Kai's verdictB-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 for creators training custom looks. B-tier for general use.B-tier. Still early. Manus is more flexible for less money.
