Kai's verdictA-tier in its niche. The only one that actually gets emotion right.B-tier. Still early. Manus is more flexible for less money.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.
