Coaching institutes often sit on a goldmine — years of manually curated question papers in PDF format or physical printouts. Digitizing this archive manually would take months. PrepLab's AI PDF extraction pipeline does it in hours.
This guide walks through the exact process of converting your PDF question papers to a live digital test.
How PrepLab PDF Extraction Works
Step 1: Upload the PDF
Drag and drop your PDF into the PrepLab Document Upload portal. Supports scanned PDFs, native PDFs, and image-based PDFs.
Step 2: AI Processing
The AI pipeline processes each page: identifying question starts, extracting options (A-D), detecting math/chemistry content, and rendering LaTeX.
Step 3: Review the Extracted Questions
A structured preview shows each extracted question. You can edit any item, mark the correct answer, or flag questions for review.
Step 4: Build the Test
Select all or some extracted questions and publish as a new test directly, or add them to your question bank.
