OriginProof is the black-box flight recorder for writers & creators — cryptographic proof a document was drafted by a human.
◈ keystroke dynamics · pause rhythms · revision history → Proof-of-Biological-Origin
Students failed, freelancers fired, contestants disqualified — by probabilistic guesses from Turnitin-style tools.
No detector score is admissible in court, defensible in appeals, or trusted by editors. Institutions need affirmative proof.
C2PA and metadata are stripped on copy-paste. Plain-text workflows have zero provenance today.
Universities, courts, publishers, and award juries increasingly require human-authorship proof. No standard exists — yet.
We don't analyze what you wrote. We certify how it came to exist — the biological texture no paste can fake.
This is why institutions will say yes where keyloggers and spyware got banned.
Drafting surface + live telemetry: paste ratio, revision rate, pause-σ, burstiness.
Signed Proof-of-Biological-Origin with chain hash, metrics, 10-yr registry.
Scrubbable replay + anonymized mode; one-click verifier links.
Registry API, Chrome extension, desktop app, Stripe billing — shipped.
| Stream | Price | Margin |
|---|---|---|
| Pay-per-certificate | $2.99/doc ($1.49 in 50-packs) | ~92% |
| Creator Pro | $16/mo unlimited | ~90% |
| Institution SaaS | $499–$2,900/mo | ~80% |
| Registry API | $0.08/verification | ~95% |
High-volume flywheel (creators) × high-retention contracts (institutions).
Integrity software + e-notary + publishing workflow + legal evidence.
6,000 HE institutions + 40k firms / publishers / newsrooms.
Wedge: universities burned by false positives + awards/publishers with immediate originality mandates.
| Player | Approach | Fatal gap |
|---|---|---|
| Turnitin / GPTZero | Content detection | False positives; no affirmative proof |
| C2PA / SynthID | Watermarking | Strippable; absent in text |
| DocuSign / Notarize | E-signature | Signs who — not how it was made |
| Keystroke-auth vendors | Biometric login | Authentication ≠ authorship evidence |
Every certificate makes verification standard; verifiers drive recorders.
Largest consented corpus of human drafting dynamics → best classifier.
SOC 2 + eIDAS timestamps + admissibility playbooks. Slow to clone.
LMS, CMS, e-filing integrations = deep switching costs.
