Yao is an LLM agent framework and low-code web app builder designed for orchestrating autonomous AI agents. It provides a platform to design, deploy, and coordinate agents with specialized personas that can plan tasks, utilize external tools, and execute multi-stage pipelines. The project distinguishes itself through a Model Context Protocol server for connecting assistants to external binaries and HTTP services, and a gRPC remote execution engine that allows agents to manage remote servers and devices. It includes a model-agnostic provider bridge that supports dynamic switching between vario

PaddleX is a PaddlePaddle-based framework for building, deploying, and fine-tuning AI model pipelines, with pre-built support for computer vision, OCR, document analysis, and time series tasks. It offers a toolkit of ready-to-use pipelines for image classification, object detection, segmentation, and pose estimation, alongside an end-to-end OCR document analysis pipeline that extracts text, tables, formulas, and layout information. The platform also includes a dedicated time series forecasting pipeline for analyzing historical data to detect anomalies, classify patterns, and predict future val

Sparrow 是一个 LLM 文档提取平台和基于视觉的推理引擎，旨在将图像和 PDF 转换为经过验证的结构化数据。它作为代理工作流编排器，将分类、提取和验证任务串联成多步流水线。 该系统的特色在于其后端无关的推理层，可管理本地 GPU、Apple Silicon 和云服务商上的模型。它利用基于坐标的视觉定位将提取的文本映射到精确的边界框坐标，并使用基于提示的模型引导来引导注意力并规范化数据格式。 该平台涵盖了文档智能工作流，包括用于保持结构完整性的专业图像表格处理，以及用于验证提取字段正确性的模式驱动验证。它还提供了一个用于监控 API 性能、使用分析和系统健康状况的文档分析仪表板。 架构包含一个基于插件的扩展系统，用于集成索引和编排中使用的第三方库。

sChandra is a document processing platform that converts images, PDFs, Word documents, spreadsheets, and other formats into structured output such as HTML, Markdown, or JSON while preserving layout. It can also extract specific data fields from invoices, contracts, or reports using user-defined JSON schemas, with citations back to source locations. The service supports form filling in PDF and image documents, document generation from Markdown, and extraction of tracked changes from Word files. The platform distinguishes itself with pipeline-based processing chains that combine multiple proces

Chonkie 是一个专为检索增强生成 (RAG) 流水线设计的文本分块库。它充当语义文本分割器和 RAG 数据摄取流水线，将原始文本转换为嵌入片段，以便存储在向量数据库中。 该项目通过专门的分割策略脱颖而出，包括用于保留源代码逻辑边界的基于 AST 的代码分割器，以及使用嵌入模型根据语义确定边界的语义文本分割器。它还提供了一个向量数据库摄取器，用于自动化生成嵌入并将其导出到各种存储中。 该库涵盖了广泛的功能，包括通过 OCR 和 Markdown 提取进行文档解析，多种分割方法（如基于 Token 计数和分层分割），以及通过可重用流水线进行工作流编排。它支持多种向量存储集成，包括 Qdrant、Milvus、Weaviate 和 Elasticsearch，以及将数据导出为 JSON 和 Hugging Face 数据集。 用户可以通过命令行界面执行这些操作，或将系统部署为容器化的 API 服务。

This project is an AI-powered screenshot manager and visual assistant designed for capturing screen content and processing it through large language models. It functions as an OCR translation application and screen annotation tool, allowing users to extract text from images and perform intelligent analysis of visual data. The software differentiates itself through an AI-driven OCR pipeline and the ability to convert screenshots into structured Markdown or HTML via layout-aware document transformation.
