Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier. If you're on Vercel/shadcn, this is cheating.
