NotebookLM Now Supports EPUB (Ebook Upload Test)

Are you still wasting time converting your eBook library into PDFs just to get them into NotebookLM? Many of us have massive research collections trapped in .epub formats, and until now, those files were essentially unusable to NotebookLM. Watch as I put a recent backend update to the test. I pull a full copy of Alice in Wonderland directly from Project Gutenberg to show you exactly how NotebookLM handles EPUB and EPUB 3 files. The EPUB Integration Blueprint: - Verify the Source: Ensure your file is in a standard .epub or EPUB 3 format. - Add the Source: Hover over the "Add Sources" menu in NotebookLM to see the newly added EPUB icon. - The High-Speed Upload: Take advantage of EPUB's small file size for near-instant indexing. - Cross-Account Check: Confirm functionality across both Free and Pro NotebookLM tiers—I tested and verified both. Parting thoughts: - Google is notorious for changing things and removing features with no notice, so keep an eye on the "Add Sources" option for changes. - While EPUBs index much faster than PDFs, very large textbook files might still push the boundaries of the context window. - If you have hundreds of sources, you might encounter an upload failure. ✨Learn NotebookLM In A Weekend → https://maven.com/thoughts-brewing-llc/learn-notebooklm-in-a-weekend-1-cohort 🌟 Request a video: https://thoughtsbrewing.com/en-us/youtube-video-request-page?utm_source=youtube #NotebookLM #AIResearch #WorkflowHack #AIQuickTips #ThoughtsBrewing ➡️ Subscribe: https://www.youtube.com/@thoughtsbrewingllc ➡️ Follow the Blog: https://thoughtsbrewing.com/en-us/blog-subscription?utm_source=youtube 🔗 Project Gutenberg: https://www.gutenberg.org/ Timestamps 0:00 - Does NotebookLM now support EPUB files? 0:45 - Where can you find free EPUBs to test in NotebookLM? 1:15 - How do you add an EPUB file to a NotebookLM notebook? 2:20 - Why are EPUBs faster to process than PDFs? 3:10 - Does EPUB support work on free NotebookLM accounts?
