Pangram, known for spotting AI-written text, now offers a free-to-try-style check for AI photos and videos on the web, in a Chrome add-on and through its API.
Pangram, a company best known for detecting AI-written text, has released a tool that checks whether a picture or video was made by AI. It is called Pangram Image 1.0. It had been a research preview, and it is now widely available on the web, through the company's API and as a Chrome browser extension.
You can run an image through the tool to see whether it looks AI-generated. Pangram says it can also show a heatmap, which highlights the parts of a picture that look AI-made. For video, you can upload a clip on the company's website and get a verdict. Videos are checked frame by frame, using a lighter and faster model called Pangram Image 1.0 Flash.
The extension is the part most people will notice. It flags AI content as you scroll. Pangram says it works on social media, online shopping sites, rental listings and other pages with images. That makes it a quick way to question a too-perfect apartment photo or a product shot.
Pangram claims 99.96% accuracy on images, measured on its own evaluation set. The company lists rivals at lower scores:
For video, Pangram's figures are 98.57% in one post and 98.7% in the article. It puts the next best detector at 84.2%. To test video, it took 129 real social media videos and made AI versions of them with 14 recent AI video models.
All of these numbers come from Pangram's own tests, not an outside review. Pangram says it trained the tool to hold up against compression, blurring and added noise, which often fool detectors.
The tool now accepts images as small as 256 x 256 pixels, down from a 512 x 512 minimum at launch. Anything under 512 pixels comes with a reduced-confidence warning. The material does not say what the tool costs or whether the extension or video checks are free.
Before trusting a rental listing, a product photo or a viral clip, a quick check can help. Treat the result as a hint, not proof. A high score on the company's own tests does not mean every real-world result will be right, so pair it with common sense, such as checking who posted the content.
Pangram's new tool can give a quick read on whether a photo or video is AI-made, but treat its answer as a hint, not proof.
