Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier for data teams. S-tier if you already live in SQL + Python.
