## About

Hjarni is a knowledge base your AI can actually use.

Write notes in Markdown. Organize them in folders and tags. ChatGPT reads them directly through a built-in MCP server. No plugins. No pasting the same context into every conversation.

ChatGPT starts every conversation from zero. Connect Hjarni once and it stops asking. Ask questions across all your notes. Have ChatGPT write new notes, update old ones, and tag them the way you want.

Set instructions per folder to control how ChatGPT 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.

Built on the same open MCP standard as Claude, so your knowledge base is not locked to one assistant.

Use it as your second brain, your project memory, your research library, or your team's shared context. Notes, folders, tags. That is the product. Simple on purpose.

Free to start. No credit card required.

## How to use

1. **Add it in ChatGPT** Open Hjarni Notes in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Hjarni Notes, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.
