Now that I’ve been using iA Writer for my blog, I thought I’d give Apple’s A.I. engine another try. It’s activated for this article. Another reason to return to using A.I. is that it has been enhanced and improved in Golden Gate, the upcoming macOS.
To utilize A.I. in the iA Writer App, select the text you’ve written and right-click on it. A dropdown menu will then appear.

If you select Writing Tools, you are presented with these choices:

You can rewrite, proofread, and perform several other tasks to enhance your text. However, you don’t have to accept the rewritten text provided by Apple’s AI. You can choose to ignore it, which I sometimes do.
I have not used the A.I. writing tools much in iAW, but I intend to continue for a while. It does rewrite my text well.
