Kai's verdictS-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.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
