Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
