  • No standalone value — entirely dependent on having a YouTube Premium subscription
  • Complexity ceiling
  • Can generate brittle code
Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for academic research. Nothing else comes close for systematic reviews.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 strongest 'no-code' AI builder right now. Great for founder MVPs.
