Most fact-checkers work on articles. Glowby is an iOS app that works on video. Paste a TikTok, Reel, or Short and it pulls claims out of both the audio and what's on screen, then checks each one against sources ranked by a 13-category reliability system.
You get a 0 to 9.9 score. It's the minimum across the central claims, not the average, so one confident falsehood can't hide behind four true statements.
Every claim links to its sources. The full methodology is public.
