SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill splits multi-subject science PDFs (physics, chemistry, biology, earth science) into per-subject documents and ensures accurate page boundary handling without relying on misleading cover or footer page numbers.

Core Features & Use Cases

Human-in-the-loop boundary verification: Gemini classifies all pages and a reviewer confirms and fixes boundaries before final split.
Per-subject split output: Generates separate PDFs for each subject with optional answer sheets where applicable.
Review pack and decision guide: Provides a review workflow and guidance to correct misclassifications and edge cases.
Use case: Ideal for university entrance exam bundles that combine science subjects and social studies, where consistent page structuring is inconsistent.

Quick Start

Run the pdf-splitter on your multi-subject science PDF and verify the page boundaries before finalizing the splits.

FAQPage Schema

How do I split a multi-subject science PDF into separate documents by subject?▼

Splitting multi-subject science PDFs involves classifying each page by subject (physics, chemistry, biology, earth science) and identifying correct boundaries to generate separate per-subject PDFs. This process handles mixed bundles and ignores misleading cover page numbers.

What is the best way to handle inconsistent page structuring when splitting university entrance exam bundles?▼

Handling inconsistent exam bundles requires per-page classification to correctly identify subject boundaries, bypassing misleading cover or footer page numbers. It accommodates variable placement of answer sheets and mixed subject bundles for accurate partitioning.

Can I manually verify PDF page boundaries before finalizing a subject-specific split?▼

Yes, a human-in-the-loop review workflow allows you to verify and correct page boundaries before finalizing the split. A review pack and decision guide are provided to help correct misclassifications and edge cases.

How does automated per-page classification work for mixed science PDFs?▼

Automated per-page classification uses Gemini-based AI to analyze and categorize each page of a mixed science PDF by subject. This classification handles blank pages and cover pages before outputting per-subject PDFs and a review bundle.

Does the PDF splitting process handle blank pages and variable answer sheet placement?▼

Yes, the PDF splitting process handles blank pages, cover pages, and the variable placement of answer sheets within the document. It ensures these elements do not disrupt the accurate identification of subject boundaries.
