Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for open-source model APIs. The default in this space.
