Overleaf, Medium, Notion, WordPress, Substack, Ghost, Scrivener Web, and 30+ more. Privacy: Your manuscript content is never captured, stored, or transmitted. Only one-way cryptographic hashes and timing intervals are recorded. Everything runs locally. Standards: IETF Internet-Draft (RATS WG). CBOR/COSE wire format. C2PA compatible. IANA-registered CBOR tags. Apache 2.0 reference implementation.
