Fact-check anything, instantly. Live audio, text, and files, grounded in real sources. LitmusAI fact-checks in real time, right in your browser, using AI and live web search. Highlight text, scan a page, listen to a video, or upload a file, and get a rated verdict with sources. Free to start on our built-in AI, or bring your own key for Claude, OpenAI, Gemini, or Perplexity. WHAT IT CHECKS Highlighted text, scanned pages, spoken audio from any tab, and uploaded PDFs, images, or text files. Every verdict sits on a false-to-true scale with a confidence score and sources, and false or misleading claims come with the correct fact, not just a flag. MORE TOOLS Sentiment Analysis reads the crowd's mood in pasted comments or reviews. AI Detector checks whether an image or document is AI-generated, using verifiable Content Credentials where present. PLANS Free gives you 5 highlight checks for life, no card required, on our built-in AI. Pro ($5/mo) unlocks unlimited page scans, file checks, sentiment analysis, and AI Detector on your own API key. Max ($12/mo) adds live audio fact-checking. Manage or cancel anytime, payments handled securely by Stripe. PRIVACY Your check history stays in your browser. On the free plan, content you check is sent to the LitmusAI service, which forwards it to Google Gemini to run the check, and is used only to return your result. With your own API key, checks go straight from your browser to your chosen provider, never through our servers. Sign in with an emailed code, no password. We never sell your data, and there's no ad tracking.
