Export a chat
Notebook Clipper saves the chat of a notebook in Gemini Notebook (formerly NotebookLM) as one file, with every question and answer in order and a list of the sources the answers cite.
Export the chat
Click Export chat in the Chat panel header
The button sits left of Gemini Notebook’s own Configure notebook icon and shows Export chat when you hover it, and clicking it opens a menu with the formats.

Click Export as PDF or Export as Markdown
The file downloads, and an empty chat shows the message No chat messages to export instead.
