A Chrome extension that fact-checks YouTube videos while you watch. It reads the subtitles straight from the page, the server pulls out checkable claims with timestamps, runs each one through human fact-checks, web search, and scientific papers, and shows the verdicts (true / false / unclear) in a panel next to the player. Clicking a timestamp jumps to the moment in the video where the claim was made; every verdict carries a source with a verbatim quote.

Could you build this?
Partial The Chrome extension, subtitle extraction, and claim pipeline are vibe-codeable, but trustworthy true/false/unclear verdicts depend on evidence retrieval and reasoning quality that is hard to get right.
What it would actually take: Architecture: a content script pulls transcripts, a backend extracts timestamped claims with an LLM, then queries sources such as the Google Fact Check API, web search, and Semantic Scholar or PubMed before an LLM judges each claim against the retrieved evidence. The hard part is calibrated verdicts and avoiding false confidence, which needs careful evaluation against labeled claim datasets and input from fact-checking or research expertise.
