Kai's verdictB-tier. Still early. Manus is more flexible for less money.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for speed. When latency is the product, start here.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
