Treedome is a local-first, encrypted, note taking application with tree-like structures, all written and saved in your computer
Currently you can only try it by building it yourself, instruction here. https://codeberg.org/solver-orgz/treedome/src/branch/master/docs/building.md But .deb and nixpkgs update is planned to follow suit though! You can also try an outdated one in https://aur.archlinux.org/packages/treedome-bin
Tell me what you think about it!
This app is never intended to be used by multiple people. The way i sync right now is using a manual upload/download. The .note file is sqlite, but you should treat it as a note file for a single person.
