  • Searches 125M+ papers
  • Extracts + synthesizes findings across papers
  • Systematic review workflow
  • Best text rendering in the game
  • Strong free tier

Weaknesses
  • Still pre-launch / beta — zero proven track record and no public pricing yet
  • iPhone-only by design, which immediately locks out half the smartphone market
  • Battery drain and privacy concerns from constant ambient context scanning are real and unresolved
  • Academic-only
  • Can hallucinate citations — verify everything
  • Aesthetic ceiling below Midjourney
  • Less style variety
  • Same copyright gray zone as Suno
  • Ecosystem smaller
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 academic research. Nothing else comes close for systematic reviews.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
