Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for designers. The only one that takes vectors seriously.
