Chapter 6. Gemini Notebook — a research assistant of your own

Key points

• Gemini Notebook answers only from the material you gave it
• It is an outstanding fit for reading across several PDFs: literature reviews, conference preparation, in-house teaching
• Published material such as papers and guidelines is the safest and strongest use

Starting with the tool that lands hardest

The first tool in this practical part is Gemini Notebook, because it is the one most therapists immediately recognise as useful.

Gemini Notebook is a free AI tool from Google. Its defining feature is that

it answers only on the basis of the material you uploaded

Where ChatGPT and Claude answer from knowledge of the whole world, Gemini Notebook reads only what you gave it and answers from within that. Hand it papers or study-group material and it becomes, quite literally, a research assistant of your own. Because it answers only what is in the documents, hallucination is also less likely.

What it can do

Load several PDFs together, then ask:

• "Lay out what these papers have in common."
• "Compare these three studies and tabulate how their conclusions differ."
• "Explain the difficult parts of this chapter simply."
• "From this material, put together the key points for a study group."

There is also a feature that generates an audio overview — a podcast-style spoken summary — from several documents. You can revise papers by ear on the commute.

It lands hardest in

• literature reviews (reading across a large body of papers)
• conference preparation (extracting key points from several documents)
• in-house teaching (building study-group material)

which meshes exactly with a therapist's work of reading, summarising and teaching.

Free-tier limits (as of 2026)

The free tier goes a long way, but it has limits.

• 50 sources per notebook
• 50 chats per day
• 3 audio overviews per day

If you read large volumes of papers continuously for research, or want to lean on it every day, the paid tier (for individuals: 300 sources per notebook, 500+ chats a day) becomes an option. But the free tier is enough to start. It is a very well-finished tool.

Gemini Notebook and security — what to hold onto

Applying the Chapter 2 principles to Gemini Notebook:

• Uploaded material is stated not to be used to train Gemini Notebook's models.
• However, if you submit feedback, Google staff may review that content.
• So do not upload raw patient data. Work mainly with material that would be fine outside — papers, conference abstracts, published guidelines.
• If your organisation needs strict data protection and administrative controls, the paid tier via Google Workspace (where protection is contractually guaranteed) becomes an option.

Papers and guidelines are published information, which makes them Gemini Notebook's strongest and safest ground. Start there.

Try this

Go to Gemini Notebook (notebooklm.google.com) and sign in with a Google account. Create a new notebook and upload two or three PDFs of published papers you have. Then ask:

"Tabulate the themes these papers share and the differences in their conclusions."

The feeling of an answer drawn across several documents is likely to surprise you.

Chapter 6 summary

• Gemini Notebook answers only from what you gave it, which makes it trustworthy
• An outstanding fit for literature reviews, conference preparation and in-house teaching; audio overviews are useful too
• Your material is not used for training, but avoid confidential data and start safely with published information
