Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for solo + free. The best free option, hands down.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. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
