Kai's verdictA-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
