| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | 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.) | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
