| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | 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. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
