# Auto-Route Web Pages to NotebookLM Notebooks
Domain Router sends a saved web page to the right Gemini Notebook (formerly NotebookLM) notebook, based on its address. It acts only when no notebook was chosen, such as with the side panel's Domain Router button or a Bulk Import CSV.
This needs Kortex Pro. See [pricing](https://www.kortex-notebooklm.com/#pricing).
## Why use Domain Router?
It is like a post office clerk. Mail for one town goes in one bag, and mail for another town goes in another bag.
- You never have to ask "which notebook was this for?"
- Work, school and home stay apart.
- It helps most when you save a lot of pages from the web.
## How do I set it up?
1. Open **Automation** and click **Create Pipeline**.
1. Name it, for example "Papers to Papers notebook". Press **Next**.
1. For the trigger, click **Domain Router**.
1. In the **URL Contains** box, type the text to look for, such as `arxiv.org`.
1. For the action, choose **Target Notebook** and pick the notebook.
1. Press **Next** and save.
## Examples
- `youtube.com` goes to _Watch Later_.
- `arxiv.org` goes to _Papers_.
- `/cs224n/` goes to _NLP Class_.
- `topic=machine-learning` goes to _ML Research_.
:::tip Good to know
- Domain Router only acts when you have not picked a notebook yourself. That happens with the side panel's **Domain Router** button, with the Bulk Import CSV option, and with **Create New Notebook** from the NotebookLM button on an AI site.
- Older versions of Kortex had a separate Domain Router screen. Today it is simply a pipeline built in the same wizard as every other rule. If you had a Domain Router rule before, Kortex moved it into a pipeline once, named after the old type.
