About RAGFlow
RAGFlow is an open source retrieval augmented generation engine. It focuses on parsing documents carefully before an AI system searches them.
What it does
RAGFlow ingests files such as PDFs, images and spreadsheets and turns them into structured, searchable data. It combines vector search, full text search and re-ranking to find the most relevant passages. The platform also includes a visual builder for agents that use retrieval, tools and MCP servers in one workflow.
