Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
