can't get this much useful app for free

grammarly is good app

Very useful. Good features. It's not like the spelling checker, this Grammarly can detect other mistakes. I am learning through this. Thank you!

Great add-on; really helps weed out typos and other mistakes. Doesn't always recognize sentence structures but that's to be expected from a piece of software, especially a free one.

Four stars because I ended up disabling the add-on due to it significantly interfering with one of my most used websites. Grammarly somehow changed the font on that site, which caused aesthetic issues I did not want to deal with any longer.
