Grammarly does make a few mistakes now and again but overall it has improved my writing.

Very Great! Thanks

Oh how i've missed you. I have been on XP for years and by the end grammerly wouldn't work on the firefox browser, but now I have a windows 10 machine and the first thing I did was to get my grammerly back.

Great extension and app. It really helps when writing paper, emails, etc. The one down side is that google drive is not supported. This is really inconvenient because you have to do a lot of copy and pasting back and forth between google and the app/website.
