  Understand any YouTube video in seconds — and see what’s actually backed by research.
  
  EvidenceLens gives you fast, structured summaries of YouTube videos and shows which claims are supported by real scientific evidence.
  
  Unlike typical AI summarizers, it doesn’t just generate answers — it cross-checks claims against 200M+ peer-reviewed research papers and shows cited sources.
