How do I summarize multiple sources on one topic with Copilot?

Name the topic and specify the sources explicitly — meeting, document, presentation. Ask for the result as a table with a reference column so every statement is tied to a source.

What makes a good Copilot summary?

Three layers: the core, the open points, the next step. Without the third layer, you only have a shorter version of the problem.

Can I trust Copilot's summaries?

Trust the structure, verify the details. For anything you pass on, open the referenced source — especially when Copilot summarizes across multiple documents.

Which sources can Copilot summarize?

Anything it can reach in your work environment: documents, mails, chats, meeting transcripts. What lives outside or was only discussed verbally, it doesn't know.

When does this exercise pay off most?

Whenever a topic is spread across several places and someone asks you for the status. That's exactly when the reference table saves the most — it replaces jumping between five windows.

Goal

You turn the information flood from mails, chats and documents into a summary you can work with.

Why this matters

You know the moment: you jump between mail, chat and document — just to get an overview. The information exists. It’s just spread across five places, and none of them tells the whole story.

Summarizing isn’t wasted time. It’s focus gained — and with Copilot, a matter of minutes.

The drill

Open a document, a Teams chat or a note with lots of information.
Open Copilot.
Use this prompt:

Summarize the following information for me:
What is the core of the content?
Which open points or tasks follow from it?
What should I do next?

The third question is the most important one. A summary without a “what now?” is just a shorter version of the problem.

Extra round

Usually there’s more than one source on a topic. Have Copilot build a complete picture:

Create a comprehensive overview of [topic]. Use the following
sources: /[meeting], /[Word document], /[presentation].
Deliver the relevant answers in a table and add a second column with
the reference to the corresponding document.

The reference column is the trick: you see not only what holds, but where it’s written — and can verify any statement in seconds.

Micro-win

Today you connected content — you didn’t just open tools.

Remember

Seeing connections is a skill, and Copilot is a tool for it, not the truth. For anything you pass on: open the reference, check the statement. Especially with syntheses across multiple sources.
