Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.B-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.
