What it solves

NotebookLM generates PDFs that are often difficult to edit or repurpose. This tool converts those static PDF files into editable PowerPoint (PPTX) presentations, separating the background images from the text so you can modify the content directly.

How it works

The macOS native application uses on-device technology to process files without needing an internet connection or API keys. It utilizes Apple's built-in Vision framework for text recognition (OCR), uses the LaMa model to reconstruct backgrounds after removing original text, and employs MobileSAM for extracting icons and illustrations as movable objects. Everything runs locally on Apple Silicon hardware.

Who it’s for

This tool is designed for users of NotebookLM who need to convert their generated study guides or summaries into professional, editable presentation slides on macOS.

Highlights

• Offline processing: Runs entirely on your Mac with no data uploads or API keys required.
• Editable output: Converts static PDF text into movable, editable text boxes.
• Background restoration: Automatically removes text strokes and rebuilds the underlying background textures.
• Object extraction: Can isolate icons and illustrations as independent, movable elements.
• Native performance: Optimized for Apple Silicon with GPU acceleration for image processing.
