OpenAI has provided ChatGPT with a new plugin on September 3, 2026 – a type of add-on that connects ChatGPT with another service – for Microsoft OneNote. Those who collect meeting notes, minutes, or project documents there can now directly ask ChatGPT about them. On the same day, a second plugin for the support service Zendesk was released.
ChatGPT now searches and supplements OneNote notes
After connecting with a Microsoft account, ChatGPT can be asked in natural language about the content of specific notebooks or pages. According to the official guide from OpenAI, the plugin can find and summarize notes, collect decisions and open tasks, as well as create new notes or supplement existing ones.
For the search, a prompt like “Find the open questions in my Project Apollo notes and summarize them” is sufficient. For writing, a sentence like “Attach these meeting decisions to the homepage of Project Apollo” is enough. For each result, ChatGPT provides a link to the respective OneNote page, allowing for direct verification of the information.
A team assistant who manages an ongoing project notebook previously had to flip through all the pages from the last weeks for the status report to extract open points. With the plugin, a sentence to ChatGPT, such as “List all open tasks from the notes of the last four weeks,” is enough – the AI searches the connected pages and delivers a sorted list of findings.
How to connect ChatGPT with your notebook
The setup is done through the plugin directory in ChatGPT and takes only a few steps, without the need for an IT department to install anything in advance:
- Open the “Plugins” menu in ChatGPT.
- Select the OpenAI-owned OneNote plugin and start the connection.
- Sign in with the Microsoft account that has access to the desired notebooks.
- Confirm access to the appropriate notebooks or sections.
- Ask directly in the chat for content or have notes supplemented.
Which notebooks can be connected depends on the Microsoft permissions. Personal notebooks can only be accessed through the user’s own connected account. A connection with read-only access cannot create or modify notes – a separate sharing is required for that. Those who already use Copilot in OneNote, for example for read-aloud audio summaries, can use both tools in parallel – they access the same notebooks independently of each other. The connection remains until it is disconnected in the ChatGPT account; signing in again for every request is not necessary.
Availability depends on the plan and company settings
The plugin directory is visible in every ChatGPT plan, from Free to Plus, Pro, Business, and Enterprise. Whether a plugin can actually be used depends on the user’s plan, the region, and – in company accounts – the settings of the administrator. According to several trade media, apps are usually enabled by default for business accounts, while enterprise accounts need an administrator to activate them first; this has not been independently confirmed.
The plugin itself does not add extra costs, since it runs on the existing ChatGPT subscription. Those who already connect ChatGPT with a Google account know the principle from the connection to Google Drive files: there, too, access runs through a one-time account connection. For customer service teams, the concurrently launched Zendesk plugin is also worthwhile: it retrieves support tickets and the history of individual customers and helps prepare responses.
What will matter is how reliably ChatGPT distinguishes between similarly named notebooks when writing to them – a misfiled paragraph can easily go unnoticed in a shared notebook. It also remains to be seen how quickly approval happens in larger companies, where IT departments must first review each new connection. Anyone who keeps customer or personnel data in OneNote should check internal rules on handling sensitive data before connecting ChatGPT, since the AI can then access that content.
