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.A-tier. Best for teaching a kid to code in 2026.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
