GrammarBot

Sending an email or finishing a document and not sure if your English grammar is quite right? GrammarBot is a macOS app that checks your English text and suggests a corrected version — catching misspelled words, typos, and grammar mistakes before they embarrass you.

What makes it different is that it runs entirely on a local AI model, meaning no internet connection required and no subscription fees. Your text stays on your device, your privacy stays protected, and you get instant grammar corrections whenever you need them. A simple, offline-first writing companion for anyone who writes in English on a Mac.
