AI-powered instant fact-checking web app that extracts and evaluates factual claims from any article in under 10 seconds.
Misinformation spreads online not because people want to believe false information — but because verifying claims is too slow.
Most articles contain dozens of statistics and factual assertions. Cross-checking even one claim can take hours. As a result, readers trust and share information without verification.
FadeThat removes that friction entirely.
Paste any article into the app and receive:
- A prioritized list of factual claims extracted from the text
- Verdicts for each claim: Wrong, Uncertain, or Correct
- A one-line explanation for every verdict
- A summary bar showing total claim breakdown by credibility
Claims are automatically ranked from most incorrect to most accurate, so dangerous misinformation appears first.
The entire flow completes in under 10 seconds.
- User pastes article text into the input screen
- Text is sent directly to the Claude API
- A structured prompt instructs the model to:
- Identify every factual claim (statistics, named assertions, quoted data)
- Evaluate each claim
- Return a structured JSON array
- Frontend sorts results by verdict priority
- Claims are rendered in grouped sections
Each claim object includes:
claim(exact verbatim quote)verdict(Wrong / Uncertain / Correct)reason(one-sentence explanation)
The app is fully stateless.
No backend.
No database.
No authentication.
Just paste → submit → results.
