Gabriel Chua, a data scientist working at Singapore’s GovTech, has launched an open-source alternative to Google’s NotebookLM. The new tool, called Open NotebookLM, replicates the main functionality of the AI-powered research assistant from Google, but does so without any costs attached. Chua managed to create this system in just a few hours using publicly available AI models.
The open-source tool converts PDFs into podcasts, allowing users to transform written documents into audio content. Unlike Google’s product, which is deeply integrated into its ecosystem, Chua’s creation is available for anyone to use or modify freely. Open NotebookLM is available on GitHub and Hugging Face.
A Simple AI Tool for PDF-to-Podcast Conversion
Open NotebookLM utilizes Meta’s Llama 3.1 language model and MeloTTS for speech synthesis, making it capable of converting PDF documents into podcasts with relative ease. It features a straightforward interface, built using Gradio and hosted on Hugging Face Spaces, which makes it accessible even to users without technical expertise.
While Google’s NotebookLM benefits from its proprietary AI technology and vast computational power, Open NotebookLM holds its own with language support for over ten languages, including Spanish, French, and German. Users can customize the tone of the AI-generated voice, choosing between a “fun” or “formal” tone, adding a unique element of flexibility.
Google’s NotebookLM and Its Advanced Capabilities
Google’s AI tool offers more features than just converting documents to audio. NotebookLM provides users with a detailed summary of uploaded documents and allows them to ask questions, generating responses with citations from the material. A standout feature is the ability to create podcasts that simulate a discussion between two speakers based on the document content.
Launched initially as Project Tailwind during Google I/O in June 2023, NotebookLM became accessible in the U.S. by December 2023. The app has since expanded globally to over 200 countries and supports 108 languages. Last month, Google expanded NotebookLM with new features like YouTube video summarization and audio file analysis.
NotebookLM’s feature set, along with its integration with Google services like Slides and web URLs, puts it ahead of most competitors in terms of versatility and ease of use. By comparison, Open NotebookLM focuses on its PDF-to-podcast feature, with the added benefit of being free and open-source. However, it lacks the integration and advanced fact-checking capabilities that Google’s version offers.
The Speed of AI Development and Its Implications
The rapid development of Open NotebookLM reflects the growing trend of creating AI tools in a short time frame, a task that previously required large teams of developers. However, quick development often raises concerns about reliability and security. While open-source tools offer great potential for customization, they may not be as rigorously tested as commercial solutions.
As smaller developers begin to replicate what once seemed like exclusive technologies from major tech companies, it suggests a shift in how AI applications are built and distributed. Open NotebookLM is a prime example of how open-source tools can disrupt markets dominated by proprietary systems. However, it also underscores the need for careful consideration regarding the security and ethical use of AI tools.
Open Source AI Competing with Big Tech
In May 2023, A Google employee wrote a memo offering a pessimistic view of Google’s ability to compete with open source AI. The author proposes that Google should not engage in direct competition with open-source AI but rather assume a leadership role within this community.
By establishing dominance within the open-source ecosystem, similar to its achievements with Chrome and Android, Google can exert considerable influence over the trajectory of AI innovation. To realize this objective, the author suggests that Google might need to disclose the weights of smaller universal language model (ULM) variants and foster collaboration with the wider open-source community.
However, Demis Hassabis, the head of Google’s DeepMind publicly responded to the memo, saying he does not agree with it. He says that Google’s researchers have a competitive spirit that will keep Google at the forefront of AI. He also mentions that the combination of Google Brain and Google DeepMind, which he was asked to lead, will likely result in more breakthroughs.
