About MuM

Your Markdown lives in a dozen folders. Most of the time you don't want to write - you just want to read one section. Every Markdown tool is a writing app with a preview pane. MuM is the opposite: a native macOS reader with no web engine inside - all AppKit. Several projects open at once, each remembering where you stopped. Cross-project search. Typesetting tuned for CJK as well as Latin. ~0.3s cold start, 1.7 MB download, 100+ fps scrolling a 5 MB document. Open source, MIT.
