NotebookLM Ultra Exporter is a browser extension for Google Chrome that adds export and batch management functions to Google NotebookLM. It enables users to export AI-generated notes, research reports, slides, mindmaps, data tables, flashcards, chat history, and sources from NotebookLM into formats including Markdown, PDF, Word, CSV, PowerPoint, and Anki-compatible files. The extension supports batch export of multiple notes and research reports, batch download of slides, creation of long images, and direct export to PowerPoint. It can export mindmaps as scalable images, structured data tables to spreadsheet-compatible formats, and flashcards to Anki or other flashcard applications. Users can save chat history for reference, sharing, or analysis. Source management features include batch download of sources in Markdown, PDF, or TXT format, bulk deletion, and filtering by content type such as All, Docs, Web, and PDF. Optional settings allow users to toggle batch capabilities and adjust export settings. Typical use involves installing the extension in Chrome, opening notebooklm.google.com, selecting a notebook, and using the export button next to a content item to choose a format. No account is required. Processing occurs locally in the browser, and the extension does not collect, track, or sell user data. The extension is open source and requires Chrome and access to Google NotebookLM. It is intended for researchers, students, and professionals who need to move NotebookLM content into document, presentation, spreadsheet, image, or flashcard workflows.
