Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for designer-led sites. S-tier if animations matter.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier for model-shopping. I use this for every prototype before committing.
