FAQ

Questions?

How does Kweli work?

+

Kweli searches Google's Fact Check Tools database, which aggregates verified fact-checks from 100+ trusted publishers. Highlight text, paste a claim, or share a URL — Kweli instantly shows you what fact-checkers have found.

Is my data private?

+

Yes. Kweli only sends the text you're checking. We never track your browsing, store history, or sell data.

What languages are supported?

+

English, Spanish, Portuguese, French, and German — with more languages coming soon.

What if no fact-check exists for a claim?

+

Kweli tells you when no verified check was found. This doesn't mean true or false — just not yet reviewed by trusted sources.

100+ Verified Sources
