Intergrid is an online notes and outline app, inspired by Indigrid.
Intergrid's goal is to transfer the focused note-taking functionality to the Web, enabling users on all platforms to use it.
A working prototype is available right now. Beware: the prototype contains a handful of unfixed bugs. I've decided against fixing them, in favor of engaging with other promising projects, some of them related to my experience with working on the app.
