A browser extension that checks whether claims are accurate in real time, using Claude with live web search. Verify text, video audio, and files, right where you find them.
From a highlighted sentence to a whole video, get a grounded verdict with sources.
Highlight any passage or scan a full article. Claims are verified with web search and rated on a true to false scale.
Fact-check a YouTube or any video tab while it plays. The audio is transcribed and spoken claims are checked as they happen.
Upload a PDF, image, or text file to check the claims inside it, or ask questions grounded in the file.
Paste comments, tweets, or reviews to read the overall mood, the positive to negative split, and the themes driving it.
Check whether an image or document was made by AI, using verifiable Content Credentials where present, with an honest likelihood otherwise.
False claims come with the accurate fact, and you can ask follow-up questions about any result right on the card.
Start free. Upgrade when you want page scans, files, sentiment, and live audio.
Install the extension, then choose your plan and pay inside it. Cancel anytime. Payments handled securely by Stripe.
Your check history lives only in your browser. Content you check is used only to return your result, forwarded to the AI providers that power the checks (Anthropic, and Deepgram for audio). We never sell it, and there is no ad tracking. See the privacy policy for the full picture.
