Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
