  • Raises real creator-traffic concerns: AI answers may reduce clicks to actual videos
  • No standalone value — entirely dependent on having a YouTube Premium subscription
  • Expensive at scale
  • Still needs post-editing
  • Not for full songs with vocals
  • Shorter generation limits
Kai's verdictS-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. Market leader with reason. Start here for serious video.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
