Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
