Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier if you already pay Gemini. B-tier standalone.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
