Grammarly rides along everywhere you type — email, docs, browser, desktop apps — correcting grammar, adjusting tone, and now drafting and rewriting with AI. Its strength is being ambient: you don’t go to Grammarly, it comes to your writing.
It’s not the tool for generating long-form content from scratch, but as an always-on quality layer over everything you write, its free tier is excellent and Pro is a sensible upgrade for professionals.
