Nothing recorded yet.

The evidence is a by-product of writing. Write here rather than in Google Docs — only what is typed on the page becomes part of the record.

The record

Watch the essay rebuild itself.

Every keystroke, in the order it happened. Your professor watches a person write, and decides like a person.

The Receipts editor with a live evidence rail showing session span, revision ratio, thinking pauses, rhythm variance and pasted share. — 01Write in Receipts. The record builds itself as you go.

The replay view reconstructing a document mid-session with an event track of typing, deletions and pastes. — 02Scrub the whole session, keystroke by keystroke.

The exhibit view listing document hash, edit-chain hash, session span, revision ratio and process depth. — 03Send one link. Hashes, timings, the lot.

What this cannot do.

Stated plainly, not buried

It cannot read your mind: Retype AI output by hand and this records it as writing. Nothing can prove otherwise. Any product saying it can is selling certainty it does not have.
It is not another black box: It never scores how human your prose sounds. It shows what happened and lets a person judge.
It discloses your pastes: Paste something and the record says so. That is why a teacher believes the rest of it.
