Fountain Notes

Fountain Notes opens to a blank note so you can get an idea out before it slips away. No formatting maze. No folders to manage. No decision fatigue before the thought is even written. Write the note, file it away, and move on. Fountain Notes keeps old notes organized automatically and hidden from view until you need them. Search and the drawer are there when you want to find something, but they do not crowd the writing surface. Built for quick ideas, tiny reminders, quotes, fragments, and the little thoughts that usually vanish while you are deciding where they belong. Fountain Notes is intentionally small: - Blank note first - Fast local saving - One thought at a time - Clean search - Calm history drawer A quiet place to catch the thing and keep going.
