Is there an alternative, non-AI, editing software?

GenAI is optional.

I don’t use AI in commercial artwork for copyright reasons. But that doesn’t keep me from using all the other tools in Photoshop & Illustrator.

Thanks everybody. That’s all very helpful stuff and much appreciated. 

The only image editor worth its salt without any generative AI (stable diffusion) features is PhotoLine. It does offer machine learned features such as a smart remove tool, but this is in line with Photoshop's feature list before stable diffusion hit the market. Overall an excellent image editor.

Krita, while focused on digital painting, is also a reasonable to good image editor without built-in genAI functionality.

Gimp was already mentioned. 

I did a search and supposedly Gimp does not contain AI Features by default, though plug-ins exist.

There is a general misunderstanding that generative AI is diffused into most standard Photoshop functions now. That is not correct.

It’s easy to avoid the generative AI functions in Photoshop.

• Remove Generative Fill etc from the menus (Edit > Menus). Disable the contextual toolbar.
• For the Remove tool, and any other tools that might optionally use genAI, there is a rolldown in the options bar. Just set it to not use generative AI, and that setting will stick and not bother you again.

And correct, if you ever see a popup asking you to accept terms and conditions, you’ve accidentally chosen an AI tool. Just don’t accept.

Now, AI has recently started to pop up in ACR as well, in the form of generative expand. I haven’t looked closer into that yet, but basically, it’s just a question of not clicking that button.

You can also enable this option in the preferences to stop the AI promotional stuff and popups

I forget who it was but one of the Forum regulars mentioned that by never confirming the AI/Firely terms of use they kept the Generative AI out of their installation of Photoshop, (Technically the Remove Tool is, if I understand correctly, also an AI implementation even if »simpler« than generative fill.) 

In Photoshop you could remove the Remove Tool from the Toolbar (Edit > Toolbar) and choose not to use Generative Fill, Generative Expand, … not exactly what you seem to be after, so you may want to also add your vote to this Feature Request:

Hardly any image editing software comes without AI features these days. They provide significant support in day-to-day work, and there are various functions I wouldn't want to do without.

But if you don't want to use these features, no one is forcing you to. You can use Photoshop without the AI ​​functions, too.
