I wanted to share a simple browser-based tool called NotebookLM Remover.

NotebookLM Remover helps clean NotebookLM exports and remove unwanted watermarks from videos, PDFs, PPTX files, images, and research materials.

Official website:
https://notebooklmremover.org/

It can be useful for students, researchers, educators, content creators, and teams who use NotebookLM to prepare cleaner study notes, presentations, tutorials, documentation, or research materials.

The workflow is simple:

1. Export the original material from NotebookLM.
2. Review the exported video, PDF, PPTX file, image, or research document.
3. Remove unwanted watermarks or extra export elements.
4. Save a cleaner version for sharing, archiving, presentations, or documentation.

NotebookLM Remover works directly in the browser and does not require installing extra software.
