Copilot Chat vs Microsoft 365 Copilot: What's the Difference?
Copilot Chat is free with Microsoft 365. It can search the web, analyse uploaded files, and help with writing - but it has no access to your emails, Teams meetings, SharePoint documents, or calendar. Microsoft 365 Copilot costs A$47.90 per user per month and connects directly to your Microsoft 365 data: it summarises email threads, recaps meetings you missed, finds documents in SharePoint, and drafts responses using the context of real conversations. The paid version is not an incremental upgrade - it is a fundamentally different product. If your staff are copy-pasting emails into Copilot to get summaries, that is the signal the paid version is worth evaluating.
Copilot Chat: what is included for free
Copilot Chat (previously called Microsoft Copilot, and before that Bing Chat Enterprise) is a web-grounded AI assistant included with Microsoft 365 commercial subscriptions. It uses GPT-4 class models and can search the web, analyse uploaded files, and generate content - but it does not have access to your Microsoft 365 environment.
When a user asks Copilot Chat to summarise their emails from last week, it cannot do it. It has no connection to Exchange. When a user asks it to summarise a Teams meeting, it cannot do it unless the user manually pastes in a transcript. When a user asks it to find a specific SharePoint document, it cannot search SharePoint.
What Copilot Chat can do: answer questions using web search, draft documents and emails when the user provides the content, analyse uploaded files (PDFs, spreadsheets, images), and assist with coding, research, and general writing tasks.
Microsoft 365 Copilot: what the paid add-on adds
Microsoft 365 Copilot connects to your Microsoft 365 environment via the Microsoft Graph. This gives it access to your email, calendar, Teams meetings (transcripts and summaries), SharePoint documents, OneDrive files, and data from connected apps. The paid add-on unlocks Copilot capabilities within the Microsoft 365 applications themselves.
Copilot Chat vs Microsoft 365 Copilot

The practical difference in daily use
The clearest demonstration of the difference is in Teams meetings. With Copilot Chat, a user who missed a meeting can do nothing useful in Copilot unless someone pastes them the transcript. With Microsoft 365 Copilot, they open Teams, navigate to the meeting, and ask 'what did we decide about the project timeline?' and receive a specific answer drawn from the meeting transcript.
In Outlook, Copilot Chat can help draft an email if the user tells it the context. Microsoft 365 Copilot can summarise a 40-email thread the user has not read, identify the outstanding questions, and draft a response that references the thread - without the user reading any of it.
In Word, Copilot Chat can help write a document if the user describes what they want. Microsoft 365 Copilot can create a first draft of a client proposal based on previous proposals in SharePoint and the meeting notes from Teams.
When Copilot Chat is enough
Copilot Chat is genuinely useful for a class of tasks that do not require Microsoft 365 data access: writing assistance, research, document analysis when files can be uploaded, coding assistance, and brainstorming. For a business that primarily uses Microsoft 365 for email and file storage without deep Teams or SharePoint workflows, the free tier may deliver most of the AI productivity value at no incremental cost.
The assessment is straightforward: if the tasks where AI assistance would be most valuable are tasks that involve your Microsoft 365 data (email threads, meeting follow-up, SharePoint document retrieval), the paid Copilot is worth evaluating. If the valuable tasks are general writing, research, and document drafting where the user provides the content, Copilot Chat is sufficient.
Many small businesses have been using Copilot Chat for months without realising it is the free version - or without realising there is a paid version that accesses their Microsoft 365 data. If your staff are regularly copy-pasting email content into Copilot to get summaries or drafts, that workflow is a signal that the Microsoft 365 Copilot add-on would eliminate the manual step and deliver more value.
Requirements for Microsoft 365 Copilot
The paid Copilot add-on requires a qualifying base licence: Microsoft 365 Business Premium, E3, or E5. Users on Business Basic or Business Standard cannot be assigned Copilot - a plan upgrade is required first.
Microsoft also recommends addressing SharePoint permissions and data governance before deploying Copilot, as the product surfaces content from across the environment based on existing permissions. Oversharing that is invisible day-to-day becomes visible when Copilot retrieves it in response to queries.
