  • Expensive at scale
  • Still needs post-editing
  • Can feel overwhelming for non-coders
  • Expensive at scale
  • Bot-joining model

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. Market leader with reason. Start here for serious video.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for solo + free. The best free option, hands down.
