Kai's verdictThe 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.)S-tier for solo + free. The best free option, hands down.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Still early. Manus is more flexible for less money.
