Kai's verdictS-tier for speed. When latency is the product, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Still early. Manus is more flexible for less money.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
