Hjarni notes

Hjarni is a knowledge base your AI can actually use. Write notes in Markdown. Organize them in folders and tags. Claude reads them directly through a built-in MCP server. No plugins. No pasting the same context into every conversation. Claude starts every conversation from zero. Connect Hjarni once and it stops asking. Ask questions across all your notes. Have Claude write new notes, update old ones, and tag them the way you want. Set instructions per folder to control how Claude writes, formats, and tags. Share a folder with your team so everyone's AI works from the same knowledge base. Search across everything in one call.
