Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
