Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for speed. When latency is the product, start here.B-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.
