Copilot v. Claude

Comparison of Microsoft 365 Copilot and Claude for Business AI: Rebecca from Maxsum Consulting led a comprehensive session comparing Microsoft 365 Copilot and Claude, focusing on their business-level subscriptions, integration, and use cases, with David supporting in the chat and attendees raising practical questions throughout.

• Business Subscription Focus: Rebecca clarified that the discussion was limited to business-level subscriptions, specifically the Microsoft 365 Copilot add-on and Claude Team or Enterprise seat licences, excluding personal or consumer-grade versions.
• Integration and Data Boundary: Microsoft 365 Copilot is designed to operate within the Microsoft 365 data boundary, leveraging organisational controls and access permissions, while Claude as a standalone tool requires manual upload or connector configuration to access organisational data, with native access limited to local device files.
• Model Availability and Functionality: Microsoft 365 Copilot acts as an orchestration layer, integrating both GPT and Anthropic Claude models, allowing users to select or auto-assign models for tasks, whereas standalone Claude only provides access to its own models, with Microsoft Copilot offering broader model options and integration across apps.
• Use Case Differentiation: Copilot excels in productivity tasks within the Microsoft 365 ecosystem, such as summarising meetings, extracting insights from files, and automating workflows, while Claude is preferred for large context analysis, technical problem solving, and code generation, especially for users with heavy development needs.
• Connector and Agent Capabilities: Copilot supports pre-built connectors and agent creation via Copilot Studio, enabling integration with third-party data sources and complex organisational agents, whereas Claude uses an open connector standard (MCP layer) and requires more technical steps to achieve similar agent functionality.

• Security, Privacy, and Data Governance Considerations: Rebecca emphasised the importance of understanding data boundaries, access permissions, and organisational policies when choosing between Copilot and Claude, highlighting the need for intentional decisions regarding who gets access and how sensitive data is handled.
  • Data Boundary and Access: Copilot keeps all data within the Microsoft 365 tenant boundary, only accessing information users are permitted to see, while Claude only accesses data explicitly shared by the user at the time, with no automatic cross-environment data sharing unless connectors are configured.
  • Training and Compliance: Both Copilot and Claude business subscriptions do not train their models on user data, but Rebecca advised due diligence based on compliance and regulatory requirements, recommending against consumer-grade tools for business use.
  • Acceptable Use and Policy Enforcement: Rebecca recommended organisations establish acceptable use policies for both tools, audit for unauthorised personal subscriptions, and ensure proper permissioning and review processes to maintain data security and compliance.
• Licensing, Billing, and Consumption Models: Rebecca provided a detailed breakdown of the licensing, billing, and consumption models for Copilot and Claude, explaining the differences in credits, tokens, allowances, and cost implications for business users.
  • Copilot Credits and Billing: Copilot add-on licence covers most day-to-day usage within Microsoft 365 apps, with credits only billed for external-facing agents or co-work features, requiring intentional opt-in for pay-as-you-go or prepaid credits.
  • Claude Token Allowance: Claude Team and Enterprise licences provide a token allowance per seat, with usage limits typically over a five-hour period; exceeding the allowance results in throttling or additional billing, with token costs generally lower than Copilot credits but stricter usage caps.
  • Scenario-Based Cost Comparison: Rebecca compared typical scenarios, such as Microsoft 365 Business Premium with Copilot add-on versus Claude Team licence, outlining monthly costs, included allowances, and overage billing, advising organisations to understand their usage patterns to estimate costs accurately.
• Practical Demonstrations and Feature Comparison: Rebecca demonstrated practical examples of using Copilot and Claude for document summarisation and spreadsheet analysis, highlighting differences in file access, model selection, and integration across Microsoft 365 apps.
  • Document Summarisation Workflow: Rebecca showed that Claude requires manual file upload from the local device for document analysis, while Copilot allows direct linking to files within Microsoft 365 cloud sources, maintaining data within the organisational boundary.
  • Model Selection in Copilot: Copilot users can select between quick response, think deeper, or specific models (GPT or Claude) for tasks, with auto-prompt functionality choosing the best model based on the request, offering flexibility and tailored outputs.
  • Spreadsheet Integration: Copilot integrates natively with Excel, enabling users to query, edit, and cross-reference files within the Microsoft 365 ecosystem, while Claude as an add-in is limited to the current file and cannot access other organisational files unless manually uploaded.
• Guidance for Organisational Decision-Making: Rebecca concluded with actionable guidance for organisations, recommending intentional selection of tools based on operational needs, data protection requirements, and role-specific use cases, and encouraged review and policy development.
  • Tool Selection Criteria: Rebecca advised organisations to choose Copilot if their operations are primarily within Microsoft 365, ensuring data stays within the ecosystem, while recommending Claude for users with heavy development or third-party integration needs.
  • Role-Based Licensing: Organisations may opt for selective licensing, providing Copilot or Claude access to specific users or roles based on their requirements, rather than blanket deployment, to optimise cost and functionality.
  • Policy and Review Process: Rebecca stressed the importance of establishing responsible AI guidelines, auditing for unauthorised tool usage, and regularly reviewing and adjusting access and policies to align with evolving organisational needs.
• Upcoming Sessions and Follow-Up Actions: Rebecca announced future webinars and in-person events focusing on deeper technical aspects and billing implications of Copilot and Claude, inviting attendees to review materials, provide feedback, and register for upcoming sessions.
  • Future Webinar Topics: Upcoming sessions will cover detailed use cases in email, Word, PowerPoint, and the co-work feature in both Copilot and Claude, with invitations to be sent to attendees.
  • Follow-Up and Support: Rebecca and David offered ongoing support, encouraging attendees to reach out with questions and to review the session recording and slides for further clarification.

Follow-up tasks:

• Follow-Up on Unanswered Questions: Review the chat for any questions not addressed during the session and follow up with attendees individually as needed. (David)
• Distribution of Webinar Materials: Send the recording and slide deck of the webinar to all participants for review and reference. (Rebecca)
• Audit of Personal AI Subscriptions: Audit the organisation for any personal or consumer-grade AI subscriptions being used by staff and ensure compliance with business policies. (Rebecca)
• Invitation to Upcoming Event: Send invitations to all webinar participants for the in-person event at Microsoft on 29th of the month, focusing on Co-Work features and billing implications. (Rebecca)
