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 for academic research. Nothing else comes close for systematic reviews.B-tier. Still early. Manus is more flexible for less money.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
