Hjarni
by hjarniofficialv1.0.0
Hjarni is an AI-native note-taking app that allows users to write and organize notes in Markdown, while enabling AI interfaces like Claude and ChatGPT to search, read, create, and organize these notes via an MCP server.
From the registry: Markdown-based note-taking with a hosted MCP server. Your notes serve you and your AI.
