Google is upgrading its NotebookLM tool with direct support for EPUB files, a popular format for digital books. This new feature streamlines how students and book enthusiasts use the platform by allowing them to upload EPUBs straight into NotebookLM without first converting them to PDFs. This enhancement opens new ways to transform ebooks into interactive summaries, slide decks, and audio or video overviews instantly.
Until now, users had to jump through the extra step of converting EPUBs into PDFs to work with NotebookLM, which slowed down the research and note-taking process. EPUB files have become favored due to their smaller size, adaptable text layouts for different screens, and support for interactive content-advantages that PDFs lack. By embracing EPUB support, Google is removing a common pain point for its primary audience of students and researchers, making it easier to build a searchable, AI-powered knowledge base from their digital libraries.
NotebookLM has been rapidly evolving throughout 2026, integrating the latest Gemini AI models and adding Cinematic Video Overviews. The EPUB integration builds on these prior improvements, enhancing its role as a digital research assistant. Now, textbooks and reference materials saved in EPUB format can be effortlessly transformed into multiple formats for easier study and presentation.
Despite these strides, NotebookLM still lacks some important organization tools. Users currently cannot create folders to arrange their notes and notebooks neatly, risking clutter as usage scales. Additionally, simple one-click export options for sharing generated content are missing, which could further improve workflow efficiency. These gaps highlight that while Google is clearly investing heavily in NotebookLM’s capabilities, there is still room for improvement in user experience and file management.
With more students and professionals demanding smarter digital study aids, Google’s move to support EPUB signals an understanding of evolving user needs. EPUB capabilities paired with Gemini AI models position NotebookLM as a versatile tool that can process and repurpose a wide range of content formats. Expect Google to continue refining the platform, possibly introducing organizational features and export functions in upcoming updates to boost its practicality further.
