Kristal

About

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.
