Gemini Notebook

Gemini Notebook is a personal assistant that answers only from the material you actually hand it. Instead of scouring the entire internet and acting like it knows everything, it actually reads the documents, articles, or notes you upload, and finds its answers only within them.

Here's an analogy: a typical AI chatbot is like a know-it-all who has read every book out there, so it sometimes mixes in things that aren't quite right. Gemini Notebook, on the other hand, is like a librarian who has read only the exact stack of materials you gave them. It won't make up stories from outside that material — it summarizes, answers questions, or organizes notes strictly based on what's inside.

That makes it especially useful when you dump a pile of papers, meeting notes, or multiple reports and ask it to pull out just the key points, or to spot where the documents contradict each other. Its answers are grounded on Google's Gemini models underneath.

1. Gather several documents or articles you want to summarize or analyze.
2. Upload those materials to Gemini Notebook.
3. Try asking something like "Summarize these materials in three sentences" or "Find any contradicting claims across these documents."
4. Trace back which part of the materials the answer came from to check its basis.
