💡 Our Take

Choose Gemini in Looker if you operate in the Google Cloud ecosystem and want governance enforced by a code-first LookML semantic layer. Choose Power BI Copilot if your stack is Microsoft 365/Azure, your analysts live in Excel, and you want the broadest self-service adoption — Power BI Copilot generally has wider seat coverage at lower per-user cost.

Gemini in Looker - Pros & Cons

Pros

✓Grounded in Looker's governed semantic layer (LookML), which reduces hallucinations and respects existing access controls and metric definitions
✓Six distinct AI assistants cover the full BI workflow from data exploration to slide generation, more comprehensive than most competing BI Copilots
✓Tight integration with BigQuery and the broader Google Cloud data stack makes it a natural fit for existing GCP customers
✓LookML Code Assistant accelerates developer productivity by generating semantic model code from natural language prompts
✓Automatic Slide Generation directly exports dashboard content to Google Slides, useful for executive reporting workflows
✓Available across multiple languages including English, Spanish, French, German, Japanese, Korean, and Portuguese for global teams

Cons

✗Requires an existing Looker license plus a separate Gemini in Looker add-on, layering enterprise costs on top of Google Cloud spend
✗Quality of AI responses depends heavily on the quality of LookML modeling — poorly modeled instances will produce poor results
✗Locked to the Looker ecosystem, so teams using Tableau, Power BI, or other BI platforms cannot benefit
✗Some features remain in preview or limited availability, with capabilities and regions rolling out gradually
✗Public pricing is not transparently listed; customers must contact Google Cloud sales for licensing quotes

Power BI Copilot - Pros & Cons

Pros

✓Deeply integrated with Power BI Desktop, the Power BI service, and Microsoft Fabric, eliminating the need for a separate AI tool
✓Can generate an entire report page from a semantic model in seconds, dramatically reducing time-to-first-report
✓Respects existing row-level security, sensitivity labels, and Microsoft Purview governance, so enterprise compliance is preserved
✓Generates DAX formulas and explains existing measures, helpful for analysts who are not DAX experts
✓Built on Azure OpenAI with Microsoft's enterprise data protection — prompts and data are not used to train foundation models
✓Available across Power BI Desktop, web service, mobile, and embedded scenarios for a consistent experience

Cons

✗Requires a Microsoft Fabric F64 or Power BI Premium P1 capacity, which starts around $5,000/month — out of reach for small teams
✗Quality of output depends heavily on how well the semantic model is documented; poorly named tables and columns produce poor results
✗Limited to data already modeled in Power BI semantic models — cannot directly query raw files or arbitrary databases
✗Some features remain in preview and behavior can change between monthly Power BI releases
✗Geographic and tenant restrictions apply: Copilot is only available in supported Fabric regions and must be explicitly enabled by a tenant admin
