Kai's verdictA-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.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
