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 You can also try an outdated one in https://aur.archlinux.org/packages/treedome-bin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!
Internally no, this uses tiptap's document structure, which is more complex than markdown but easier to expand with new feature, if any.
Does that mean TreeDome is the only program that can meaningfully open the notes file?
Is there a mobile client planned? Or do you know if any current mobile apps are able to read the TreeDome notes file?
Yes, treedome is the only program that can meaningfully open the notes file. This is because the content of the file is always encrypted and stored using sqlite (single file database library). I'm not that good with mobile and I still need to think about how it will be used in mobile. For example, the tree structure is definitely weird if used in mobile.
