Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
