Copilot Notebooks explained: working smarter with more context in Microsoft Copilot

In this article we explain simply what Copilot Notebooks are, when to use them and how to get more out of them in practice.
What are Copilot Notebooks?
Microsoft Copilot is often used for quick questions. You ask something, get an answer and move on. That works fine for isolated tasks. But sometimes you need more. For example when you work on a project, meeting, analysis or document where multiple sources come together.
That is what Copilot Notebooks are for.
A Copilot Notebook is a workspace inside Microsoft Copilot where you gather all relevant information for one task or project. Think of files, Copilot Chats, Pages, meeting notes, links and other sources. Copilot then uses that collection to give more targeted answers [1].
So the key difference with a regular chat is: you build context first.
In a notebook you build context up front. You no longer have to explain what you are working on every time. You bring the right sources together and then ask questions about exactly that information. Microsoft describes this as a bounded workspace in which Copilot only uses the references you added [2].
Why are Copilot Notebooks useful?
The strength of a notebook is not "another place to chat". The strength is focus.
A regular Copilot Chat is handy for quick questions. But during longer work you quickly lose context. You have a document here, meeting notes there and maybe an earlier chat with good input. A Copilot Notebook brings that together in one place.
In practice that means: less copying and pasting, less searching for scattered documents and better answers because Copilot knows which sources belong to your task.
Notebooks are especially useful for work that isn't done in one go. Think of research, project preparation, client proposals, onboarding, meeting preparation or content creation.
How do Copilot Notebooks work?
It is simple: you create a notebook, add sources and then ask Copilot questions about those sources.
Step 1: Create a new notebook
Open Microsoft Copilot, go to Notebooks and choose New notebook. Give the notebook a name that matches one task or project. For example:
- "Preparation MT meeting Q3"
- "Research new service offering"
- "Content plan LinkedIn campaign"
- "Onboarding new employees"
- "Client proposal Project X"
Step 2: Add sources
Next you add sources. Microsoft supports Word, PowerPoint, Excel and PDF files, as well as Loop, Pages and OneNote pages [2].
There are multiple ways to add references:
- Search: type the name of a specific file. SharePoint sites, document libraries or folders can also be added as a reference. Copilot can then use supported files in that location.
- Upload: select the Upload button and find the file on your device.
- Link: add a link to documents in OneDrive or SharePoint. Links to content outside your organization are not supported.
- OneDrive: browse to a file or an entire folder in OneDrive and add it.
- Drag and drop: drag a file into the references area.
Important: a notebook does not automatically search your entire organization. Copilot only uses the sources you add and that you have access to. That makes answers more targeted, but it also means you need to think carefully about which sources you add [3].
Step 3: Ask Copilot questions
Once your sources are added, you can start asking questions. Copilot answers based on the content of your notebook [5].
Example prompts:
- "Summarize all sources and name the five most important themes."
- "Which risks are mentioned in these documents?"
- "Create an overview of the key decisions from the meeting notes."
- "Write a first draft of an advisory note based on these sources."
- "What information is still missing to make a good proposal?"
Step 4: Add extra context later
A notebook doesn't have to be complete right away. You can add extra documents, notes or meeting reports later. That way the notebook grows along with your project.
Step 5: Use instructions for better output
You can also set Copilot Instructions. These tell Copilot how to respond. For example short, business-like, in Dutch or only based on the sources in the notebook [4].
Setting instructions is easy: open the dropdown next to the notebook name, choose Copilot instructions, type your instructions and click Save. You can adjust them at any time.
For beginners something like this already helps a lot:
Respond briefly and practically. Only use the sources in this notebook. If information is missing, say so explicitly. Write in clear language for a business audience.
Copilot Notebooks vs regular Copilot Chat
A notebook does not replace Copilot Chat. It is a different way of working. Regular chat remains fine for quick questions, brainstorms or isolated tasks. A notebook is especially useful when multiple sources and longer context matter.
Copilot Chat is mainly useful for quick questions, brainstorms and short tasks. Copilot Notebooks are stronger when you work on one topic for longer and want to use multiple sources.
Copilot Chat can use web information. A notebook works with the sources you add [6].
Below is an overview of the key differences:
| Aspect | Regular Copilot Chat | Copilot Notebook |
|---|---|---|
| Best use | Quick questions, brainstorms, short tasks | Projects, research, recurring tasks with multiple sources |
| Grounding | Based on web data by default. Org content can be added via upload, slash command or in selected apps. | Exclusively based on the references you add to the notebook. |
| Web information | Copilot can use information from the internet. | No web grounding. Only your references. |
| Retaining context | Works within one conversation. A new conversation starts without earlier context. | Persistent workspace. You keep returning to the same notebook with the same sources. |
| Adding sources | Add files to individual prompts via upload or slash command. | Add references structurally (files, folders, SharePoint sites, Pages, OneNote pages). |
| Setting instructions | General custom instructions via settings. | Notebook-specific Copilot Instructions per notebook. |
| Collaboration | Sharing Pages or output. | Notebooks can be shared with colleagues. Instructions and references are then shared too. |
| Limitations | Depends on license and available features. | No image generation or data visualizations. No web grounding. Deletion is permanent. |
| Audio | Not standard in regular chat. | Audio overviews available for a spoken summary of your notebook. |
In short: use Copilot Chat for quick questions. Use Copilot Notebooks when you need more context, structure and your own sources.
