PrettyMD is a polished desktop Markdown viewer built for people who read, review, and keep a lot of AI-written work.
Instead of opening long ChatGPT, Claude, or Codex outputs in a plain editor, PrettyMD turns Markdown into a clean reading workspace with rendered headings, tables, task lists, code blocks, Mermaid diagrams, and an outline for jumping through long documents. It is especially useful for product specs, implementation plans, research notes, agent reports, meeting summaries, and technical docs.
The app is designed for focused review: open individual Markdown files or whole folders, switch between light and dark themes, search across your workspace, keep multiple documents in tabs, and add comments without changing the original Markdown. Comments are stored in sidecar JSON files, so your source files stay portable and easy to share.
PrettyMD runs locally on Windows and macOS, making it a good fit for private notes, client work, and internal engineering documents. It is a small, fast tool for anyone who wants AI-generated Markdown to feel like a finished document instead of raw text.
Key features include folder browsing, tabbed reading, rendered Markdown, Mermaid support, code highlighting, document outline, task lists, search, comments, light/dark themes, and an offline-first desktop workflow.
