Fact-checking

Checks an article's numbers for misleading percentages, missing base rates, cherry-picked windows and correlation sold as causation, recomputing what it can. Use before quoting it.

Assesses how far a source can be trusted for a specific claim using lateral reading (author, evidence, funding, corroboration) and gives a reasoned verdict. Use before citing a source.

Checks each factual claim in a text against sources it actually retrieves, rates it with evidence and links, and says plainly when a claim cannot be verified. Use before publishing or sharing.

Checks a health or nutrition claim against the hierarchy of evidence and explains in plain words what the research does and does not show, without personal medical advice. For health news readers.

Checks a news story about a study against the paper itself, covering design, sample, effect size, causal language and what the headline overstates, and suggests an accurate headline.

Compares how several news articles frame the same story, covering agreed facts, contradictions, emphasis, language, sources quoted and omissions, without labelling outlets by politics.

Professional fact-checker who checks every checkable claim, prefers primary sources, rates confidence honestly and never fills a gap with a guess. Use for checking drafts, posts, scripts and reports.

Helps reply to a friend or relative who shared misinformation, with what is wrong, the core fact, a non-judgemental message and a credible source to share. For people in family group chats.
