PDF Annotation and Highlight Extractor

This tool extracts annotations (like comments and highlights) from a PDF file and intelligently organizes them under the document's existing headings. This makes it easy to get a structured summary of your notes.

✨ Features

• Automatic Heading Detection: Finds headings by looking for a Table of Contents or by analyzing font styles (size and boldness).
• Comprehensive Annotation Extraction: Pulls out highlights, underlines, comments, and other common annotation types.
• Contextual Organization: Maps every annotation to the correct heading, so you know which part of the document your notes refer to.
• CSV Export: Saves all the extracted data into a clean, easy-to-use CSV file.
