| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | 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.) | A-tier for data teams. S-tier if you already live in SQL + Python. | B-tier. Still early. Manus is more flexible for less money. |
