| Kai's verdict | 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.) | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. |
