Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier if you already pay Gemini. B-tier standalone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
