Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier if you already pay Gemini. B-tier standalone.S-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.
