NotebookLM Tags: Organize and Filter Your Notebooks
Add color-coded tags to your NotebookLM notebooks and quickly find the projects you need. NotebookPlus helps you categorize, search, filter, and manage your NotebookLM notebook library.
Organize your NotebookLM library without changing your existing notebooks.
Why Use Tags for NotebookLM?
As your NotebookLM library grows, finding the right notebook can become difficult.
You may have notebooks for:
- Research projects
- University courses
- Client work
- Writing projects
- Personal projects
- Business research
- Different topics and subjects
Instead of relying only on notebook names, tags give you another way to categorize your notebooks.
For example:
- Research
- Work
- Study
- Writing
- Clients
- AI
You can then use these categories to quickly filter your notebook library.
What Are NotebookLM Tags?
NotebookLM can organize individual sources with labels and categories. However, organizing an entire notebook library is a different problem.
NotebookPlus adds color-coded tags for your notebooks.
This lets you organize your NotebookLM library at the notebook level.
Think of it as two different layers:
Source labels → organize sources inside a notebook
Gemini Notebook / NotebookLM can label and categorize individual sources inside a notebook.
NotebookPlus Tags → organize notebooks across your library
NotebookPlus tags help you categorize, filter, and search entire notebooks in your library.
This makes tags especially useful when you have many separate NotebookLM notebooks for different projects or topics.

Tags vs Folders vs Collections
NotebookLM organization becomes much easier when you understand what each tool is designed to organize.
| Feature | Organizes | Best For |
|---|---|---|
| Collections | Notebooks | Grouping notebooks into larger projects |
| NotebookPlus Tags | Notebooks | Flexible categories and filtering |
| NotebookPlus Source Folders | Sources | Organizing sources inside a notebook |
| NotebookLM Source Labels | Sources | Categorizing individual sources |
Collections
Use Collections when you want to group entire notebooks together.
For example:
Work → Marketing Notebook, Product Research Notebook, Competitor Notebook
NotebookPlus Tags
Use Tags when you want flexible categories that can overlap. This makes tags useful when a notebook belongs to multiple categories at the same time.
For example, one notebook could have:
- Research
- Important
- Client A
Source Folders
Use source folders when the problem is inside a specific notebook and you need to organize the individual sources.
For example:
Research Notebook → Papers, Websites, Interviews, Videos
Tags and Collections Work Together
Tags and Collections don't have to replace each other. They can be used together.
For example:
Collection: Client Projects
Inside it:
- Client A Research
- Client B Research
- Client C Research
Then use tags such as:
- Research
- Active
- Important
This gives you both a high-level organization system and a flexible filtering system. Collections can help you group related notebooks into broader categories such as Work, Research, Study, or Personal. See how to organize NotebookLM.
Manage Your Tags
Your NotebookPlus Tags manager is designed for users with larger notebook libraries.
Merge Tags
If you have created duplicate or overlapping tags, merge them into one category.
- Research

can be consolidated into:

How Many Tags Should You Create?
There is no need to create a tag for every notebook.
A simple tagging system is usually easier to maintain.
Start with a few broad categories:
- Work
- Research
- Study
- Personal
Then add more specific tags only when they become useful.
For example:
Research → Academic, Market Research, Competitors
This keeps your notebook library organized without creating unnecessary complexity.
