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 multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
