I used Grammarly for about 10 years before finally switching to LanguageTool. It wasn’t the easiest switch since I had become accustomed to Grammarly’s UI. I also couldn’t take anything away from Grammarly’s performance, which likely explains its popularity among many writers. There are several Grammarly alternatives, and I have used quite a few of them. However, after testing LanguageTool a couple of times, I realized that it’s equally a great tool. And as a cherry on top, this relatively new app also has a free version.
