📄 OCR Reader, 🔍 Analyzer, and 💬 Chat Assistant using 🔎 Zerox, 🧠 GPT-4o, powered by 🚀 AI/ML API

What I Built

I built an OCR Document Reader that allows users to upload and extract text from various document types such as PDFs, Word, and documents. The app utilizes the Zerox library for Optical Character Recognition (OCR) and integrates the AI/ML API's GPT-4o model for advanced text analysis. With features like support for multiple document formats, text analysis, and an interactive interface built with Gradio 5.0, this app simplifies the process of extracting and analyzing text from complex documents.

Limitations

• Processing Time: Enabling the maintain_format option can slow down processing due to sequential requests needed to preserve formatting.
• API Constraints: The app's capabilities depend on the limitations of the AI/ML API plan, such as request quotas and document size restrictions.
• System Dependencies: Requires installation of system packages like poppler-utils, which may not be straightforward on all platforms.

Demo

Here are some key features of the app:

• Upload Documents:
  
  Users can upload PDFs, Word documents, or images for OCR processing.

• Extracted Text Display:
  
  The extracted text is displayed within the app, with options to copy or download it.

• Maintain Formatting:
  
  Optionally preserve the original document's formatting in the extracted text.

Tech Stack

• Python: Core programming language.
• Gradio 5.0: For building the user-friendly interface.
• Zerox: Library used for OCR processing.
• AI/ML API: Provides the GPT-4o model for text analysis.
• LiteLLM: Used under the hood for model interactions.

More Details

• Zerox Library: Transforms uploaded documents into images and performs OCR to extract text.
• AI/ML API's GPT-4o: Analyzes the extracted text, enabling advanced features like summarization or content analysis.
• Gradio Interface: Offers an intuitive web-based UI for users to interact with the app seamlessly.

Future Improvements

1. Batch Processing: Enable users to upload and process multiple documents at once.
2. Advanced Formatting Preservation: Improve the ability to retain complex layouts, tables, and graphics.
3. User Accounts: Implement authentication to allow users to save and manage their processed documents.
4. Cloud Integration: Add options to upload documents from and save results to cloud storage services.
