Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for local inference. If you care about privacy or want to tinker, install this today.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
