I love this new functionality, it's better than the previous add on, although I ranked it 4 because it loads slower (both for the initial load of the screen and the analysis) than both the web editor and the old add on. My one suggestion: ProWritingAid needs a "find and replace ALL" function. While it does find and replace several things that it found in an analysis, users can't find and replace a word (say I keep mistyping Michael as Micheal and noticed it through the extension, I don't want to manually go through all Micheals and would rather 'find and replace all instances' which ProWritingAid does not support. You'd have to go to the original google docs to do it, then reload prowriting aid again, which is a hassle!)

It has helped me a lot with writing my novel. It has highlighted so many errors and I have managed to correct them. It has made me feel that much more confident in publishing my book.

As an editor, I would love it if this program could integrate track-changes to make it easier with authors. This extension works well with GoogleDocs to accomplish the same goal, although the extension runs a bit slowly and doesn't handle whole manuscripts deftly. I find it much easier to break chapters into separate documents to increase extension speed and responsiveness. It's a suitable work-around, but it's is kind of annoying to have to break out the chapters, and then recombine them.

I'm currently attempting to use the Chrome version instead because I could not get this to work in Google Docs. Linked my new account with a hotmail address to my Google address without realizing it was an issue until after it was installed. Attempted to use add-on in pre-existing docx doc but add-on menu doesn't even appear in there, so I copy pasted the entire document into the new project created which does have the add-on menu available. Try to run reports. Unknown error. Check website, seems there might be an issue because of the two email address, so I try to change the email address in Pro Writing Aid. System tells me there's already an account for that email, which I can only imagine must be because when I linked out to my google docs account, it created one for me because I've never tried this before. So I delete the new account I created, and then attempt to use the account setup with my gmail, but it still just gives unknown error. I copy-pasted it into the browser version as that seems to work, but I'm uninstalling this.

What a relief! And a huge improvement on the old ProWriting Aid in Google Docs. I've waited on this improvement for a long time. The only thing I wish for is an option to apply changes without closing so I can be sure I don't do something stupid and lose the work I did. But otherwise, outstanding. Thank you, Chris Banks.

Perfect for google docs. Make sure you Ctrl+A your text before going through the grammar check otherwise it won't work.

This is super nice, and as limited as machine help can be I think this add-ons work as well as it can be. It helps that ProWritingAdd don't make browser lag for every little thing like other program did to me.

I had just left a four star review before before I found out it was messing up my document. The add-on randomized the letters after every edit it made. Now I gotta go back and fix it all. I'll try ProWritingAid in the future AFTER the beta. EDIT: seems to be all good now!

It seems very easy to use and has great suggestions. I have an editor overseeing my writings but using this tool will help me with making the process easier for him and also improves my understandings of grammar and style of content as a whole.

So far this has helped me with some great suggestions that were missed by other checks.
