Pangram expands its AI detection tools to video and images
Pangram, maker of a widely used tool for detecting AI-generated text, has released tools for spotting AI-made video and images. The features are available to subscribers.
Pangram, the company behind a widely used tool for detecting text written by artificial intelligence (AI), has extended its offering to cover AI-generated video and images. The new capabilities are available to subscribers and are meant to help users judge whether the content they see is genuine or machine-made.
Video detection
Subscribers can upload a video and receive an assessment of whether AI was used to create or edit it. According to the company, the tool can tell apart clips that are only partly AI-made from those generated entirely by AI. It also offers a "heatmap" showing which parts of a video are most likely AI-produced.
Pangram says the video model is particularly good at spotting the latest AI video and performed significantly better than other detection tools in its testing. In one internal test described by the company, the model flagged AI content with more than 98 percent accuracy.
Image detection
The company has also upgraded image detection. Its model, Pangram Image 1.0, was earlier released as a research preview and is now available through the company's Chrome extension, which automatically scans images while a user browses and flags those likely to be AI-generated. In testing, the model flagged more than 99 percent of AI images, with a false positive rate of 0.27 percent.
Limitations
For images below 512 x 512 resolution, results carry a reduced-confidence disclaimer, the company says. That may explain why an example shared by Pangram CEO Max Spero, showing the extension on Pinterest, returned an "unsure" result for two images that were clearly not genuine photos.
Spero noted further challenges: most phone cameras, including iPhones, apply some AI post-processing to add detail to real photos, so the model had to distinguish AI edits from fully AI-generated visuals. He told Pirate Wires that the image model's release was delayed so it could be tested on several iPhone 18 Pro phones, because it initially flagged images from their cameras as AI.
The new features are available now to Pangram subscribers. Users with a free account can check a handful of images without buying a paid plan.
