About

LangExtract Web provides a containerized interface to Google's LangExtract library for extracting structured information from text using large language models. It offers three access methods: a modern web UI with dark mode support, a REST API with Swagger documentation, and an MCP server for AI assistant integration. The tool supports precise source grounding where extractions map back to exact text positions, few-shot learning, long document optimization through chunking, and multiple LLM providers including Gemini, OpenAI, Claude, and Ollama via LiteLLM.
