Arrowhead is a powerful tool designed for managing and searching your Obsidian vault efficiently. As a cross-platform command-line interface (CLI) and daemon, it continuously indexes your markdown files, allowing for fast full-text search, semantic analysis, and enhanced graph analytics. It features a background daemon that monitors file changes, ensuring the index is always up-to-date while respecting your Obsidian settings and configurations. Users can perform CRUD operations on notes and utilize advanced searching capabilities, including hybrid search modes that combine both full-text and semantic queries.

The program integrates seamlessly with AI agents, enabling them to access your organized knowledge base effortlessly. It supports various transport modes, including standard input/output (stdio) and HTTP, allowing for flexible client interactions. Arrowhead also provides extensive customization options through workspace configuration files, ensuring compatibility with diverse markdown setups. With its robust architecture built in Rust, Arrowhead promises efficient performance and a user-friendly experience for anyone looking to enhance their note-taking and knowledge management workflows.
