Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.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.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
