Both share in one click. A notebook has a share button at the top, and an agent shares from its three dots menu. You can only share with people inside your own organisation, not with anyone outside it.

How can I get AI to work with lots of PDFs at once?
Stop uploading and start pointing. A chat caps uploads because it recalculates everything on every message, while a Copilot notebook processes documents once, so it holds far more. In testing, a notebook took 52 PDFs without complaint. You can also build an agent that reads a OneDrive folder.
Can a Copilot Page work only from a set of Documents?
No, Pages are for working on a document with Copilot, not for holding sources. To ground Copilot in a fixed set of documents, build an agent, which you can even create from a page, or use a notebook, which is the hub for all the sources of one piece of work.
Can AI connect two Apps automatically?
Yes, but you often do not need generative AI for it. For personal apps, no-code tools like Zapier, Make or N8N connect two apps without code, and at work you use what your organisation approves, usually Power Automate. Check first for a native integration, because many apps already sync with each other.
