PDF Merge

😫 The Pain Point

You have Chapter 1, Chapter 2, and Appendix as separate PDFs. You need to join them into one final report. Free online tools limit file size or pose security risks for confidential data.

🚀 Agentic Solution

A Local PDF Binder that stitches files together securely on your computer.

Key Features:

• Custom Order: Drag and drop to arrange chapters in sequence.
• Bookmarks: Automatically adds a bookmark for each merged file.
• Password Protected: Can handle encrypted input PDFs.

⚔️ Phase 1: Commander (Quick Fix)

For a quick merge.

Prompt:

“I have a folder documents with PDF files. Write a Python script using pypdf to:

1. Sort: Merge PDFs in alphabetical order by filename.
2. Bookmarks: Add a bookmark at the start of each merged document.
3. Output: Save as Merged_Document.pdf.

Print progress (e.g., ‘Adding 1/5: chapter1.pdf’). Handle password-protected or corrupt PDFs (skip with warning).”

Result: One combined professional document.
