Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.	B-tier. Still early. Manus is more flexible for less money.
