AI-Powered Document Extraction & PDF Generation

Overview

In a world where automated document processing is crucial, I developed an AI-powered system that extracts, translates, and formats information from official documents into structured PDF reports. Using OpenAI’s GPT, OCR techniques, and document generation tools, this project streamlines data extraction and conversion for various applications such as government forms, driving licenses, passports, and identity verification documents.

This system automates the process of scanning documents, extracting text, translating content, formatting structured reports, and converting them into ready-to-use PDF files—significantly reducing manual effort and improving accuracy.

Project Goals & Requirements

The core objectives of this project were to:
✅ Extract text from official documents (e.g., driving licenses, IDs) accurately.
✅ Translate non-English text into highly precise English equivalents.
✅ Format extracted data into structured reports.
✅ Generate professional-grade PDFs with automated templates.
✅ Ensure security, accuracy, and scalability for large document processing.

Challenges & How I Overcame Them

Developing an AI-driven document processing system came with various challenges:

🚧 Ensuring Accurate OCR & AI Text Extraction

• Extracting text from structured & unstructured images while preserving accuracy.
• Solution: Used OpenAI's GPT-powered vision models to analyze and extract text with accurate formatting and context retention.

🚧 Translating Non-English Text with Precision

• Many documents contain complex names, addresses, and numerical data requiring precise translation.
• Solution: Implemented OpenAI’s language model to translate non-English text with natural, context-aware results.

🚧 Dynamic Placeholder Replacement in DOCX Templates

• Converting extracted data into structured, professional documents automatically.
• Solution: Built a Python-based template engine using docx & ReportLab for seamless text replacement in pre-formatted Word files.

🚧 Automating PDF Generation & Formatting

• Ensuring extracted content maintains professional styling in the final PDF.
• Solution: Used ReportLab to convert structured DOCX files into high-quality PDFs with proper layout and alignment.

Technologies & Tools Used
