Your .NET RAG stack hides a Python sidecar. I built the engine that removes it.

Short summary

DocNest .NET eliminates the Python sidecar from RAG systems by providing a native C# implementation that preserves document structure during chunking, directly improving retrieval accuracy over naive splitting. The open .udf format enables language-agnostic document interchange—ingest PDFs in Python batch jobs, query the portable artifact in C# applications with zero Python runtime. Local ONNX embeddings and optional LLM support are available now on NuGet.

• •Removes Python runtime dependency from .NET RAG applications
• •Preserves document structure (tables, sections) during chunking for better retrieval
• •Cross-language .udf format supports Python ingestion + C# querying
