Kai's verdictS-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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
