Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for designers. The only one that takes vectors seriously.S-tier in the agent category. The first one I'd give to a non-technical friend.
