I dropped an image that was color corrected with AI, but otherwise a proper image of myself. I use my own face because it's very easy to see if AI has altered it in a subtle way when dealing with a very familiar subject.

It found the "AI Generated" signature embedded in it by the creator (whatever image model Perplexity decided to use.)

But I wouldn't have called this image AI. So images that have merely been color corrected or other very minor changes may come up as "AI Generated" even if they're essentially real images.

I would say this is correct behaviour though. Any touchup by ai directly means it is strictly ai generated. Even if it looks almost identical to a nontampered original. This is exactly the kind of things you do want to catch. I also would just assume they simply look for the ai "watermark" for this.

All you've shown is that you have a different definition of "AI image" than the program does.
