Frequently asked questions

What to expect from Verfiai today.

Is Verfiai free?

Yes. Verfiai is free until October 13, 2027 under fair-use limits. After the one-year community-access period, Pro and Teams plans will be introduced. Existing users will receive advance notice.

Does the report verify facts on the live web?

Reports use live web search and AI-assisted evaluation. Search covers web, news, scholarly and structured-reference sources (including Wikidata and, where configured, professional fact-check verdicts from the Google Fact Check Tools database). Search results and AI conclusions can still be wrong, incomplete or outdated. Check each source independently.

How does the citation checker work?

References are checked against Crossref records and retraction notices. An unmatched citation is flagged for manual review, not declared fake. Crossref does not index every publication.

Which files can I use?

Reports accept .txt, .md, .csv, .docx and text-based .pdf files up to 5 MB. Scanned-image PDFs cannot be read. Citation checks accept .docx, .bib, .txt or .md up to 5 MB.

Where does my text go?

Questions and extracted document text are sent to the AI inference providers listed in our Privacy Policy; search queries go to the search and data services listed there (such as Tavily, Wikipedia, Wikidata, Crossref, OpenAlex and PubMed), and citation details to Crossref. Signed-in reports are saved privately until deleted. Do not upload confidential material. Provider retention policies may differ.

Is Verfiai free?

Verfiai is 100% free for everyone for the next year. Sign in with Google or email for the current monthly fair-use allowances. Reasonable rate limits protect service availability. Contact hello@verfiai.app for academic, educator or high-volume extended access. Paid checkout is unavailable.
