Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
