Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Still early. Manus is more flexible for less money.
