| Kai's verdict | S-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 in the agent category. The first one I'd give to a non-technical friend. |
