Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
