Fact-check any text or article using AI and web search for verification.

FactCheck, aka Rene: Think, Verify, Know. An AI-powered tool to democratize truth. WHAT IS FACTCHECK? FactCheck verifies text and articles as you browse, using AI and live web searches — so you can judge what you read on evidence, not vibes. HOW IT WORKS - Click the toolbar icon on any page for a full analysis, or right-click selected text to check just that passage - Claims are cross-checked against current web sources, not just AI memory - Clear plain-language verdicts — like "Mostly accurate" — with the reasoning, individual claims, and source citations behind every result - Honest about uncertainty: when there isn't enough evidence, FactCheck says so instead of guessing - Works with websites, social media posts, YouTube videos, PDFs, and more FLEXIBLE BY DESIGN - Free accounts include 10 checks per month; paid plans unlock more checks and our most capable AI models - Your choice of AI: subscribe and use our keys, or bring your own API keys in Advanced settings - Sign in once and your check history syncs with the FactCheck mobile app (iOS and Android) Learn more: https://www.ideasquantified.com/factcheck/ Terms of Use: https://www.ideasquantified.com/tos/ Privacy Policy: https://www.ideasquantified.com/privacy/
