Overview

Writer Computer is a free, open-source markdown editor for macOS that opens the folders you already have. It's built with Tauri rather than Electron, so the download is about 6 MB, and it keeps itself up to date: it checks for a new version when it starts and once a day, and installs it when you say so. These pages cover what it reads, how it treats your files and how to use it.
