Proofprint watches how you write — not what you write — to verify that a real human created the content. Earn a cryptographic badge of authenticity that anyone can verify.
Write naturally. Proofprint quietly observes four behavioral signals in the background, then generates a verifiable score.
Use the Proofprint editor just like any writing tool. Your ideas, your flow, your pace.
Four behavioral signals — keystrokes, revisions, copy-paste, and session continuity — produce a 0–100 authenticity score.
Get a cryptographically signed badge with a unique verification link that anyone can check.
Proofprint never reads your content. It only observes how you create it.
Natural typing has rhythm — bursts, pauses, varying speeds between words. AI-generated text pasted in bulk has none of these patterns.
Humans rethink, rephrase, and restructure as they write. Proofprint tracks deletions, insertions, and cursor jumps that reveal genuine editing.
A little pasting is normal — a quote, a link. But content created mostly by pasting large blocks scores lower on authenticity.
Real writing takes time. Proofprint checks that the session duration, word count, and interaction patterns are internally consistent.
Whether you're publishing a novel or filing a story on deadline, your audience deserves to know a human wrote it.
In a world flooding with AI-generated books, Proofprint gives readers confidence that your manuscript was genuinely crafted by hand.
Credibility is everything. Proofprint lets reporters attach verifiable proof that their reporting was human-authored, not machine-generated.
Stand out from the noise. A Proofprint badge tells your audience that the content they're reading came from a real person with real thoughts.
All keystroke and behavioral data stays on your device. Proofprint never sees your content — only the aggregate behavioral scores are transmitted to generate your signed badge. No tracking, no data collection, no content storage.
Write at least 50 words in the editor and Proofprint will do the rest. Free to use, no credit card required.
