Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.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.S-tier for designers. The only one that takes vectors seriously.
