Extractous is an unstructured data extraction tool written in Rust, offering multi-language bindings. It focuses on extracting content and metadata from various file types, such as PDF, Word, HTML, etc., with excellent performance and low memory usage. Extractous achieves fast processing speed and low memory consumption through native code execution, supports multiple file formats, and integrates Apache Tika and Tesseract-OCR technology for a wide range of file handling and OCR capabilities. The open-source nature and Apache 2.0 license allow for free commercial use, making it suitable for enterprises and developers handling large volumes of document data.

The pdf-extract-api is an API that utilizes modern OCR technology and Ollama-supported models to convert any document or image into structured JSON or Markdown text. It is built using FastAPI and employs Celery for asynchronous task processing, with Redis used for caching OCR results. The API has no reliance on cloud services or external dependencies, ensuring that all processing is completed in a local development or server environment, thereby safeguarding data security. It supports high-precision conversion from PDF to Markdown, including tabular data, numerical or mathematical formulas, and can convert PDFs to JSON using Ollama-supported models. Additionally, the API supports LLM-enhanced OCR results, removing personally identifiable information (PII) from PDFs, as well as distributed queue processing and caching.

MixTeX is an innovative multimodal LaTeX recognition application independently developed by our team, capable of performing efficient CPU-based inference in local offline environments.

Thanks to its robust technical support and optimized design, MixTeX operates efficiently without the need for GPU resources, making it suitable for any Windows computer, greatly enhancing user experience.

RapidOCR is a multilingual OCR toolkit based on ONNXRuntime, OpenVINO, and PaddlePaddle. It converts PaddleOCR models into ONNX format, supporting multi-platform deployment in Python, C++, Java, and C#. It is characterized by speed, lightweight design, and intelligence, addressing memory leakage issues present in PaddleOCR.

Comic Translate is a desktop application designed to automatically translate various comic formats, including BD, Manga, Manhwa, and Fumetti, supporting multiple languages. Leveraging the powerful translation capabilities of GPT-4, it is particularly effective in translating language pairs that other translators may struggle with, such as Korean to English and Japanese to English. The application supports multiple file formats like images, PDF, Epub, cbr, and cbz, offering users a convenient way to enjoy comics in different languages.

OmniParse is a data parsing platform that converts various unstructured data into structured, actionable data, particularly suitable for Generative AI (GenAI) applications. It supports data types such as documents, tables, images, videos, audio files, and web pages. By providing clean, structured data, it prepares AI applications like RAG, fine-tuning, etc.
