Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.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 solo + free. The best free option, hands down.
