ProofOrigin – voluntary proof of human writing

Let writers actively prove a text was written by a human, verifiably

Problem

AI text is increasingly hard to distinguish from human writing. A common observation: labs will never solve origin verification, but people who want to prove they wrote something have an incentive to voluntarily collect evidence. Today there is no lightweight, third-party-verifiable way to do that.

Solution

A writing-time attestation tool: it records keystroke cadence, version snapshots, and timestamps locally, then produces a shareable verification page. Readers can confirm a text was human-typed up to a point in time without trusting any AI detector.

Users

Bloggers, journalists, independent researchers, students, and any human writer needing proof of authorship

MVP

Browser extension records input events and timeline; generates a hash and a verifiable attestation page per article; exports PDF/JSON certificate; never stores the manuscript, only proof data; embeddable "human-written verified" badge

Revenue

Free basic attestation; annual subscription for long-term archival and custom-domain verification pages

Why now

AI detectors have been widely shown unreliable; proactive, opt-in human authorship proof is one of the few angles an indie can deliver without big-lab cooperation
