Copilot Chat vs. Microsoft 365 Copilot: What's Free, What's Premium—and Where Teams Premium Fits In

This is a quick comparison of Copilot Chat, Microsoft 365 Copilot (paid), and Teams Premium, to help you understand the different AI options available to Microsoft 365 customers.

Summary: Copilot Chat (free) gives you AI help grounded in web data and open documents. The paid Microsoft 365 Copilot unlocks full access to your work data—emails, meetings, files, and Teams chats—plus advanced agents and priority performance. Teams Premium adds AI-powered meeting features like intelligent recap, live translation, and speaker markers, but doesn’t include full Copilot capabilities.

🧠 Copilot Chat (Free with Microsoft 365)

Now included for free with most Microsoft 365 business and enterprise plans (Business Basic, Standard, Premium; E3/E5), Copilot Chat is your general-purpose AI assistant. It’s available in apps like Word, Excel, PowerPoint, Outlook, and Teams, and is safe to use.

Key features:

• Web-grounded responses: Answers based on public web data and general knowledge.
• Context-aware help: Can read your open document or email and assist with drafting, editing, and brainstorming.
• Basic agents: Supports limited task automation (e.g., summarising text, generating ideas).
• Enterprise-grade security: Your data stays within your Microsoft tenant.

Limitations: It cannot access your internal work data (emails, meetings, Teams chats, etc.) unless you manually paste or upload it.

💼 Microsoft 365 Copilot (Paid Add-On)

This is the full-featured version of Copilot, available as a per-user license (~£25–£30/month). It transforms Copilot Chat into a true work assistant.

What you unlock:

• Work-grounded intelligence: Copilot can access your emails, calendar, Teams chats, OneDrive/SharePoint files, and more—automatically and securely.
• Work/Web toggle: Lets you switch between public and internal data sources in Copilot Chat.
• Advanced agents: Includes powerful tools like Researcher and Analyst, plus custom agent support via Copilot Studio.
• Priority performance: Faster, more reliable responses during peak usage.

Use case example: Instead of copy-pasting an email thread, you can ask Copilot in Outlook to summarise it instantly—no manual input required. It can also find information across any email, document, chat, SharePoint site, etc. that you have access to.

🎥 Teams Premium: AI Features for Smarter Meetings

Teams Premium is a separate license (~£6–£7/month) focused on enhancing the meeting experience. It does not include full Copilot access, but it does offer several AI-powered features:

Included AI features:

• Intelligent meeting recap: Auto-generated summaries, action items, and chapters from shared content.
• AI-generated notes and tasks: Captures key points from Teams meetings and assigns follow-ups automatically.
• Speaker and topic markers: Lets you jump to relevant parts of the meeting recording.
• Live translation: Real-time caption translation in 40+ languages.

Limitations: You can’t interact with meeting transcripts via chat or ask follow-up questions like “What were the key objections raised?”—that’s reserved for Microsoft 365 Copilot.

Conclusion

Copilot Chat is a useful tool that’s safe to use for all users, and it’s great that this is now included for free with most Microsoft 365 plans.

However, if your workflow is document-heavy or spans multiple apps, the paid Microsoft 365 Copilot is a game-changer. The ability to seamlessly access your emails, calendar, meetings, and files without manual copy-pasting saves significant time.

Teams Premium adds meaningful AI enhancements to meetings without the full Copilot price tag—making it a smart option for organisations that rely heavily on Teams for collaboration but don’t need the full breadth of Microsoft 365 Copilot.
