What is Zerox?

Zerox is an open-source, localized, high-precision OCR tool based on the GPT-4o-mini model, achieving zero-shot recognition without prior training. Zerox supports various file formats including PDF, DOCX, and images, and excels at handling scanned documents and documents with complex layouts, such as those containing tables and charts. Zerox's workflow involves converting the document into an image, performing OCR recognition, and finally outputting a Markdown format document for easy editing and use. Zerox provides an API interface, allowing developers to easily integrate it into their applications for automated document processing. It is widely used in enterprise document management, academic research, legal and financial fields, and education, significantly improving the efficiency and accuracy of document information extraction.

Zerox's main functions

  • Zero-sample OCR recognitionIt eliminates the need for users to provide a large number of samples for training, enabling high-precision text extraction directly from various types of documents, saving time and effort in training models.
  • Multi-format file supportIt is compatible with various common file formats such as PDF, DOCX, and images, and has excellent processing effects on scanned documents.
  • Complex layout processingIt accurately identifies and processes files with complex layouts such as tables and charts, extracts complete document information, and provides users with more comprehensive and accurate document content.
  • Markdown format outputConverting the recognition results to Markdown format makes it easier for users to edit and organize them, while maintaining the visual and structural integrity of the document.
  • API interface providedIt has an API interface, which makes it easy for developers to integrate it into their own applications to achieve automated and batch document processing functions, improve work efficiency, and expand the application scope and flexibility of the tool.

Zerox's technical principles

  • File conversionThis function converts user-submitted PDF, DOCX, and other format files into a series of images. Converting the files to image formats is a necessary step for OCR recognition, allowing the model to accurately extract the text content.
  • GPT-4o-mini model recognitionThis method utilizes the GPT-4o-mini model for OCR recognition of converted images. Based on deep learning technology, the model analyzes and recognizes text within images, understanding complex layouts and formats to accurately extract text content.
  • Result Conversion and SummaryThe process involves converting the OCR recognition results of each image into Markdown format, and then summarizing the Markdown results from all pages into a single, complete Markdown document. This process includes format conversion and requires the integration and optimization of the recognition results to ensure that the output document is complete, clearly structured, and easy for users to view, edit, and use.
