CleanMark
Remove Google AI watermarks (NotebookLM & Gemini) from PDFs and images instantly
About
Google's AI tools like NotebookLM and Gemini are incredible for generating content, but they automatically add watermarks to all outputs. NotebookLM adds a "NotebookLM" text watermark to every PDF page, while Gemini places watermarks on AI-generated images. These watermarks can look unprofessional when you need to share documents with clients, publish research papers, or use the content in presentations. **Our Solution:** Gemini Watermark Remover intelligently removes watermarks from both NotebookLM PDFs and Gemini-generated images while preserving the original quality. **Key Features:** 🔒 **Privacy First:** - Files are processed securely and deleted immediately after - No permanent storage of your documents - Secure encryption during upload and processing
