What TruthLens is
TruthLens is a free, open-source browser extension that flags possible AI-generated text, synthetic images, and cloned voices in real time. Text checks examine signals such as burstiness, common-word ratios, phrase fingerprints, and syntactic uniformity. Image checks use pixel-level heuristics and look for known AI image sources including Midjourney, DALL·E, Stable Diffusion, Leonardo, and Ideogram. Audio and video checks examine spectral flatness, silence regularity, and pitch jitter. Clickable warning badges explain the signals behind a flag. Users can rescan with Ctrl+Shift+T or right-click an image for triage. The maker says detection runs on-device, with no uploads, accounts, or tracking. TruthLens is presented as a triage tool rather than forensic proof, and its signals can produce false positives and false negatives. The repository lists Chrome, Edge, Brave, Opera, Arc, and Vivaldi support. Installation involves downloading or cloning the repository and loading it unpacked through the browser’s extensions page. A signed Chrome Web Store release is planned after the public beta.
