Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.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.
