Check a claim without leaving the page. FactLens follows videos, podcasts, live streams, images, and posts, then shows a clear verdict with the sources behind it.
FactLens is a Chrome fact-checking extension built for the moment a statement sounds important and you want evidence now. Start an audio and video session to follow spoken claims as they happen, or scan visible images and social posts before choosing what to check.
Use the providers you prefer
FactLens supports Google Gemini, OpenAI, Anthropic Claude, Deepgram, compatible search services, and custom AI or speech-to-text endpoints. Provider availability depends on the checking mode and the model you select.
Built-in Browser Search is available without a separate search key. You can also connect another supported search provider when you need a different retrieval workflow.
FactLens Pro
Pro adds synchronized provider names, configurable audio/video and image/post workflows, mode-specific prompts and verdicts, credential fallback routing, source preferences, speaker reports, activity history, and the FactLens Console. Your actual API keys stay on the device where you enter them.
Privacy and control
You choose the AI, transcription, and search services FactLens uses. API keys remain in Chrome Extension Storage and are not uploaded to FactLens Cloud. Signed-in synchronization can carry settings, credential names, workflow configuration, and session data according to the controls available for your account.
FactLens is useful for journalists, researchers, students, educators, analysts, and anyone who wants to inspect a claim before accepting or sharing it.
FactLens provides evidence assistance, not a guarantee of truth. Always review important sources and use professional judgment for high-stakes decisions.
Factlens Console
Customize prompts, verdicts & rules. You define what you want to see, how you want to see & when you want to see.
