What Is the NotebookLM Watermark?
Google NotebookLM is an AI-powered research tool that generates slide decks, audio overviews, and study guides from your source materials. According to Google's NotebookLM documentation, all exported slide decks and video overviews include a "Created with NotebookLM" watermark by default. This watermark appears as a footer on every slide page, identifying the content as AI-generated output. While the watermark serves as attribution, it can be problematic for professional presentations, client deliverables, and internal documentation where third-party branding is undesirable. Deck Cleaner was built specifically to solve this problem — removing the NotebookLM watermark layer while preserving 100% of your original slide content.
