Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-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.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
