Merge Notebooks

Merge Notebooks copies the sources of several Gemini Notebook (formerly NotebookLM) notebooks into one new notebook. Chats and summaries do not come along. You can choose to delete the originals after the merge.

Why merge notebooks?​

You may have three notebooks about the same topic. In one notebook, Gemini Notebook can answer using everything at once.

How to merge​

  1. Click Merge Notebooks in the sidebar.
  2. Type a name in New Notebook Name.
  3. Tick the notebooks to merge. Use Search Notebooks to find them.
  4. Tick Delete originals only if you want the old notebooks removed.
  5. Click Merge.

You can also tick notebooks in All Notebooks and click Merge in the bar.

Chats do not come along

Only the sources are copied. The chat history, the summaries and what Gemini Notebook understood about each source stay in the old notebooks.

Good to know​

  • Leave Delete originals unticked until you have checked the new notebook.
  • The Basic plan has 3 merges. Kortex Pro has no limit. When you reach the limit a window says so and offers Pro.

Should I merge or compare first?​

If you are not sure the notebooks overlap, use Compare Notebooks first. It shows the sources two notebooks share and the ones only one has. From there, Merge into New puts both into a new notebook. Compare needs Kortex Pro.
