It's a good app. Helps with spelling errors and whatnot. Only gripe? You get two clarity corrections for free. Afterwards, you have to subscribe to get those. I remember when Grammarly let you have clarity corrections for free with spellchecking. The only thing you had to subscribe for was the VIP rephrase or restructuring. Miss those days, but the economy demands what it demands... Still a good app, wished it did large documents without issue.

Thanks for trying Grammarly for Android! We recently updated the generative AI experience, including changes to prompt limits. We understand this may feel like a significant shift. We’d also like to look into the issues you’re experiencing with large documents. Our Support team can help investigate at https://gram.ly/3vQJV2L.

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! 🏆 👍 😊 My friend was impressed when editing an official document to the council too. 👍

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.
