It exports Markdown, HTML, DocTags and lossless JSON, runs locally for sensitive or air-gapped data, and integrates with LangChain, LlamaIndex, CrewAI and Haystack. It also ships an MCP server and an API server. The code is MIT-licensed; models carry their own licenses. Started at IBM Research Zurich and hosted by the LF AI & Data Foundation.
