Just Human and Proofwriter share the same core bet: your writing process is better evidence than a detector's guess. Where they differ is what you're actually writing in day to day.
| Proofwriter | Just Human | |
|---|---|---|
| Where you write | A distraction-free editor with themes, goals, and checkpoints | A plain textarea |
| Account needed to try | No — a no-account demo editor on the homepage | No — write and share with zero account |
| Proof of process | Checkpoints, revision history, and a blockchain-anchored timestamp | A watchable keystroke replay |
| Honesty about limits | Answers the "can this be gamed" question directly in an FAQ | States plainly that no algorithm can definitively prove authorship |
| Pricing | Free tier, then $8/mo or $72/yr for unlimited Proofs | Free, no paid tier |
Comparison based on Just Human's own public positioning and homepage copy at the time of writing.
Just Human keeps things minimal — write in a plain textarea, no account required, and share a keystroke replay as your evidence. That low-friction path is genuinely good for a quick one-off proof.
Proofwriter is built for people who are going to be drafting regularly — students, freelancers, journalists — and want an actual editor: themes, word-count and timer goals, checkpoints you can name yourself, and export to PDF, Word, or Google Docs. The proof mechanism is similar in spirit; the daily writing experience is the difference.
