What the publisher says

From the sourcebolt repository's README, as published. We do not edit it. Read it on GitHub

sourcebolt

Let your AI assistant use your Google NotebookLM notebooks: one small, fast program, nothing else to install.

Install in 2 minutes

Windows (open PowerShell, paste, press Enter):

irm https://raw.githubusercontent.com/candidloom-hub/sourcebolt/main/install.ps1 | iex

macOS and Linux (open Terminal, paste, press Enter):

curl -fsSL https://raw.githubusercontent.com/candidloom-hub/sourcebolt/main/install.sh | sh

The installer checks the download, installs sourcebolt for your user only, and then offers sourcebolt setup. Setup finds your AI apps, connects the ones you pick (keeping a backup of their settings), and opens a browser window so you can sign in to Google. Your password goes only to Google.

Independent project. sourcebolt is not made by, endorsed by or sponsored by Google. "NotebookLM" is a trademark of Google LLC. NotebookLM has no public API for personal accounts, so sourcebolt uses the same internal web calls the NotebookLM website makes. Read Limits and risk before you rely on it.

What it does

sourcebolt is an MCP server. MCP (Model Context Protocol) is the standard way AI apps such as Claude, Cursor, VS Code and Codex call outside tools. Once sourcebolt is connected, you can ask your assistant things like:

"List my NotebookLM notebooks."
"Add these three articles to my Thesis notebook."
"Ask the Thesis notebook what the sources say about sample size, with citations."
"Research recent work on battery recycling and import the best sources."

The assistant calls sourcebolt, sourcebolt talks to NotebookLM with your own Google session, and the answer comes back with citations from your sources.

Key numbers

Quick start

Sign in. Start Brave or Chrome with a debugging port, sign in to NotebookLM in that window, then run:

sourcebolt login --attach http://127.0.0.1:9222
