We Prove Human Effort, as You Type
Accused of using AI, when you didn't?
AI detectors often accuse honest writers. Proof of Effort detects real human effort, as it happens. Not a replay. Not by reading your text.
A new approach.

AI Detectors Guess About AI. Proof of Effort Proves Human.
Instead of an AI detector's guess about your text, Proof of Effort detects and measures your effort as you write. The record is yours. You decide who sees it.
AI Detectors read your finished words and guess whether a machine wrote them, a guess that gets less reliable as AI improves. Proof of Effort never looks at your words. It records how you write, the pauses, revisions, and reconsideration real composition leaves behind, and then seals that into evidence inside your document.
Already Been Accused?
The truth is, if you wrote something without Proof of Effort running, it can't manufacture a record that was never made. Retyping the work now would read as transcription, not composition, and we won't pretend otherwise.
But adopting it going forward isn't only about future work. Starting to document your effort, now, shows a good-faith effort to prevent exactly this kind of dispute, a step some reviewers will consider. And from this point on, every document you write carries its own evidence, so the next time your authorship is questioned, the answer is already in the file.
How It Works
-
Download LibreOffice, it's a powerful and free word processor similar to Microsoft Word.
-
Install the PoE extension into Libre. You can score existing proofs for free, but creating your own requires a license.
-
You write normally, in LibreOffice Writer. Proof of Effort runs quietly — no extra steps. Your proof of effort is stored inside the document.
-
When your work is questioned, you share the sealed proof. Anyone can verify it — free, on their own computer with the extension installed or with the online scoring tool. (Link on the Homepage)
What Makes It Different
-
Not AI detection. It detects and measures your effort directly, so there's nothing to guess about.
-
Never reads your words. It watches how you write, not what you write.
-
Non-biometric. It can't identify you — it measures against general human patterns, not a profile of you.
-
You own the proof, which can't be altered. Yours to share — or to strip from a file entirely.
-
Examinable, not a badge. Whoever checks your work sees the same real effort score of how it was made.
