I have setup a self hosted note server[0] on Raspberry PI. Here's my workflow:

- Remembered a todo or note? Type note in your browser address bar with keyword 'pin' prefixed

    pin todo!pay the rent
    pin grocery!handwash
    pin watchlist!https://www.youtube.com/watch?v=j800SVeiS5I

- Note gets saved in markdown document like todo.md, grocery.md and watchlist.md. 'pin' is the keyword I have configured for my Pi server and browser thinks its a search engine.

- A http shortcut on Android when clicked shows a dialog box with todo.md contents.

- Edit/View notes using mapped network drive in your favorite markdown editor both on desktop/mobile. You can also view all the notes in your browser.