Practical use cases for knowledge workers
1. Preparing research
Researching a new topic, market or client question? Put the key sources in a notebook and ask Copilot to name the common thread, opportunities, risks and open questions.
2. Preparing and following up meetings
For a meeting you can bring together agendas, previous minutes, relevant documents and open actions. Then ask Copilot for a short preparation with talking points and required decisions.
3. Creating drafts and proposals
For a client proposal, project plan or advisory note you can bring all sources together and let Copilot help with a first draft.
4. Organizing and tracking projects
In projects, information is often spread across documents, presentations, notes and meetings. A notebook offers one place you keep returning to for status, decisions, risks and next steps.
5. Creating content
For content creation you can collect earlier blogs, tone-of-voice documents, customer input and product information. Then let Copilot create a first draft based on those sources.
Mini example 1: doing research with a Copilot Notebook
Say you want to write an internal advisory note about a new topic. Create a notebook, add the key sources and work step by step.
Step 1: Create a notebook. Call it for example "Research AI policy 2026".
Step 2: Ask for an overview. Prompt: *Summarize the sources in a maximum of ten bullets. For each bullet, state which source the information comes from.*
Step 3: Ask for analysis. Prompt: *Which three themes recur most often? Which points are still unclear or insufficiently supported?*
Step 4: Create a first draft. Prompt: *Create a first advisory note of at most one page. Only use information from this notebook. If something is missing, put it under "Still to investigate".*
Mini example 2: preparing a meeting
Say you have a project meeting next week. Create a notebook with the previous minutes, project planning and open actions.
Step 1: Create a notebook. Call it "Project meeting preparation July".
Step 2: Ask for preparation. Prompt: *Create a meeting briefing. Give: 1. a short summary of the current status, 2. key progress, 3. open actions, 4. decisions needed, 5. three questions I should ask.*
Step 3: After the meeting: add meeting notes and ask for follow-up. Prompt: *Turn these meeting notes into action items with owner, deadline and dependencies. Also indicate which points are still unclear.*
This is exactly the kind of work where Notebooks make sense: multiple sources, recurring context and a need for structure.
When should you not use a Copilot Notebook?
A notebook is useful, but not always necessary. In the following situations regular Copilot Chat is often more logical.
1. You have a quick, standalone question. For a simple question like "make this sentence shorter", "give five title ideas" or "explain this concept", a notebook is overkill. Copilot Chat is designed to quickly ask questions, explore ideas and add context while you work [7].
2. You mainly need current web information. Copilot Notebooks don't use general web information. They work with the sources you add yourself. Do you mainly need current market information or news? Then regular Copilot Chat is usually more convenient [2].
3. You want to create images, charts or data visualizations.
4. You work with only one document. If you only want to summarize, edit or analyze a single document, you can often do that directly via Copilot Chat (for example by attaching the file to your prompt). A notebook becomes truly valuable once multiple sources matter together.
Best practices: getting the most out of Copilot Notebooks
1. Create one notebook per goal. Don't use one big catch-all notebook. Instead create one notebook per project, client, topic or deliverable. That keeps the context sharp.
2. Only add relevant sources. Ten good sources beat fifty mediocre ones. More sources does not automatically mean better answers. Start small and expand the notebook later.
3. Provide clear instructions. Examples: *Write in simple language. Use subheadings and bullets. Give the conclusion first. Only use the sources in this notebook. Always respond in a business-like and concise way. If information is missing, say so. Do not make assumptions.*
4. Ask for a summary first, analysis second. Don't start with "write a report". First ask:
- What is in these sources?
- Which themes recur?
- What is missing?
- Where are the contradictions?
Ask for a summary or analysis first. Only then let Copilot create a draft, proposal or action plan. That usually gives better output.
5. Let Copilot flag uncertainty. A good prompt is not just "give an answer". A better prompt is: *Answer based on the sources. If information is missing or uncertain, say so explicitly.* That makes output more usable, especially for policy, projects or client proposals.
6. Always check the output. Copilot helps with summarizing, structuring and writing, but it remains a tool. Always check the output, certainly for client communication, policy or sensitive information.
7. Don't use notebooks as an archive.
8. Share notebooks strategically.
9. Use audio overviews.
Conclusion: Copilot Notebooks make Copilot less scattered and more focused
Copilot Notebooks make Copilot more useful mainly because they hold on to context. Not by searching everything, but by putting the right sources together.
For quick questions, regular Copilot Chat remains fine. But if you work on research, meetings, projects or content with multiple sources, a notebook gives more grip.
The best way to start is small:
- Choose one concrete topic.
- Create one notebook.
- Add a few good sources.
- Set Copilot Instructions for tone and format.
- Ask for a summary and analysis first.
- Only then create a draft or action plan.
That way Copilot becomes less of a standalone chatbot and more of a workspace where you can organize, understand and use information better.
Fewer scattered prompts, more targeted context and more grip on your work.
