Writing receipts for creators and platforms in the AI era.
ByHuman creates signed proof of how online text was written, so creators can publish with writing receipts and platforms can identify authentic content signals.

New · ByHuman Feed Filter
The same extension now filters crypto spam, promotions, and excessive formatting out of your X feed: a local filter without limits, plus an opt-in Deep Filter.
Clean up what you read first. Then take the next step: publish your own posts with writing receipts that prove how you wrote them.
The problem
More content than ever. Weaker trust signals than ever.
01
Writing has changed.
AI-assisted writing is becoming normal across the web.
02
Detection is guessing.
Readers need better signals than guess-based detectors.
03
Process is the proof.
Creators need a way to show how text was written.
“AI detectors guess. ByHuman proves how text was written.”

Trust
ByHuman records writing signals, not your private browsing.
We measure composition behavior such as typing, pasting, editing, and kept text. The receipt shows proof of the writing process, not a private surveillance log.
