  • Less code quality than dedicated IDEs
  • Academic-only
  • Can hallucinate citations — verify everything
  • Still a limited test — US Premium subscribers only, with no firm global timeline
  • Raises real creator-traffic concerns: AI answers may reduce clicks to actual videos
  • No standalone value — entirely dependent on having a YouTube Premium subscription
  • Not a traditional NLE — some workflows awkward
  • Overdub ethics require care
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.)S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
