The record

Product: TruthLens is a free, open-source browser extension that flags AI-generated text, synthetic images, and cloned voices in real time.
Text detection: Text checks use signals including burstiness, common-word ratio, phrase fingerprints, and syntactic uniformity.
Image detection: Image detection uses pixel-level heuristics and checks known AI image sources including Midjourney, DALL·E, Stable Diffusion, Leonardo, and Ideogram.
Audio detection: Audio and video elements are checked for spectral flatness, silence regularity, and pitch jitter.
Inline explanations: Inline warning badges can be clicked to show the signals behind a flag.
Scanning controls: Users can rescan with Ctrl+Shift+T and right-click an image to triage it.
Privacy: The maker says detection runs on-device, data is not uploaded, and there are no accounts or tracking.
Accuracy limitation: The maker describes TruthLens as a triage tool rather than forensic proof, and says its signals can produce false positives and false negatives.
Browser support: The repository says it works with Chrome, Edge, Brave, Opera, Arc, and Vivaldi, which are Chromium-based browsers.
Installation: Installation is described through cloning or downloading the repository and loading it unpacked in the browser's extensions page.
Release status: A signed Chrome Web Store release is listed as planned after the public beta.
Audience: The maker names journalists, teachers, researchers, parents, voters, and recruiters as intended users.
License: TruthLens is open-source under the MIT license.
