Folio vs Originality.ai
An AI-detection score (plus plagiarism and fact-checking) vs. proof your writing process actually happened.
Originality.ai scans text and returns a 0–100 score estimating the likelihood it was AI-generated, alongside plagiarism matching and a fact-checking pass — built mainly for editors and publishers vetting AI-assisted submissions at scale. Folio takes a different approach entirely: it doesn't score your text for AI fingerprints. It builds a timestamped, hash-committed record of your actual drafts and sources as you write, so you have evidence of your process instead of a probability about your prose.
Where Originality.ai shines
- Combines AI detection, plagiarism checking, and a fact-verification pass in one tool — useful for editors vetting freelance or AI-assisted submissions at scale.
- Paragraph-level highlighting shows exactly which passages triggered the AI score, not just a single document-wide number.
- API and LMS integrations (Moodle, WordPress) slot into existing editorial or classroom pipelines without a separate portal.
What Folio adds
- No detection score to defend or dispute — Folio proves your writing happened instead of estimating whether it looks AI-written.
- A cryptographically verifiable record (hash-chained, Merkle-provable) that anyone can check independently, not a percentage only Originality.ai's model can explain.
- Free to start — Originality.ai has no ongoing free tier; every scan draws down paid word-credits.
Which should you choose?
Choose Originality.ai if you're an editor or publisher vetting AI-assisted submissions at scale and want a detection score plus plagiarism and fact-checking bundled into one paid tool.
Choose Folio if you want to prove your own writing process directly, for free, instead of paying per scan for a score that only estimates the answer.
Frequently asked
Does Folio detect AI-generated text like Originality.ai?
No. Folio doesn't analyze text to guess whether it was AI-written — it instead proves your own writing and research process happened, with a verifiable record you control, not a probability score.
Does Folio also check plagiarism or facts like Originality.ai?
No — Folio doesn't run plagiarism-matching or fact-verification scans. It focuses on proving your own writing process; pair it with a dedicated plagiarism tool if your institution requires that check separately.
Can Folio replace Originality.ai for my team?
Not as a drop-in — Originality.ai's plagiarism-matching, fact-checking, and AI-detection score serve a different purpose. Folio is a complementary approach: proof of process instead of (or alongside) a detection score.
