  • Smaller capability gap vs frontier models
  • Less polished UX
  • Not a full Excel replacement for heavy users
  • Integrations best on paid tiers
  • Overwhelming for beginners
  • Hosted inference pricing varies
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.)B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier infrastructure. The one platform every AI dev eventually uses.
