What it does
Hjarni is an AI-native note-taking app. Write notes in Markdown, organize them in folders with custom AI instructions per folder, and let Claude or ChatGPT search, read, create, and organize your notes via MCP.
Your notes serve two readers: you and your AI. Hjarni stores the knowledge. ChatGPT and Claude are the interfaces.
