Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Still early. Manus is more flexible for less money.
