SmartRAG is a modular Python library designed for retrieval-augmented generation (RAG) workflows with large language models. It combines document ingestion, vector indexing, and state-of-the-art LLM APIs to deliver accurate, context-rich responses. Users can import PDFs, text files, or web pages, index them using popular vector stores like FAISS or Chroma, and define custom prompt templates. SmartRAG orchestrates the retrieval, prompt assembly, and LLM inference, returning coherent answers grounded in source documents. By abstracting the complexity of RAG pipelines, it accelerates development of knowledge base Q&A systems, chatbots, and research assistants. Developers can extend connectors, swap LLM providers, and fine-tune retrieval strategies to fit specific knowledge domains.

A2A4J is a lightweight Java framework designed for building autonomous AI agents. It offers abstractions for agents, tools, memories, and planners, supporting asynchronous execution of tasks and seamless integration with OpenAI and other LLM APIs. Its modular design lets you define custom tools and memory stores, orchestrate multi-step workflows, and manage decision loops. With built-in error handling, logging, and extensibility, A2A4J accelerates the development of intelligent Java applications and microservices.
