đĄ Our Take
Choose Power BI Copilot if you already pay for Power BI Premium or Fabric and want AI baked into the same authoring tool your analysts use. Choose ThoughtSpot Sage if natural language search is your primary use case and you want a best-in-class search-driven analytics experience that works across multiple cloud data warehouses without requiring a Microsoft stack.
