How It Works

1. Export your NotebookLM presentation as PDF

Technical Details

The tool uses a texture cloning + edge feathering algorithm:

1. Locates the watermark region (bottom-right corner)
2. Copies texture from directly above the watermark area
3. Applies 12px alpha gradient blending on edges for seamless transition

This approach preserves background gradients and textures better than traditional inpainting methods.
