Authorship you can replay.

ProofWrite is three things working together: a writing canvas that records itself, an authorship record that can’t be faked after the fact, and a review console that turns that record into a verdict.

01 · the writer

A canvas that records itself

Writers get a clean, full-screen editor with markdown formatting and a live word count. Underneath, an event SDK captures the composition as it unfolds — keystroke timing, deletions, pauses, pastes, tab switches and periodic draft snapshots. None of it interrupts the writing.

02 · the record

A tamper-evident authorship timeline

Every session becomes an ordered event ledger — the raw material of proof. It captures how the essay was written without storing what was pasted (only counts and content hashes), so authorship is verifiable and privacy stays intact.

03 · the review

Judging backed by evidence

Judges open a console with a confidence-scored leaderboard, paste and tab-switch flags, and a 10× replay of how each piece was composed. Natural-language queries let Claude triage the field — surface the suspicious, shortlist the clean.

ProofWrite proves authorship from the shape of the writing — timing, rhythm, revision — and never stores pasted text. Counts and hashes, not content.
