I made Tim\u2019s Markdown Reader because I wanted a free, open-source app just for reading Markdown. I spend a lot of time working with AI coding agents, and sometimes I just want to open the files they produce and read them without opening an editor.<p>It\u2019s written in Swift and works entirely offline, including Mermaid diagrams. It has no accounts, telemetry or network requests.<p>You can click links to other Markdown files and open them in the same window, with back and forward buttons. It also has search, automatic reload when a file changes, light and dark modes, adjustable fonts and text size, and centred or full-width layouts.<p>It started as something I needed myself, but I\u2019ve since spent quite a bit of time refining it for public release. I wanted to keep it fast and minimal while making it feel like a proper Mac app, with attention to small details.<p>It\u2019s MIT licensed, and the app is Developer ID-signed and notarized by Apple. Requires Apple silicon and macOS 14 or later (tested on macOS 26 and 27).<p>This is my first public open-source release. Would be good to hear what you guys think!","title":"Show HN: A fast, offline Markdown viewer for macOS built in Swift","type":"story","url":"https://github.com/temir-dev/tims-markdown-reader"}
