Imposter Shield - AI Image Detector

Flags AI images and videos as you browse. Reads the AI labels YouTube, TikTok and Facebook publish. Nothing is uploaded.

Imposter Shield tells you when a picture or a video you are looking at was made by AI. It reads the page itself, right on your computer. No account, no uploads, and nothing you browse is ever sent anywhere. The toolbar icon lights up green, yellow or red depending on what is on the page. WHAT IT CATCHES - Images carrying C2PA Content Credentials, the AI provenance standard - Generator fingerprints left in the file by Midjourney, Stable Diffusion, DALL-E and others - Images served straight from AI-only image hosts - Videos that YouTube or TikTok has labelled as AI, on a watch page, a Short or a TikTok video page, including the ones the platform caught by itself - Facebook posts carrying Meta's own "AI content" label, counted across a feed WHERE PEOPLE USE IT - Marketplace and rental listings with photos of places that do not exist - Dating profiles - YouTube Shorts, the TikTok feed and the Facebook feed - News and social feeds - Product shots and reviews BEING STRAIGHT WITH YOU Imposter Shield flags images that still carry an AI signature. Plenty of images have had that stripped by the time they reach a feed, and we would rather stay quiet than guess. A green light means we found no AI signature, not that we promise the picture is real. We are not going to invent a number to look clever. On video, the label comes from YouTube or TikTok, not from us. They can only label what they can prove, so a video with no label is not a video we are calling real. We show you what the platform knows and we tell you who said it. Facebook is a special case worth understanding. Meta uses one label, "AI content", for everything from touching up a photo to generating the whole picture from nothing. So we report that Facebook labelled a post, and we tell you exactly that much. We do not turn it into "this is fake", because Meta did not say that. PRIVACY Everything runs locally. There is no account and no tracking. The only thing that ever leaves your machine is a report you choose to send us when you think a flag is wrong. Free, and staying free.
