Great article, thanks for the tip on the AI Proofreader tool. Haven't seen it.
Not a big fan of AI (for its licensing/web scraping issues) but this looks like an interesting tool. I don't think I'd run a whole novel through it, but I ran a few paragraphs of the opening for my new novel and it didn't suggest any changes, so I know it's probably a good tool! Lol. I hope you get the joke. :-)
Grammarly helps tremendously with typos and spelling errors. It's not good at nuance, and it doesn't understand context at all. Word also has a fairly decent grammarly-like tool. Still, I don't write Medium stories without Grammarly turned on. Easy enough to ignore its suggestions if I wish.
