About Owlbert

Owlbert is a marketing science evidence server. It gives your AI assistant empirical laws of growth, and a verified NBD-Dirichlet model, so answers to marketing questions come from the evidence rather than the model's general training.

Who can use it

Access is by invitation: Owlbert adds you to its member list and sends you a personal setup page. There is no self-registration. To ask about membership, email bill.page@marketingscience.info.

How to connect

Owlbert works with any AI assistant that accepts MCP connectors: Claude, ChatGPT, Microsoft Copilot, Gemini Enterprise and Grok.

  1. In your assistant, add a custom connector with the server address https://heyowlbert.com/mcp. Nothing else needs filling in: the assistant reads Owlbert's sign-in settings itself.
  2. Click Connect. Owlbert's sign-in page opens. Sign in with the email and access token from your setup page, or with Microsoft if your organisation has set that up.
  3. Start a new chat and ask a marketing question. Your assistant calls Owlbert's tools and cites Owlbert's laws and reports.

Your setup page has click-by-click steps for each assistant. IT departments rolling Owlbert out in Microsoft 365 Copilot can ask for the Copilot admin guide.

How the evidence is graded

Every law card carries a grade from Owlbert's researchers, never from a model.

For IT departments and reviewers: what the tools do

Every tool reads; flag_research_question writes the one record you asked for. Owlbert speaks the Model Context Protocol over HTTPS with OAuth 2.1 sign-in.
