What Verify does
AI writing tools invent citations that look real but do not exist. The Verify tab in the Save to Folio extension catches them. Paste a block of text — a paragraph from ChatGPT or Gemini, a draft, a reference list — and Folio pulls out every citation and checks each one against CrossRef, the same database that underpins scholarly DOIs.
How to use it
- Open the extension popup and switch to the Verify tab.
- Paste the text you want to check.
- Click Check citations. Folio extracts the citations and verifies each one.
- You get a per-citation verdict and a summary at the top — for example, "5 real · 1 not found".
What the verdicts mean
- ✓ Real — the citation resolves to a genuine record. Either its DOI checks out, or a paper with that title exists in CrossRef.
- ⚠ To check — a similar paper exists, but the details do not quite match, or the cited DOI points to a different paper than the one described. Worth a closer look — the reference may be misremembered.
- ✗ Not found — no matching record exists. This is the classic AI fabrication: a plausible-sounding title and authors for a paper that was never written.
Saving the real version
When Folio finds the genuine paper behind a citation, the result has a Save the verified version button. One click adds the correct, verified record to your library — so if the AI got the details slightly wrong, you end up citing the real thing.
What it checks, and what it does not
- Verify confirms that a cited work exists, matching on DOI and title.
- It does not verify that a paper actually says what the text claims — only that the paper is real. Always read the source before relying on a specific claim.
- The AI only structures the text into citations; the real-or-fake verdict comes from CrossRef, deterministically. That means the checker itself cannot hallucinate a result.
Plan limits
Verify uses your Scholar AI allowance. The free Scholar plan includes a monthly taste; Fellow and Chair raise the limits substantially. See Plans and billing.
