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, and you see when they agree or disagree. • "Why this score" shows the reasoning trail behind the number, not just the verdict. • Old footage, new frame: when a post presents an older event as if it were happening now, the check says so and names the actual date. The claim itself can be true while the post misleads, so this is reported separately and never quietly folded into the score. • Re-check with a different source set on demand. You stay in control. • Full Spectrum: steelmanned counter-views, source diversity and open questions, including perspectives beyond legacy media, kept evidence-based. • Sources are never filtered by origin. No mainstream bonus, no preference for official outlets. You judge. • Every quoted source attribution is checked by a second model that searches for the quote in the source text. No match means it is marked as not substantiated. • 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 popup and check it. Useful on sites that replace the browser's right-click menu. • Proof Library: a private archive of your verifications, each with a shareable public page. Free includes 5 checks a day plus a monthly taste of the paid depth. Pro and Power add a monthly allowance of Full Spectrum checks. Honest about the limit: measured, the paid depth is broader and easier to retrace, not measurably more accurate. Privacy-first: it only checks when you ask, and nothing runs in the background. The text you select is sent to be verified, and personal data such as emails, phone numbers and 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.
