Pangram, already known for software that identifies machine-written text, has broadened its scope to visual media. The company’s Pangram AI detection tools now include assessments for images and video, giving subscribers a way to examine clips and pictures for signs of synthetic generation or editing.
What the video tool does
Subscribers can upload a video and receive an evaluation of whether AI played a role in producing or altering it. According to Pangram, the system separates clips that are only partly AI from those generated entirely by AI. It also produces a heatmap that points to the areas of a video most likely to be synthetic.
Pangram says its video model is especially strong at catching output from frontier AI video systems and that it outperformed competing detection tools in its testing. In one internal test the company described, the model identified AI content with accuracy above 98 percent.

The side of the update builds on Pangram .0, which the company had previously offered as a research preview. That model is now available through Pangram’s Chrome extension, which scans images during ordinary browsing and marks ones that appear likely to be AI-generated.
Pangram reports that its model caught more than 99 percent of AI images in its testing, with a false positive rate of 0.27 percent. Those figures come from the company’s own evaluation rather than an independent review.
Limits the company acknowledges
Pangram notes that images below 512 by 512 pixels come with a reduced-confidence disclaimer. A demonstration shared by CEO Max Spero may illustrate why: in the Chrome extension running on Pinterest, two images that were plainly not real photographs were labeled as unsure.
Spero has also described a subtler problem for detection. Most phone cameras, iPhones included, apply some level of AI postprocessing to add detail to genuine photos. Pangram had to build a model that could tolerate that processing while still telling AI edits apart from fully AI-generated visuals. He told Pirate Wires that the model’s release was held back so it could be tested on several iPhone 18 Pros, because the model initially flagged photos from those cameras as AI.
Availability
The new and video detection features are live now for Pangram subscribers. People with a free account can check a small number of images without paying for a plan.
