  • Can be slow on large corpora
  • File size limits
  • Can hallucinate on messy data
Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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 study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
