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.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
