Kai's verdictA-tier. No reason not to use it if you're on Figma. Not worth switching for.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
