Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
