Copilot in OneNote

OneNote is where a lot of an organisation's real knowledge lives — the meeting notes, the half-finished plans, the project notebooks nobody indexed — and it was also one of the last Office apps to get a full Copilot. It has one now. Copilot in OneNote does the things you'd expect (summarise, draft, rewrite, chat about the notebook) with some OneNote-specific strengths and a few limitations that come from the shape of the app itself. This guide is the honest tour.

What it does

Copilot lives in a pane on the right and reads the current page, section, or notebook depending on how you scope the prompt. The core operations:

Summarise. "Summarise this page" is the obvious one; "summarise this section" is the useful one. A section of a term's worth of weekly meeting notes becomes a page of decisions and themes. Copilot handles OneNote's loose structure — headings, checkboxes, tables, pasted email — better than you'd fear, and it does reasonable work on ink that OneNote has already recognised as text.

Draft and rewrite. Select notes and ask for a plan, an email, a set of talking points, or a cleaned-up version of scrappy bullets. This is where OneNote's role as the messy first draft pays off: the messy draft is already there, and Copilot's job is to make it presentable.

Extract to-dos. "List the action items on this page" pulls out tasks, and Copilot can insert them as OneNote to-do tags on the page. It doesn't create Planner or To Do tasks directly from OneNote — that's still a manual step, or one for the Teams Facilitator agent in a meeting.

Chat across the notebook. "When did we last discuss the vendor contract?" or "what did we decide about the office move?" searches the notebook's content and answers with references to the pages it used. For a personal or team notebook that's been going for a year, this is the feature that changes how people use it — the notebook becomes queryable rather than a place notes go to die.

Group and organise. Copilot can propose a structure for a page or a set of notes ("organise these notes by theme"), which is genuinely handy for a brain-dump page. It won't reorganise your section hierarchy for you; it works within a page or produces a new one.

Meeting notes and transcripts

This is where expectations need adjusting. OneNote has long been able to link a page to an Outlook meeting (meeting details, attendees, and a link back to the invite). What it does not do is pull in the Teams transcript or the intelligent recap. Meeting transcripts and AI recap live in Teams; collaborative meeting notes live in Loop (a .loop file in OneDrive), and Teams' newer Facilitator agent writes to Loop, not OneNote.

So the realistic workflow for someone who wants meeting knowledge in OneNote is: take notes in OneNote during or after the meeting, then ask Copilot in OneNote to tidy them — or copy the recap summary from Teams into the OneNote page. Copilot in OneNote can summarise a transcript you've pasted in, and it can use meeting details on a linked page as context, but it isn't an integration. Microsoft has talked about bringing more of the Teams meeting artefacts into OneNote (and about Copilot Notebooks surfacing in OneNote); treat that as roadmap, and check the current state before promising it.

Clients

Copilot in OneNote is available in OneNote for Windows (the desktop app, not the retired Windows 10 store app), OneNote for Mac, OneNote on the web, and the iOS/iPad app; the Android app trailed the others. The retired OneNote for Windows 10 app never got Copilot, which matters because a surprising number of users still have it pinned — the "Copilot doesn't appear in my OneNote" ticket is often that. Push everyone to the current OneNote desktop app first.

Notebooks must be stored in OneDrive or SharePoint for Copilot to read them. Local notebooks (still possible on Windows) and notebooks on a legacy file share are invisible to Copilot, as are pages that haven't synced.

Licensing and controls

A Microsoft 365 Copilot licence is required; the free Copilot Chat surface doesn't operate inside OneNote. There's no OneNote-specific admin switch — Copilot in OneNote follows the tenant's Copilot settings and the licence assignment. Data access is the standard model: Copilot reads notebooks the user can already open, and notebooks are subject to the same SharePoint and OneDrive permissions, sensitivity labels, and retention as any other file. A shared team notebook that's been over-shared for years is just as much of a Copilot exposure as an over-shared document library; the Restricted Content Discovery controls apply to the sites that hold notebooks too.

Where it falls short

• Scope is coarse. Page, section, or notebook. There's no "these three pages" without copying them together.
• Ink. Handwriting that OneNote hasn't converted is largely opaque to Copilot. Convert ink to text first.
• Images and embedded files. A screenshot of a whiteboard is a picture; Copilot won't read the words in it from the OneNote pane. Embedded Office files are treated as attachments, not content.
• Very large notebooks. Chat across a notebook with thousands of pages gets slower and vaguer. Split by year or project.
• No cross-notebook chat. Copilot works in one notebook at a time. For "across everything I've written," the Microsoft 365 Copilot app's chat (which searches OneNote content via Microsoft Graph) is the better tool.

The practical pitch

For individuals: your notebook is now searchable in plain language, and your scrappy notes become a clean summary in one prompt. For teams: the shared project notebook finally pays back the effort of keeping it. For admins: nothing new to configure beyond Copilot itself — but a reason to retire the Windows 10 app and to look at who can see the notebooks that have quietly accumulated for a decade.
