Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-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 for local inference. If you care about privacy or want to tinker, install this today.
