Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
