wyper.io — Fact-Check

Fact-check any page, selection or video with dual-AI — a 1–10 truth score with real sources. Runs only when you ask.

Know what's true - with evidence. Select any claim, or point it at a page or video, and wyper.io Fact-Check returns a clear 1–10 truth score backed by real, linkable sources. • Two independent AIs cross-check each claim (Pro) - you see when they agree or disagree. • "Why this score" - see the reasoning trail behind the number, not just the verdict. • Re-check with a different source set on demand - you stay in control. • Full Spectrum (Pro): steelmanned counter-views, source diversity and open questions - kept evidence-based. • Works on any page, any text selection, and on videos (reads the captions). • Proof Library (Pro): a private, tamper-proof archive of your verifications. Privacy-first: it only checks when you ask - nothing runs in the background. The text you select is sent to be verified, and personal data (emails, phone numbers, card numbers) is stripped locally before anything leaves your browser. Built for everyday readers and for high-stakes work - journalists, researchers, legal, and anyone who needs verification they can cite. A tool that SUPPORTS your judgment, it does not replace it.
