The short answer
Microsoft 365 Copilot is an AI layer across Microsoft's work suite. It uses Microsoft Graph and works inside Teams, Outlook, Word, Excel, PowerPoint, SharePoint, and the Microsoft 365 Copilot app. Organizations can also create and govern agents. Nema is designed for companies whose shared operating work happens in Slack.
Choose Microsoft 365 Copilot when Microsoft 365 is the main source of documents, communication, meetings, and identity. Choose Nema when Slack channels should own the coworker relationship and teams want model choice and channel-specific setup.

A leadership meeting brief
A chief of staff needs a meeting brief from approved project updates, recent decisions, and a supplied metrics packet. The result should identify unresolved decisions and propose an agenda without inventing a status.
With Nema, the leadership channel keeps the briefing instructions, recurring schedule, and approvers. Nema drafts the brief in Slack, cites the supplied or connected sources, and asks about missing owners. The chief of staff reviews the proposed agenda in the thread. The channel can retain corrections for next week's brief.
Microsoft 365 Copilot can ground the same job in emails, meetings, files, calendars, Teams conversations, and organizational relationships available through Microsoft Graph and Work IQ. It can draft or update work in the Microsoft applications where that content already lives. For a Microsoft-centered company, that depth can be more useful than moving context into Slack.
Choose Nema when
Choose Nema when Slack is the shared workplace and teams want one visibly configured coworker per channel. Nema can apply different instructions, tools, model choices, and approvers to leadership, operations, and customer channels.
This fit is strongest when the company does not want its AI work anchored to Microsoft 365 licensing or Teams. Verify each needed connector and action rather than assuming general catalog access covers it.
Choose Microsoft 365 Copilot when
Choose Microsoft 365 Copilot when the organization relies on Outlook, Teams, SharePoint, OneDrive, and Office documents. Copilot can work inside those applications and use the user's Microsoft 365 permissions. Microsoft's agents can be built with low-code or professional tools and distributed through the organization.
Microsoft also has the stronger documented governance stack for large Microsoft tenants, including Entra identity, Purview controls, administration, and agent lifecycle options. Licensing varies by plan and capability, so compare the exact Copilot edition and agent usage model.
Do not compare product names alone
Microsoft now offers Copilot Chat, Microsoft 365 Copilot, agents, Copilot Studio, and other products. Define which license and experience the evaluation includes. Some capabilities use metered billing, some require a Microsoft 365 Copilot license, and availability can vary by tenant.
Run the same brief in the actual applications the team uses. Check source permissions, citations, scheduled behavior, proposed actions, and the final work record. The meaningful comparison is Slack-centered work against Microsoft-centered work.
Common questions
Does Microsoft 365 Copilot work in Slack?
Microsoft's core Copilot experience is centered on Microsoft 365 and Teams. Current Microsoft Copilot Studio documentation should be checked for publishing-channel support because availability changes. Nema uses Slack as its primary interface.
Can both products build specialized agents?
Yes. Nema configures coworkers and custom agents for channel work. Microsoft supports declarative and custom agents through Agent Builder, Copilot Studio, and developer tools.
Which has stronger document context?
Microsoft 365 Copilot has a clear advantage when the organization's working set is already in SharePoint, OneDrive, Outlook, Teams, and Office. Nema can work with permitted connected sources, but it is centered on Slack collaboration rather than Microsoft Graph.
