Sapien – Verifiable proof of human authorship through writing process tracking

Summary: Sapien captures and verifies the unique human writing process by tracking typing patterns, revisions, and idea evolution. It generates cryptographically secured proof tied to individual cognitive fingerprints, distinguishing human work from AI-generated text.

What it does

Sapien records typing rhythms and editing behavior in a Notion-like editor to document how ideas develop. It then creates secured proof of authorship based on these unique writing patterns.

Who it's for

Writers seeking to prove their work is human-generated rather than AI-produced.

Why it matters

It addresses flaws in AI detectors that analyze only finished text by verifying the authentic human writing process instead.
