Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Still early. Manus is more flexible for less money.
