Kai's verdictS-tier for teachers. If you teach K-12, start here this week.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.S-tier in the agent category. The first one I'd give to a non-technical friend.
