dotnet-data-ingestion-local-rag offers a simple way to search and retrieve information from your own .md documents on your Windows PC. It keeps everything local, so your documents never leave your machine. The software uses a combination of SQLite for data storage, Ollama for AI processing, and MarkItDown to manage your markdown files. It is built on Microsoft's .NET 10 platform, which ensures stable and efficient performance.

This app is designed for users who want privacy and quick semantic search inside their markdown files. There's no need for internet access once the app is installed.
