Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Still early. Manus is more flexible for less money.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
