Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
