Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
