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.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
