MarkDown Reader is a free, lightweight viewer for Markdown files. Double-click any .md file and read it beautifully rendered — no editor chrome, no distractions, just your document. It also turns a checklist into somewhere to work. Tick a task and the change is written straight back to the file, one character, instantly. Add a note to any item and it is saved as an ordinary indented bullet, so every other Markdown tool still reads it. On the Mac, drag a file onto an item to attach it, and click the chip to open it again later. Nothing is locked in a database.
