Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
