| Kai's verdict | 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. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
