LangChain4j-AIDeepin is an open-source, self-hostable AI application platform built on Spring Boot, LangChain4j, and LangGraph4j with Vue 3 frontends. It bundles AI chat, image generation, RAG knowledge bases (vector and knowledge-graph retrieval), a visual workflow editor, an MCP service marketplace, ASR/TTS, and short/long-term memory for building intelligent business assistants.

Use cases

• build a self-hosted ai chat assistant with a knowledge base
• create a rag chatbot over company documents
• design ai workflows with a visual editor
• connect mcp tools to an ai assistant
• add voice input and output to an ai chat app
• generate images from text prompts with multiple model providers
• give an ai assistant long-term memory of past conversations
• expose characters, knowledge bases, and workflows via a rest api

When to choose

• you want an all-in-one, self-hosted AI assistant platform with chat, RAG, and workflows
• your stack is Java/JVM and you want to build on LangChain4j
• you need both vector search and knowledge-graph (GraphRAG) retrieval
• you want MCP tool integration and a marketplace out of the box
• you need multi-provider LLM support (OpenAI, Qwen, Ollama, SiliconFlow) with streaming

When to avoid

• you need a lightweight library to embed in an existing app rather than a full platform
• your stack is Python-centric (LangChain, LlamaIndex ecosystems may fit better)
• you only need a simple chatbot UI without knowledge bases or workflows
• you require enterprise-grade scalability guarantees or commercial support
