Hjarni - 2026 Pricing, Features, Reviews & Alternatives

Hjarni is a hosted Markdown knowledge base with a built-in MCP server. It gives ChatGPT, Claude, Cursor and other compatible AI clients access to the same saved notes, so project context can carry across conversations and assistants.

Keep decisions, research, briefs and runbooks in one place. Ask your connected assistant to search and read relevant notes before answering, or create and update notes as work progresses. A decision saved in ChatGPT can be read and updated in Claude or Cursor.

Write and edit notes yourself on the web or in the iOS and Android apps. Organize them with nested folders, tags and wiki-links, search the full text, and attach supporting files. Folder instructions give connected assistants your conventions for different projects. Version history records who changed a note and lets you restore an earlier version.

For teams, Hjarni provides a shared knowledge base with member management and viewer, editor and admin roles per folder. Each teammate can connect their own AI client to the same notes. Scoped agent tokens let you give an agent read or write access to selected folders. A documented REST API supports scripts, automations and custom integrations.

Notes remain plain Markdown. Import a Markdown or Obsidian ZIP, preserve its folders and links, and export your knowledge base when you need it. Data is hosted in Germany, and Hjarni runs the MCP server for you.

Start free with 25 personal notes, full MCP and API access, version history, import and export. Pro removes the personal note cap and adds more attachment capacity, email capture and shared personal folders. Teams provides a separate shared workspace with per-seat billing and 25 shared notes free to start.
