| 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. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier inside Photoshop (Generative Fill). B-tier standalone. |
