Tools FAQ

TruthLens tools — common questions

Which AI detection tool to pick, what each one does, and how to combine them.

Eight tools. Two run an actual analysis: the Video Legitimacy Checker for the claims in a video, and the AI Image Deepfake Detector for individual photos. Six run entirely in your browser with no account and no upload: the SIFT Fact-Checker, Source Credibility Checker, Logical Fallacy Checker, Misinformation Literacy Test, URL Safety Checklist and Image Verification Toolkit.

If you received a video and want to know what is being claimed in it, start with the Video Legitimacy Checker. If you have a screenshot or photo, use the AI Image Deepfake Detector. If you have a link in a message and want to know what to check about it, the URL Safety Checklist or the SIFT Fact-Checker are the right starting points.

Yes. Every tool has a free tier with no sign-up required. Paid plans add longer videos, larger images, higher daily quotas, batch analysis, and downloadable PDF reports.

No. The SIFT checker, Source Credibility Checker, Logical Fallacy Checker, Misinformation Literacy Test, URL Safety Checklist and Image Verification Toolkit all run locally. There is no server call, no upload and no account — you can confirm this by opening your browser's network panel while using them.
