The InTruth browser extension, which uses Claude to fact-check claims made by politicians, has seen significant user growth and expanded its language support. The tool now operates in 16 languages, including Spanish, Arabic, Hindi, Portuguese, and French, and has reached over 11,400 users. InTruth identifies check-worthy claims in transcripts, gathers context via web searches, and then uses Claude to deliver a verdict based on accessible online information, not its training data. The extension remains free and open-source. AI
IMPACT This tool's expansion and user growth suggest increasing demand for AI-assisted fact-checking in public discourse.
RANK_REASON This is an update to an existing open-source tool that uses an AI model, rather than a new release from a frontier lab.
