  • Still rolling out
  • Less agentic than Cursor/Claude Code
  • Model quality varies
Kai's verdictA-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. No reason not to use it if you're on Figma. Not worth switching for.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
