Folio vs GPTZero
AI-text detection (with optional keystroke capture) vs. authorship proof that never watches you type.
GPTZero scans text for AI-generation likelihood, and its Writing Replay feature goes further, recording keystroke rhythm and copy-paste activity inside Google Docs to build a replay of how a document was written. Folio proves authorship a different way: a timestamped, hash-committed ledger of your drafts and sources, with no keystroke logging or behavioral profile, ever.
Where GPTZero shines
- Free tier available for individual use, with a large existing user base.
- Writing Replay gives instructors a literal playback of document history, which some find reassuring to review.
- Detection score plus replay together aim to catch what either alone might miss.
What Folio adds
- No keystroke or clipboard tracking, ever. Provenance is a byproduct of drafting and citing, not a surveillance layer bolted on.
- A cryptographic record (hash-chained, independently verifiable) instead of a behavioral trail only the vendor can interpret.
- No detection score to be wrong about. Folio doesn't guess whether text is AI-written, so it can't misfire on an honest writer's style.
Which should you choose?
Choose GPTZero if you want an AI-detection score plus a keystroke-level replay of how a Google Doc was written, and you're comfortable with behavioral tracking as the mechanism.
Choose Folio if you want proof of your writing process without being recorded while you write, and a verifiable record instead of a private replay.
Frequently asked
Does Folio track my keystrokes like GPTZero's Writing Replay?
No, and it never will. Folio's provenance model is explicitly built without keystroke capture or per-user behavioral baselines. It records drafts, sources, and edits as hash-committed ledger entries, not how you type.
Is Folio's approach as convincing as a keystroke replay?
It's a different kind of evidence: a cryptographically verifiable, tamper-evident record anyone can check at /verify/[code], rather than a video-like replay only GPTZero can produce or interpret.
Does Folio detect AI-generated text?
No. Folio doesn't do AI-text detection at all. It's not a substitute for a detector's judgment call; it's an alternative to needing one, by proving your process directly.
