AI & Automation

An open-source alternative to Google NotebookLM

Open Notebook is the one project in our catalog listed as a replacement for Google NotebookLM. It is ai assistants software with 41K GitHub stars. Below is how it measures against the questions people usually ask first.

Open Notebook

AI assistants

Turn your research files into searchable notes, chats and podcasts.

Open Notebook gives researchers and teams a NotebookLM-style workspace that runs on their own server. You decide which AI provider sees your material, or keep everything local with models run through Ollama. Instead of a monthly subscription, you pay only for the AI usage you choose.

  • Organise PDFs, web pages, YouTube videos, audio and Office files into separate notebooks.
  • Chat with your research and get answers that cite the sources and notes they used.
  • Generate podcast episodes with one to four speakers from your sources and notes.

What people use it for

Build a private research library for a project

Create a notebook and open the Add Source wizard to add URLs, upload files or paste text. Tick Enable embedding for search so vector search and Ask can find the content. Audio and video files are transcribed with the Speech-to-Text model you set under Manage, then Models.

Summarise every new document the same way

Go to Manage, then Transformations, and create a saved prompt such as a key-points summary, or use built-in ones like Dense Summary and Key Insights. Tick it in the Process step when adding a source, and the result is saved as an insight on that source. Try new prompts first in the Playground tab.

Turn research into an audio briefing

Set up a speaker profile with a text-to-speech model and one to four speakers, then an episode profile with outline and transcript models, a number of segments and a briefing. Pick the sources and notes to include and start an episode. Generation runs in the background worker, so you can close the browser while it works.
