I've been using Grammarly for checking my grammar and spelling for years now, as I've always struggled with grammar. I'm not so fussed on the keyboard, but tbf I've not used it enough for it to learn my style, so I use the No. 1 SwiftKey for writing and then Grammarly offers corrections and whole sentence rewrites as I type. It's flipping amazing, and worth every penny (for me anyway) for the pro version! šŸ† šŸ‘ 😊 My friend was impressed when editing an official document to the council too. šŸ‘

I've been using Grammarly since 2014 in secondary school. It's a very useful tool, but the £129 subscription for premium is quite a lot, especially when you write an essay or research. It often glitches out and puts commas and semicolons into words, it also messes up the words trying to correct the spelling, for example: grandiloquent (if spelt wrong) turns into grand;iloquent or grandilograndiquent. I'm giving four stars only because it was a nice Chrome extension and somewhat good on my phone.

Please work 😭😭😭. When it does, it's the best one, but I couldn't use it anymore as it got so bad, almost every feature stopped working. I try everything: restarted phone, unistall it and install it agai. i tried others, but I can't find one that I like. Grammarly has the floating G that I can check instantly. It suggests the grammatically correct word in the text while I am writing but won't change it unless I choose to. AI analyzes hundreds of words together, other apps just a few dozen.
