Pricing	Free + $12-$15/mo Premium + team plans	Free + $20/mo Pro + $40/mo Business
Best for	Non-native English writers, business email, anyone who types a lot.	Developers. Non-developers who want to ship working code.
Strengths	Works in every browser/app Now has generative AI (GrammarlyGO) Tone detection + suggestions	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick

Kai's verdict	A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
