Feature overview
The new Copilot Notebooks design in the Microsoft 365 Copilot app for DoD, GCC, and GCC High clouds now lets users organize related chats, output creations, and references into a persistent AI workspace. Copilot uses the Notebook's accumulated context to ground responses, so work continues across sessions instead of starting over each time. While this is the quicker, light-weight Notebooks experience, you can still find the workspace-forward experience in OneNote.
