What is the difference between Copilot online and Copilot within Teams?

Question

I'm just wanting to know what is the operational difference between Copilot online and Copilot within Teams?

Answer 1

Copilot online and Copilot within Teams use the same underlying Microsoft 365 Copilot capabilities but are optimized for different contexts and data scopes.

Copilot online (Microsoft 365 Copilot in the browser/portal)

• Acts as a general-purpose AI assistant across Microsoft 365.
• Can access data across the Microsoft 365 Graph (for example, documents, emails, calendar, and other content the user has access to) when used in the dedicated Copilot experience.
• Is not tied to a single Teams chat, channel, or meeting; it is designed for broader work scenarios such as drafting, summarizing, or querying information across apps.

Copilot within Teams Copilot is embedded directly into Teams and behaves differently depending on where it is used:

1. Chats and channels
   • Works inside a specific chat or channel.
   • In chat scenarios, Copilot references only the chat where it is opened and, by default, only messages from the last 30 days from the most recent message.
   • It cannot summarize images, Loop components, or files shared in the chat.
   • In Teams, Copilot can summarize chat and channel conversations, highlight open questions and decisions, and help catch up on discussions.
   • Copilot in Teams chats can also use documents shared in the chat or stored in connected SharePoint sites, chat and channel history the user has access to, and optionally web search (if enabled by admins).
2. Meetings and calls
   • Copilot uses the meeting transcript in real time to answer questions about what is being said in the meeting.
   • It can provide custom summaries, key discussion points, action items, and insights into unanswered questions during and after meetings.
   • If there is no transcript, Copilot is limited to the meeting chat only.
   • Answers may be limited or slower in meetings over about two hours.
3. Compose in Teams
   • Copilot can rewrite and adjust Teams messages (tone, length, clarity) and apply custom tone, translation, or added context.

Key operational differences

• Scope of data: Copilot online is oriented to work across Microsoft 365 data, while Copilot in Teams is scoped to the current Teams context (specific chat, channel, or meeting transcript) plus the user’s accessible content as described.
• Entry point and UX: Copilot online is accessed via the Copilot/Microsoft 365 web experience; Copilot in Teams is accessed inside Teams chats, channels, and meetings (side panel, compose box, or meeting interface).
• Use cases: Copilot online is best for cross-app work (documents, emails, planning); Copilot in Teams is best for collaboration scenarios—catching up on chats/channels, summarizing meetings and calls, and composing or refining Teams messages.
