  • Slow vs doing it yourself
  • Breaks on complex auth flows

Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier infrastructure. The one platform every AI dev eventually uses.The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.)B-tier. Still early. Manus is more flexible for less money.
