Sources worth feeding Gemini Notebook

A notebook is only as good as what you put in it. Every entry below has a copy-ready link — paste it straight into Gemini Notebook's Add source dialog — plus a tip on the cleanest import route for that kind of material.

  1. 1Copy a link. Use the Copy link button on any source below.
  2. 2Open Add source. In your notebook: Add source → Website (or Link).
  3. 3Paste and confirm. You can paste several links at once — one per line.

Academic papers

Gemini Notebook reads the text of the page you give it. Paste pages that carry the full text (an arXiv abs page, a PubMed Central article) — a paywalled landing page imports as just an abstract.
