// verified authorship engine

Prove a human
wrote it.

In a world where AI can write any essay in seconds, ProofWrite records how a piece was written — keystroke by keystroke — so authorship is something you can actually verify, not just trust.

The printing press did not kill the author — it multiplied them. Each new tool reshapes who gets to write, and what counts as writing

the problem

A finished essay tells you nothing about who — or what — wrote it. ProofWrite watches the writing, not just the words.

how it works
01

Writers compose in the canvas

A clean, distraction-free editor. Every keystroke, pause, deletion, paste and tab-switch is recorded as it happens — invisibly to the writer.

02

An authorship record is sealed

The session becomes a tamper-evident timeline of how the essay was actually written, plus thought-checkpoints that ask the writer to reflect mid-flow.

03

Judges review the evidence

A leaderboard with confidence scores, paste flags and a 10× replay of the composition. Ask in plain English; AI surfaces the suspicious sessions.

what gets recorded

The authorship record

keystroke recording

Every key, with timing and rhythm.

paste detection

Counts, sizes and content hashes — never the text.

thought checkpoints

Mid-session prompts to reflect on the work.

draft snapshots

Periodic fingerprints of the evolving draft.

pause & velocity analysis

Human cadence vs. machine-paste bursts.

ai pattern analysis

Flags compositions that don’t look hand-written.

tab & focus monitoring

Knows when attention left the window.

composition replay

Watch the essay get written, 10× speed.

// privacy-first — paste content is never stored, only counts & hashes

for judges & reviewers

Evidence, not guesswork.

Rank submissions by an authorship-confidence score. Replay any session at 10× to watch it composed. Filter the field in plain English — “show entries with no paste flags and deep revision” — and let AI do the triage.
