Google has been stacking updates onto NotebookLM throughout the school year, and the latest round directly affects how much teachers and students can do with the tool. The April 2026 update expanded usage limits for Education Plus and Teaching and Learning add-on users across sources, chat queries, flashcards, and multimedia outputs - all at no additional cost.
NotebookLM is included in all Google Workspace for Education editions free of charge and is available to users of all ages. That baseline hasn't changed. What changed is how much headroom qualifying users now have to work with it across a full semester.
NotebookLM Education Plus: April 2026 Update
Starting April 6, 2026, Google began rolling out expanded NotebookLM capabilities for customers with Google Workspace for Education Plus or a Teaching and Learning add-on license, at no additional cost. The rollout takes up to 15 days to reach all accounts.
The clearest signal that your account has been upgraded: a Plus badge will appear next to your profile picture, indicating access to higher usage thresholds.
The standard free tier has real ceilings that the April update pushes past. Here's what the base plan gives you:
-
100 notebooks, up to 50 sources each
-
50 chat queries per day
-
3 audio generations per day
What's Included in the Expanded Limits
Users with Education Plus or a Teaching and Learning add-on license now benefit from four key upgrades:
Google hasn't published the exact numbers publicly yet. To check your current limits, visit the NotebookLM Help Center or look for the Plus badge in your account.
It's also worth clarifying who qualifies. To access higher usage limits with a school account, your organization needs a qualifying Google Workspace for Education edition and your administrator must have enabled access to NotebookLM for your account. If you're a student and don't see the Plus badge yet, the best move is to contact your IT admin.

Visualize Your Ideas with Diagrimo
NotebookLM is excellent at turning your sources into summaries, audio, and study tools. What it doesn't do is help you build visual diagrams to map out concepts, plan lessons, or communicate ideas to others.
That's where Diagrimo comes in. It's a text-to-visual tool that turns written descriptions into clean, polished visuals without any design experience required. You type what you want to show, and Diagrimo handles the layout and styling automatically.
Some ways educators and students are using it:
-
Creating visual summaries of lesson topics for class presentations
-
Mapping out essay arguments or project structures before writing
-
Building comparison visuals for study guides
-
Turning research notes into shareable infographic-style layouts
-
Planning curriculum timelines and unit outlines visually
If you're already using NotebookLM to generate content, Diagrimo is a natural next step for turning that content into something visually clear and presentation-ready.
How to Set Up NotebookLM for Your Classroom
Getting started with NotebookLM for teachers is straightforward, whether you're setting it up as an admin or using it directly in Google Classroom.
For Admins
NotebookLM is enabled by default as a Core Workspace Service for all Workspace for Education institutions. If your school is already on Google Workspace for Education, your users likely have access already. You can disable it at the domain, OU, or group level from the Admin console if needed.
For Teachers
Educators can create a NotebookLM notebook directly from Google Classroom. From the Classwork tab, select NotebookLM and pull in resources already assigned to the class, including slide decks, reading passages, and study guides. From there, you can generate Audio Overviews, mind maps, interactive study guides, and more, then assign them directly to students.
A practical starting point: pick one unit with a heavy reading load, upload the materials into a notebook, and generate a flashcard set and an Audio Overview. Share both with students as optional review resources and see what the uptake looks like.
For Students
The simplest organizational approach is one notebook per course. Upload all materials for that course into a single notebook, then ask questions grounded in those specific sources. Before class, upload the pre-reading and ask for a summary of key concepts. After class, add your notes and generate a quiz to check your understanding.
