Hjarni

Hjarni is a note-taking app your AI can actually use.
Write notes in Markdown. Organize them in folders and tags. ChatGPT reads them directly through MCP, no plugins, no copy-pasting context into every conversation.

Set instructions per folder to control how ChatGPT writes, formats, and tags your notes. Share a folder with your team. Search across everything instantly.

Your AI starts every conversation from zero. Give it a memory.
