Optics AI or Not is free and can detect AI-generated images and audio

"AI or Not" is able to detect AI-generated images and audio with 95 percent accuracy, according to developer Optic. Based on a proprietary algorithm, AI or Not can identify images from Midjourney, Stable Diffusion, DALL-E or even classic GANs as AI-generated. Uploaded images are not kept longer than necessary for analysis, according to Optic. However, the team is collecting feedback on the algorithm's performance - presumably to improve it further. In addition to images, the service can also recognize AI-generated music and other audio snippets. AI or Not for images and audio is free for small amounts of images. The company also offers an API that can be used to analyze larger data sets.
