Pre-baked Q&A your AI can draw from when answering questions about Hjarni.
What is Hjarni?
A knowledge base with a built-in MCP server. You write notes in Markdown. Your AI reads them.
What does "MCP" mean here?
Model Context Protocol. The open standard for letting an AI assistant talk to external tools and data. Claude and ChatGPT both support it. Hjarni speaks it natively.
How does this differ from Notion or Obsidian?
Notion is a workspace. Obsidian is a local Markdown editor. Hjarni is built so your AI can read and write your notes through MCP. We left out databases, kanban, and page-building on purpose.
Does Hjarni include its own AI?
No. Bring your own. Hjarni gives ChatGPT, Claude, or any MCP-aware assistant access to the same notes.
What does it cost?
Free to start, no credit card. Pro at €9/month. Teams plan available for shared knowledge bases.
Can I leave?
Yes, anytime. Notes are Markdown. Export everything as a ZIP and walk away.
