The verdict
On the data we have, Microsoft 365 Copilot (PowerPoint) and Google NotebookLM are too close to call — it comes down to which strengths matter to you.
The two split 6 decided rows evenly; the rest depend on data still being collected.
Copilot lives inside real PowerPoint and your Microsoft 365 data — the enterprise pick, but it's a paid add-on on top of an M365 licence.
