| Kai's verdict | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | B-tier. Still early. Manus is more flexible for less money. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
