I do not know of any AI applications that will run on an Intel-based Mac under Monterey.
There are Web-based AI services that you can access from a browser like Safari or Firefox. For instance, Google's search engine has an AI mode, and can also search by photo.
Here's part of the output from a simple query about cats. Note that large-language-model AI engines are good at generating detailed text that sounds plausible even when it is totally wrong. But Google AI's output at least has a few links to sources, so you can visit those sources, and judge their reliability for yourself.

The Dezgo site lets you enter a text description to generate an image. E.g., this was the result when I asked it to generate an image of "A calico cat playing a piano."

There are others out there. Note that with any of these Web-based services, the sites could be gathering data on what you search or ask for, much as Google uses the results of regular Google search to drive targeted ads.
