AI-powered YouTube fact-checker and research companion Kristal is your AI companion for YouTube. It watches alongside you, automatically fact-checks what's being said every 20 seconds, and lets you ask questions about the video at any time — all without interrupting your viewing experience. How it works: → Navigate to any YouTube video or Short → Kristal appears and asks if you'd like to watch together → Click yes — captions turn on automatically → Kristal begins fact-checking in real time, scoring every claim from 0–100 Two modes: ◆ Fact Check — Kristal automatically analyzes what's being said every 20 seconds and delivers a summary, key claims, verdict, and accuracy score ◆ Ask — Switch to have a live conversation about the video. Ask anything about what's been said so far You don't have to stay on the video. Minimize Kristal and go do other things — it keeps listening in the background. Come back whenever you want to check in. Works on YouTube videos and YouTube Shorts. Privacy & Safety: → No personal data is collected or stored → Video captions are sent to Anthropic's API only to generate fact-checks and answers, and are not retained after the session ends → Your browsing activity is never tracked or shared → All processing happens in real time and is discarded when you close the tab
