Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. Best for teaching a kid to code in 2026.
