Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
