What problem does Hjarni solve?

Your AI forgets everything between sessions. You spend half of every conversation re-explaining your codebase, your company, your style. Hjarni gives your AI a memory it can read on demand.

How is this different from ChatGPT Projects or Claude Projects?

Projects upload static files. Hjarni is a live knowledge base your AI reads from in every conversation. You write once. Your AI catches up automatically.

How is it different from Notion or Obsidian?

Notion is a workspace with databases and page-building. 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.

Is my data safe?

We don't train AI on your data. Your AI only sees what you authorize through MCP. Notes are Markdown, so you can export and walk away at any time.

Can I export my notes?

Yes. Notes are Markdown. Export everything as a ZIP at any time. No lock-in.

How big is Hjarni?

Solo developer, bootstrapped.
