Pangram’s Chrome extension returned uncertain results for two images in an example shared by CEO Max Spero.
Pangram adds video assessments and Chrome image scanning, with paid access and limited free image checks.
Pangram AI detection now covers videos and images, expanding the company’s tools beyond identifying AI-generated text. Subscribers can upload clips for assessment and use its Chrome extension to check images while browsing.
The video tool assesses whether artificial intelligence helped create or edit a clip. Meanwhile, the browser extension automatically scans images and flags those it considers likely to contain AI-generated content.
How Pangram AI detection assesses videos
Pangram says its video tool distinguishes between partly AI-created clips and videos generated entirely with artificial intelligence. It also provides a heatmap highlighting areas of a video that likely contain AI content.
That distinction allows the tool to assess AI involvement beyond fully synthetic videos. For example, subscribers can submit a clip for an assessment of whether AI played a role in editing it.
The company says its underlying model performs particularly well when assessing videos from advanced AI systems. It also claims the model outperformed other detection tools in its testing.
In one internal test, Pangram reported accuracy above 98 per cent in identifying AI video content. That figure reflects the company’s own evaluation of the model.
Image scanning faces resolution and camera challenges
Pangram has also brought its Image 1.0 model to its Chrome extension after previously releasing a research preview. In company tests, the model identified more than 99 per cent of AI images, with a 0.27 per cent false-positive rate.
However, image resolution affects the confidence of its assessments. Pangram says results for images smaller than 512 by 512 pixels carry a reduced-confidence warning.
CEO Max Spero shared an example of the extension running on Pinterest, where it marked two images as uncertain. He also outlined a separate challenge in a post on X: smartphone cameras often use AI postprocessing to enhance real photographs.
Because of this, Spero said the model needed to handle camera processing while distinguishing AI edits from fully generated visuals.
The new video and image features are available to Pangram subscribers. However, users with free accounts can check a small number of images without taking out a paid plan.
