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.S-tier for designers. The only one that takes vectors seriously.B-tier. Still early. Manus is more flexible for less money.
