Your data, in one place

A central place for your personal knowledge. Full control, fully customizable.

  • Node

    Every piece of knowledge is a node, and can be connected in a graph. It can be a note, a diary, or an event.

  • Aggregation

    Node can be aggregated and presented in different ways.

  • External services

    Information from external services can be imported and then connected, such as health data.

  • Fully customisable

    Write Lua, Javascript, HTML, CSS, create your internal database table. There is no limit.


Every piece of information is connected, whether it is a note, a contact, or an event.


Use Lua to program your own logic, either call an API, or generate custom report, it is your call


You own your data, nobody else, period. No selling to third-party, no advertising.
