Overview
Check any claim, page or video: a 1-10 truth score with real, linkable sources. Two AI models cross-check. 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. • Full Spectrum adds a third model of different origin, reading the SAME sources, so a disagreement is a different reading rather than a different search. • "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, including perspectives beyond legacy media, kept evidence-based. • Works on any page, any text selection, and on videos, it reads the captions, and when a video has none it analyses the video itself (clearly labelled as AI video analysis). • Paste a link instead: drop any X post, YouTube link or article URL into the extension popup and check it, handy on sites that replace the browser's right-click menu. • Proof Library (Pro): a private, tamper-proof archive of your verifications. We publish our own measurements with the raw data, including the results that do not flatter us: https://wyper.io/fact-check-different 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.
