Kai's verdict	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	A-tier. Genuinely different vibe from Suno — worth trying both for a month.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
