KateChat is a universal chat bot platform similar to chat.openai.com. The platform supports multiple LLM providers, MCP servers (with OAuth), RAG with semantic search for different DB (sqlite, PostgreSQL, MS SQL).

docling.rs converts documents — PDF, Office, HTML, scans, audio — into Markdown, docling JSON and the other shapes an LLM or a RAG pipeline can read. It is a Rust port of IBM's docling: the same output, byte-for-byte, from one static binary. No Python, no PyTorch. Pulling text out of a PDF is easy. Keeping its structure — headings in order, tables as tables, scanned pages read — takes layout analysis, table recognition and OCR. docling has the models for that, and a Python stack to match. docling.rs runs the same models from a single binary: PDF 4.3× faster than Python docling at under half the RAM, Office and HTML 20–60× faster, and tables that survive — cell recall 0.94 where MarkItDown gets 0.31 (numbers, method).
