  • Less agentic than Cursor/Claude Code
  • Model quality varies
  • Writing quality trails Claude
  • Over-refusals on edge content
  • UI is cluttered
Kai's verdictS-tier for teachers. If you teach K-12, start here this week.The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.)B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
