Image Authenticity Checker Chrome Extension

No extension can certify an image as authentic. Different extensions answer different parts of the question: what the file says about itself, whether it carries a signed history, and what a detection model thinks of its pixels. Using them together gives the clearest picture.

Metadata reader: AI Image Detector

AI Image Detector (made by Patrick Bushe, who runs this site) reads an image's EXIF, IPTC, XMP and PNG data in your browser when you right-click it. It flags AI generator names, Stable Diffusion settings, IPTC tags that mark AI content and Content Credentials, and notes camera details that suggest a real photo. It can also scan pages automatically and badge likely AI images. The metadata check doesn't upload images; an optional Deep Scan sends an image to SightEngine or Hive using your own API key.

Its limit: if metadata has been stripped, as it is on most social sites, it can only say "No Metadata Found." It also counts any Content Credentials as an AI signal, though real photos can carry them too.

Content Credentials viewer

Adobe's Content Authenticity extension shows Content Credentials on images as you browse and lets you inspect them. For a single file, Content Credentials Verify gives the full signed history, including whether the signature is still valid.

Visual AI detectors

Hive offers a free extension that scores images and text for AI generation using its detection models. Scores are probabilities, not proof, and can be thrown off by compression, filters or unusual images.

Reverse image search

Chrome's built-in "Search with Google Lens" on the right-click menu finds other copies of an image, often the quickest way to discover where it came from. Google's "About this image" tool can show when Google first saw it and any metadata it found.

How to combine them

1. Right-click and check the metadata.
2. Check Content Credentials if any are found.
3. Search with Lens for the earliest copy.
4. Use a visual detector as one more signal if the rest is inconclusive.
