Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.
