ocrAI 🤖

ocrAI is a unified web application that combines Optical Character Recognition (OCR) and Artificial Intelligence (AI) to process and translate documents, offering a simple, intuitive interface with real-time feedback (even with emojis!).

Key Features

• File Management 📤

  • Upload PDF or image files using drag & drop or manual selection.
  • Files are saved with unique names to avoid overwrites.
  • The "Delete All Files" button removes all files from both the "uploads" and "outputs" folders.

• OCR Processing Modes 🔍

  • OCR (Tesseract Only):
    Extracts text with Tesseract and embeds it into the PDF using OCRmyPDF. The TXT file contains the raw OCR output.
  • OCR + AI (Tesseract + AI):
    Uses Tesseract to extract text and then sends it to an AI model (e.g., Gemini) to correct and format the content. The TXT file shows the corrected and structured text, while the PDF retains the original Tesseract output.
  • AI (Full AI OCR):
    Leverages the AI model's OCR capabilities to process the document page by page. The TXT file includes clear page markers, making it easy to compare with the original document, and the original PDF is preserved.
  • All modes display real-time progress updates with emojis (e.g., 📤, ✅, 🤖, 🎉) and run in the background.

• Translation 🌐

  • Translates PDF or TXT documents page by page.
  • You can upload a new file or select one from the list of processed files.
  • Progress updates are displayed, and a TXT file with the final translation (including page markers) is generated.

• Configuration ⚙️

  • Manage and add new AI models (including the ability to add or delete Gemini models) and languages.
  • Update or add custom prompts for OCR, correction, and translation functions.
  • Download or upload the complete configuration (which includes prompts and models).

How to Use the Application

1. Upload and Process Files:

   • Go to the OCR tab.
