This new OneNote feature is so good that I stopped using everything else
Microsoft's Copilot Notebooks feature in OneNote transforms the app from a passive note storage tool into an active workspace. By integrating AI directly into OneNote, users can consolidate notes, Word documents, Excel spreadsheets, and PDFs into a single notebook and let Copilot surface patterns, summarize content, and generate actionable insights — without needing to manually upload files or switch between apps. The author finds this more useful than standalone AI chatbots because it fits naturally into the existing Microsoft 365 ecosystem. An upcoming mind maps feature is also highlighted as a promising addition.
