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 for designers. The only one that takes vectors seriously.S-tier for text-in-image. Use this for posters, Midjourney for art.
