AI tools generate markdown constantly — Claude, ChatGPT, Cursor. No native place to read it beautifully on Mac. Finder shows raw text. Opening a coding editor just to read a file is a workaround, not a solution. Marklet is a local-first markdown workspace. Open any folder, browse your files, read them rendered beautifully. Themes, syntax highlighting, TOC, source editing. No database, no cloud, no account. Your files stay yours.
