ProWritingAid

Pros: It's actually helped me to become a better writer. There are so many reports and different features, all of which provide excellent information. It's fairly intuitive and has helpful pop-up suggestions displayed in your text.
You can customize the analysis by genre and even compare your writing to a well-known author. Lots of charts and graphs to provide overviews.
Has great ability to focus in on the worst errors.
Many of the features go far beyond simple spelling and grammar checks:
Style suggestions, duplications, clichés, overused phrases, too many to name here, but as I said, it made me a better writer by far.

Cons: A bit slow loading large documents. I would like better control over sections written in regional or other dialects. I wish there were an easy way to download and print the many reports available. If there is, I haven't found it. The overall summary report can be downloaded/printed, but there are so many others. I would like the changes I make within the uploaded document to be tracked in Word's change tracker.
Like any AI product, it will make wrong choices, but doesn't change anything automatically, so you can easily ignore an incorrect suggestion.

Overall: I am a fledgling writer and was looking for a better grammar checker than what is provided by MS Word, Grammarly and some others. I tried Autocrit and liked it a lot, I bounced back and forth for a while before deciding that ProWritingAid has even better features and ease of use.

Pros: I use the browser based free version of ProWritingAid for every piece of material I write. It's decent on finding grammatical errors with punctuation, etc. It's especially wonderful for picking up on typos and mistakenly typed words that our eyes tend to skip over, for example: typing "form" when you meant "from." It goes a step beyond grammar and can flag issues like passive voice, which is helpful if you have a difficult time seeing it in your own writing. I find PWAs cloud version works much better than Grammarly, which I could not get to work properly on my computer.

Cons: A percentage of the suggestions are incorrect--I'd guess perhaps 20%--so you need a fairly good foundation in grammar to know when to ignore PWA's suggestions. Or you can at least flag the change to ask your editor. I don't think the full program is worth the price, but it might be if you find it on sale.

Overall: I find ProWritingAid's online editor to be a crucial part of my editing process. I run every document through it before sending it off to others. Its suggestions aren't perfect, however, and the full program is too expensive.
