How to Use NotebookLM as Your Personal Teaching Assistant (2026 Guide)

This post is a companion to the YouTube video — watch it here for the full walkthrough.

Teaching means keeping a dozen mental tabs open at once: Are my resources current? Are students getting enough retrieval practice? Is my unit aligned with the latest syllabus? Google’s free AI tool NotebookLM can take a lot of that cognitive load off your plate — and in the video above, I show you exactly how to set it up as a teaching assistant for any unit, project, or class.

Here’s a quick-reference summary if you want the highlights before (or after) you watch.

Getting Started

NotebookLM doesn’t train Google’s AI on your uploaded documents — your files stay private, and you control who you share a notebook with. On the free plan, you get up to 50 sources per notebook, 100 notebooks total, and limited access to Studio features.

Think of each notebook as a second brain for one specific unit or purpose — for example, a Year 9 Space topic.

Adding Sources the Smart Way

NotebookLM accepts PDFs, YouTube videos, Google Docs, and most common file types. Upload your unit plan, curriculum documents, strategy resources, or student-facing materials.

A couple of tips that make a big difference:

• Google Docs sync automatically. If your unit plan is a living document, keep it in Drive — any edits you make later will flow straight into NotebookLM.
• Quality over quantity. Three well-chosen sources will outperform twenty random ones. NotebookLM’s answers are only as good as what you feed it.
• Need more material? Use the built-in Google search or the deep research feature (10 free queries/month on the free plan).

Using the Chat

The interface has three sections: Sources on the left, chat in the middle, Studio on the right.

Start by giving the chatbot a clear role, e.g.:

“You are a Year 9 Science teaching assistant. Use the uploaded sources to help me plan lessons, design assessments, create differentiated tasks, and identify potential student misconceptions. For every response, name the specific document you’re drawing from. Keep insights concise and practical.”

You can also select only the sources relevant to a specific question instead of querying everything — no need to delete anything, just untick what’s not relevant.

Some prompts worth stealing:

• “Give 3 simple questions to check for prior understanding before we begin this program with Year 9 students.”
• “I want to use the teaching strategies from this PDF in my program — identify some focus areas for me.”
• “Which concepts are most likely to confuse English language learners? Suggest scaffolding strategies for each.”

Pro tip: save your best chat responses as notes, then convert them into sources. NotebookLM can then reference its own past answers — it builds on itself over time.

The Studio Panel

This is where things get fun. From your sources, Studio can generate a quiz, study guide, audio overview, video overview, flashcards, or infographic — all curriculum-aligned because everything is grounded in your uploaded material. No hallucinations, no invented facts.

In the video, I generate a 10-question quiz live and walk through a public Chemistry notebook built entirely from free OpenStax textbooks, including its interactive audio overview, to show what’s possible once you’ve built out a notebook over time.
