Hjarni is a personal knowledge management platform for organizing, searching, linking, and maintaining notes, containers, and tags.
What your AI can do hereConnector snapshot 2026-08-23
Connect Hjarni to ChatGPT or Claude with your own Hjarni login or an API key, and your AI can run 15 of its actions. 6 of those only read and change nothing. 1 can delete or send something that cannot be undone, so those need a boundary you set before anyone runs them.
Hjarni also publishes its own MCP server, which is a second way in. Vendor documentation
This describes what Hjarni supports, which is one half of the picture. Where you
start depends on the task and on how much you have handed over before, and no page can
tell you that from a count.
BUILT-IN AI Not yet checked against the vendor documentation. Absence of a confirmation here is not evidence the app lacks AI.
No event triggers. Every win in this app is invoked: you or an agent asks, an action runs.
