Add to NotebookLM, developed by WhoSowSee, is a Firefox extension that connects the browser to Google NotebookLM to speed web research. The extension captures web pages and video content and transfers them into notebooks without manual URL copying. It supports bulk imports, PDF snapshots, and multilingual UI while offering context-menu access and account switching. The tool targets students, researchers, and writers who regularly collect online sources for NotebookLM-based research workflows.

How the extension changes the research workflow

The extension removes repetitive tab-and-copy work by sending captured content directly into NotebookLM, a capability noted as replacing manual multi-step copying of URLs and tab switching. That change shortens the path from discovery to archival, so users who gather many sources can move items into a notebook while they browse rather than switching back and forth between services.

How much control it gives over imported material

Imports are configurable across formats and groupings; the tool accepts single pages, saves PDF snapshots for archival, and accepts lists for bulk import. It also lets users create new notebooks from the extension interface, which helps establish collection structure at the point of capture rather than after aggregation.

Is daily setup and use accessible to nontechnical users?

Daily operation is browser-native and menu-driven. Context-menu integration provides right-click access, and the extension exposes account switching for multiple Google profiles. Those interface choices keep common tasks within the browser UI and reduce the need for extra tooling or background configuration.

Does it support video-heavy research and cross-account workflows?

Video and account scenarios receive explicit support; the extension handles YouTube playlists, channels, and comments and includes built-in multi-account handling so captured items go to the correct NotebookLM profile. Its implementation for Firefox and compatibility with Manifest V3 make it a native choice for users who do not use Chromium-based browsers.

A focused choice for NotebookLM-centered researchers with a browser preference

Add to NotebookLM is a practical option for researchers who rely on NotebookLM and want fewer manual steps when collecting online sources. The extension’s usefulness depends on continued compatibility with NotebookLM and Firefox APIs, so it suits users already committed to that research workflow rather than those seeking a browser-agnostic clipper. It serves anyone aiming to centralize web and video research into a single NotebookLM workspace.
