AI-Generated Review

What is live-fact-checker?

This JavaScript Chrome extension acts as a real-time fact checker AI for YouTube videos and live streams, transcribing speech via captions, tab audio with local Whisper, or microphone input. It uses Gemini 2.0 Flash grounded in Google Search to spot verifiable claims—like stats or historical assertions in a Trump speech—and rates them TRUE, FALSE, or UNCERTAIN right in the browser side panel. Developers get instant, shareable HTML reports with sources, solving the pain of manual verification during live events.

Why is it gaining traction?

It stands out with three flexible transcription modes for zero-latency YouTube CC or any-tab audio, plus batch analysis for full videos with progress tracking. Budget-aware rate limiting keeps you under Gemini's free tier limits (15 RPM), while hover tooltips, click-to-expand modals, and bilingual English/Spanish UI make results scannable. The dark-themed side panel and exportable reports hook users needing quick real-time detection without server costs.

Who should use this?

Political journalists live fact-checking Trump speeches or debates, researchers verifying YouTube claims in real time, and podcasters analyzing interviews. It's ideal for anyone monitoring live streams who wants a dashboard-like view without building their own real-time transcription pipeline.

Verdict

Grab it if you're prototyping fact-checking tools—strong user-facing features and clear install docs make it a quick win, despite 29 stars and 1.0% credibility signaling early maturity. MIT-licensed and Manifest V3-ready, but watch for edge cases in non-YouTube tabs before production use.
