Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier for open-source model APIs. The default in this space.
