Microsoft is further expanding the so-called Copilot notebooks in OneNote and the Copilot app: Those who collect documents, email excerpts, or their own notes on a topic there can now listen to the entire content as a spoken summary with two AI voices.
This saves reading time on the go, but requires a paid Copilot license.
Copilot notebooks get an audible summary
According to Microsoft's own description, a Copilot notebook is a kind of digital collection folder: those who store Word files, PDFs, OneNote pages, or links to a project there can subsequently ask Copilot specific questions about this material.
The AI responds exclusively from the added sources, not from the entire mailbox, Teams history, or the open internet – this reduces the risk of incorrect answers. Newly added is the so-called audio overview: from the collected material, a spoken dialogue between two AI voices is created, explaining and contextualizing the content, similar to a short podcast episode.
Users select the format, voice, speaking style, and approximate length beforehand, and the creation only takes a few minutes. According to Microsoft, at least one reference file in the notebook is required, such as a Word document or a OneNote page.
The function works both in the standalone Microsoft 365 Copilot app and directly in OneNote, with both locations remaining automatically synchronized.
Listening on the go saves reading time in office life
For everyday work, this primarily means: knowledge can be absorbed on the side instead of being read on screen. An example: a caseworker collects all relevant documents before a client meeting – a price list, the last minutes, and two email threads – in a notebook and has a ten-minute audio overview created from it.
On the way to the meeting, she listens to the summary in the car or on the train instead of frantically flipping through all the documents shortly before. Similarly, the function can be used to prepare for an internal meeting when several reports or a long email chain need to be summarized in advance.
The Recap feature in Microsoft Teams, which automatically turns meetings into minutes afterward, already works comparably – but the notebook audio overview goes a step further and summarizes material that was never discussed in a meeting, such as offers or research notes.
It remains important: the audio overview summarizes and contextualizes but does not replace a careful personal review of important figures or commitments before a client conversation.
Paid license required, Mac follows only at the end of August
According to the official Microsoft help page, the audio overview is reserved exclusively for commercial Microsoft 365 users with a business, school, or university account (Entra ID); a free Microsoft account is not sufficient.
Copilot notebooks themselves are also open to personal subscriptions at the Microsoft 365 Personal, Family, or Premium tiers – but the audio overview stays locked there, according to Microsoft, and remains tied to a business, school, or university account.
The spoken summary is available in German, English, French, Spanish, Italian, Portuguese, Japanese, and Chinese, among others. To try out the function, proceed as follows:
- Open a Copilot notebook or create a new notebook with Copilot support in OneNote.
- Add at least one file or page as a reference, such as a Word document.
- In the Copilot app, select the "Audio Overview" section; in OneNote, take the route via "Quick Capture."
- Set format, voice, and approximate length.
- Tap "Generate Audio" and play or download the finished summary.
The notebook function is already available for Windows and the web; for OneNote on Mac, the global rollout, according to an announcement in the Microsoft 365 Message Center, will only begin at the end of August 2026 and is expected to be completed by early September – the same timeline applies everywhere, regardless of Germany or the EU.
It will be crucial whether employees actually use the time savings or leave the audio overview as an additional format next to the actual document. Unlike the podcast feature of the private Copilot app, which was discontinued on August 18, the notebook audio overview remains and is even being further developed – an indication that Microsoft rates the format as more worthwhile for business use than for private use.
Those who upload client or company data into a notebook should check internal guidelines for handling sensitive documents beforehand, as the content temporarily leaves its usual storage location.
