All.4.One combines a note editor, code editor, and pin system in one macOS app. Features 4 independent note spaces, code formatting/minification (7 languages), HTML preview, dynamic variables (IP, dates). All in one unified experience for developers.
I built this because I got tired of juggling tabs: notes in one place, code formatters in another, random tools and searches everywhere. I wanted a single, native macOS “Swiss-army knife” I could open instantly and use for whatever the task is: writing, programming, cleaning data, crafting prompts, replying to emails, and quick lookups. It started as a personal scratchpad plus a few formatters, then evolved into a focused, dark-first workspace designed to reduce context switching and keep momentum.
