Kai's verdict	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. Close second to Cursor. If $5/mo matters, start here.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	B-tier. Still early. Manus is more flexible for less money.
