Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
