Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.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.)B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
