| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
