Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
