There's a premium subscription plan for more serious use cases that provides suggestions on more advanced grammatical issues, tone detection, word choice, fluency, and more. The free version of Grammarly Keyboard gets the job done for casual usage. Grammarly’s dead-accurate grammar and spell checker will catch most, if not all, of your embarrassing mistakes while also showing you the correct form and usage, so you learn from it and hopefully don’t repeat them. You shouldn't be using this keyboard if you care about those things because Grammarly is all about language and grammar above anything else. Sure, it’s not the most feature-packed keyboard out there, and you'll miss out on some things like stickers, GIFs, themes, and more. The KeyboardKit library provides a SystemKeyboard that mimics the default iOS keyboard.

The Grammarly Keyboard is essentially a keyboard version of that, so you can avoid sending messages with awkward typos and errors. What I want to do is to replace the AutocompleteToolbar area of the keyboard with a custom button of my choice. Grammarly is a popular service that probably already exists as an extension in our PC browser to keep your writing free from grammatical errors and spelling mistakes.
