Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Still early. Manus is more flexible for less money.S-tier. Category-defining UX. If you take notes in meetings, switch this week.
