Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.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 for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
