Take Control of What You See

MantaGuard is an AI image blocking extension – the first of its kind. It is your shield against AI-generated misinformation, empowering you to browse with confidence in an era of synthetic content.

AI-generated images are becoming incredibly realistic, making it easier than ever for misinformation to spread. If you can’t tell real from fake, then you’re at risk. There have already been cases where AI-generated content has been used to deceive, from fake political images to altered social media posts influencing opinions. As AI tools get better, this problem will only grow.

Whether navigating social media, conducting research, or simply exploring online, MantaGuard ensures clarity by blocking AI images instantly. Don’t let AI decide what’s real for you. Take back control with MantaGuard.

AI-generated image detection notification with options to unblock or report the image.

Prefiltering

  • These prefiltering thresholds can be edited by Ultimate users. An image will be prefiltered out if any of these thresholds are reached or exceeded.

  • Entropy Threshold: The randomness of an image’s pixels. Lower means less random, higher means more random.

  • Edge Density Threshold: Used to distinguish how detailed an image is. Lower means smoother with few transitions, higher means more complex with more transitions.
