# Libragen

> Use this tool when you need to create private, local knowledge libraries from files or Git repositories, and require offline access to hybrid search capabilities. Libragen solves problems related to information retrieval and knowledge management by providing a self-contained, shareable library with vector and BM25 search functionality. It takes in files or Git repositories as input and outputs a SQLite file with embeddings, suitable for use cases where cloud services or API keys are not desirable.
