| Kai's verdict | A genuinely interesting evolution of video search that could make YouTube feel more like a knowledge engine, but it's still early-stage, US-locked, and paywalled behind Premium — watch this space rather than rerouting your workflow around it yet. (Verdict pending Phi's full review.) | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
