In Copilot Chat, open Notebooks in the left-hand bar and choose to create a new one. Give it any name and press create. You can skip adding references and start with an empty notebook, then add files, links and instructions later.

Can I change a Copilot notebook's Instructions?
Yes. Open the notebook and rewrite its instructions yourself whenever you want. You do not need a new notebook, and everything else stays as it is. Save the old instructions as a Page first, so you can go back if needed.
Can I add Website links to a Copilot notebook?
Yes, notebook references now accept links to websites as well as files. That is useful for anything online that changes, such as academic or legal material, because the notebook works from the current published version rather than an old download.
Can a Copilot notebook reference a Recurring meeting?
No, a reference points at one specific past meeting, even in a recurring series. The workaround is to write in the notebook's custom instructions that it should summarise that meeting since last time. Then you just open the notebook and ask it to run.
