CiteCheck
A browser extension and mobile app that, when you read a political opinion column or tweet, shows you which factual claims have been verified, contested, or contradicted by public documents — without telling you what to think.
news readers across the political spectrum who want to know whether claims in an article are supported before sharing them
- Inline highlight on factual claims in any news article, color-coded as verified, contested, or uncorroborated with links to the underlying record
- Cross-source fact-check consensus view that surfaces where independent fact-checkers agree or disagree, so users see disagreement rather than a single verdict
- Personal 'share-with-care' warning when you're about to forward an article that contains heavily contested claims, with a one-click counter-share that includes the context
- Weekly digest of the five biggest claim flips of the week so readers notice when narratives shift
