Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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.A-tier. S-tier if you self-host. The reason open-source image gen matters.
