Overview

Privacy-first writing provenance for Google Docs and Word for the web.

Authmarks is a writing provenance platform that seals a tamper-evident record of how your document was written — inside Google Docs, Word, or the Authmarks editor. A named person attests to the work, and anyone can check the seal. This is not an AI-detection score. AI detectors guess at outputs. Authmarks captures the process. WHAT IT DOES • Seals a verifiable record of authorship for any document • Works inside Google Docs — one click starts recording • Generates a C2PA-standard cryptographic seal you can share and verify • Supports institutional review workflows for academic and enterprise use • Anyone can verify a sealed record at authmarks.com/verify — no install needed WHO IT'S FOR • Students who need to prove submitted work is genuinely their own • Educators and institutions that require verifiable authorship evidence • Professionals whose writing carries legal, editorial, or compliance weight • Organizations preparing for EU AI Act transparency obligations PRIVACY-FIRST Recording is strictly off by default. You must explicitly consent, per document, before any session telemetry is captured. You can pause or revoke consent at any time. No telemetry is ever collected without your active, per-document permission. VERIFICATION Anyone — an instructor, a reviewer, a court — can check the sealed record at authmarks.com/verify without installing this extension. Provisional patent protection applies. Authmarks does not use your data for advertising. Your data is never sold. Privacy policy: https://www.authmarks.com/privacy Support: sales@authmarks.com
