Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for designers. The only one that takes vectors seriously.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for builders. The right primitives. What Kai is built on under the hood.
