In plain English

AI chats often reply in a text format full of headings, lists, and snippets of code. MacMD Viewer is a Mac app that opens that text with colors for the structure, diagrams drawn from text, a side list that follows your place on the page, and the Mac quick preview. Buyers pay once and keep the app, because reading that format in an ordinary text box is clumsy. Showing the text and handling the purchase run with little daily work from the maker. That person still checks quality, helps customers, spreads the word, and looks at unusual files.
