Pangram, the startup best known for spotting AI-written text, has made its AI image detector widely available as Pangram Image 1.0. The tool moves out of research preview and now works on the web, through an API and inside the Pangram Chrome extension. A lighter sibling model, Pangram Image Flash 1.0, scans videos frame by frame to flag AI-generated footage.
What Pangram Image 1.0 Does
The new model looks at a picture and estimates whether it came from an AI generator. It can also produce a heatmap that marks which part of a photo looks AI-made, which helps when a real image has been edited with AI tools. That matters because many fakes today are not fully synthetic, just touched up in one spot.
Pangram says it trained the model to hold up against common tricks. Those include compression, blurring, added noise and the downscaling that social platforms apply to uploads.
Smaller images now supported
The research preview only accepted images of at least 512 by 512 pixels. Version 1.0 lowers that floor to 256 by 256 pixels, though results under 512 pixels come with a reduced-confidence warning. That is useful for thumbnails, profile pictures and low-quality reposts.
How the AI Image Detector Scored in Testing
To test image detection, Pangram took 100 real photos and asked 12 leading image generators to create close “mirror” versions with matching prompts. That produced 1,200 synthetic images. The company says its model reached 99.96% accuracy on this set.
Keep in mind these are the company’s own numbers on its own evaluation. Pangram says it also beat academic detectors on several public benchmarks, but independent testing will be the real proof.
| Model | What it checks | Claimed result |
|---|---|---|
| Pangram Image 1.0 | Still images | 99.96% accuracy on 1,200 AI mirror images |
| Pangram Image Flash 1.0 | Video, frame by frame | 98.7% on the DF26 benchmark |
| Next best video detector | Video | About 29 points lower on DF26, per Pangram |
Video Detection With Image Flash 1.0
Video is the harder problem, and Pangram points to the DF26 study as the reason. That research found people were barely better than a coin flip at telling real talking-head videos from AI ones. Pangram says Image Flash 1.0 scored 98.7% on DF26, a 29-point lead over the next best detector.
For its own test, the company gathered 129 real social media videos. It then used 14 frontier video generators to create AI copies that started from the same first frame and followed a description of the original clip. In total, 1,529 videos were compared across several commercial detection services.
You can now upload a video on Pangram’s site, and the Flash model will show which parts come back as AI. If you want background on spotting fakes by eye, our guide on spotting deepfake videos covers the basics.
Where You Can Use Pangram’s AI Detection
The launch spreads the models across three places, so both everyday users and developers can reach them:
- The Pangram website, for uploading images and now full videos
- The Pangram API, updated to handle both image and video detection
- The Chrome extension, which flags likely AI images as you scroll social feeds, shopping pages and rental listings
The browser extension is the most practical piece for regular people. Fake rental photos and AI product shots are a growing headache, and a quiet warning while you browse can save time and money. Scammers already lean on synthetic media, as seen in crypto deepfake scams and in the global Interpol deepfake crackdown.
What This Means for You
Detection tools are getting better, but none of them are perfect. Treat a result as one strong clue, not a final verdict.
- Use a detector before you share or act on a surprising photo or video, especially one asking for money.
- Check the heatmap when an image looks mostly real, since small AI edits are common.
- Be careful with tiny images, where Pangram itself warns about lower confidence.
- Combine tools with common sense: look for the original source, a date and other coverage.
If you already check written work, Pangram joins tools like the Copyleaks content detector in covering more than just text. You can follow more launches like this on our AI news page.

Conclusion
Pangram Image 1.0 takes the company beyond text and into the messier world of AI pictures and video. The claimed accuracy is impressive, though it comes from the company’s own tests. The Chrome extension and video upload make it easy to try, which is exactly what people need as fake media spreads. Watch for independent reviews to see how well it holds up in the wild.
