Possiblymadebyahuman is a privacy-preserving system for recording and verifying the editing process of written content. It captures edit events (timing, location, size, operation type) as a hash-chained log without storing the actual text, and publishes verifiable records at short links. Producers include a Chrome extension, a browser writing page, and an Emacs mode, with optional salted commitments to text for later verification. The project is technically interesting for its content-blind capture and hash-chain verification, though its real-world utility for proving human authorship remains debatable.

Target audience: writers, journalists, editors, and developers interested in content provenance
