Truthy - Real-Time AI Fact-Checker for Live Debates

  THE PROBLEM:
  Misinformation spreads faster than fact-checkers can verify it. Traditional
  fact-checking happens hours or days after debates, when false claims have already
  influenced millions. Live debates lack real-time accountability, allowing
  unchallenged misinformation to shape public opinion.

  THE SOLUTION:
  Truthy uses Gemini's Realtime API to fact-check spoken claims in under 5 seconds
  during live debates. It:

  • Transcribes two speakers simultaneously using Gemini Live sessions
  • Detects check-worthy factual claims (numbers, dates, comparisons)
  • Searches Google for authoritative evidence (.gov, .edu, official sources)
  • Displays color-coded verdicts (True → False → Unverifiable) with confidence scores
  • Shows clickable sources with publication dates for transparency
