NotebookLM to Editable PPTX Conversion

Overview

NotebookLM currently generates PowerPoint (.pptx) presentations where every slide is a flattened, uneditable image. When you need to convert a NotebookLM export into an editable .pptx file, leverage this skill.

This workflow uses a native macOS Swift script (Vision framework) for highly accurate OCR on the images, followed by programmatic reconstruction of the presentation using python-pptx.

Prerequisites Ensure

1. python3 and pip are installed.
2. The python module python-pptx is installed:

   pip3 install python-pptx
   

3. A macOS environment (the Swift OCR script relies on Apple's Vision framework).

Workflow

Follow these steps precisely:

1. Extract Images from the NotebookLM PPTX

Use the extract_images.py script provided in this skill's scripts/ folder to pull the PNG images out of the uneditable presentation.

# Locate the script first
export SKILL_DIR=$(dirname $(find ~ -name "extract_images.py" | grep  |  -n 1))


 -p /tmp/pptx_images
python3   /tmp/pptx_images
