Microsoft

Vendor

Productivity assistant tightly integrated with Microsoft 365, Graph, and enterprise workflow data.

Curated by Tiberiu ArvaStale

Proprietary
DocsWebsite

Strengths

  • Deepest M365 integration
  • Graph data access
  • Enterprise assistant packaging

Practitioner note

Natural fit when the real value is inside Microsoft 365 workflows and Graph-connected knowledge, not just generic chat over documents. Uses the shared Microsoft Copilot visual identity rather than a separate M365-specific product mark.
