I would caution against tools like this. The detection of vendor signatures for AI-generated images is legit, but I'd probably rely on vendor software for that.

Many other techniques here are more or less quack science with some sordid history. If I recall correctly, the entire field was invented by a guy of questionable integrity. Most of these methods are riffs on "if you download a badly compressed JPEG, paste some higher-quality content into it, and then save it at high quality setting and the same resolution, it's going to show if you run a highpass filter on the result". This is not wrong, but commonly fails on innocent images and it's also not how professional photo editing is done.

Tools that aren't this seem even more questionable. The "clone detector" triggers on anything that naturally shows even a bit of symmetry or repetition. The "noise comparison" tool detects bokeh and smooth surfaces. Etc.

TL;DR: Experiment with it, but don't assume that just because it sounds scientific, it actually works in real life.
