Markdown Viewer for AI Agents

A fast, focused Markdown viewer for your Mac, built for the files you read but don't write: READMEs, documentation, and the plans, reports and checklists that AI coding agents create in your projects. Open a .md file and it's rendered instantly in a clean GitHub-style layout. Keep the window open and it updates live whenever the file changes, keeping your place in the document. If you're scrolled to the bottom, it follows new content as it's appended. LIVE RELOAD • Updates the moment a file is saved, including by editors and command-line tools that replace the file • Keeps your scroll position, or follows the end of the file like a log EVERYTHING RENDERED • GitHub Flavored Markdown: tables, task lists, strikethrough, autolinks • Syntax highlighting for dozens of languages, with one-click copy • Mermaid diagrams: flowcharts, sequence diagrams, Gantt charts and more • GitHub-style alerts (Note, Tip, Important, Warning, Caution) • YAML front matter shown as a tidy, collapsible panel • Local and web images MADE FOR READING • Table of contents sidebar that follows along as you scroll • Find in document, adjustable text size, light and dark themes • Word count and reading time • Check off task list items right in the viewer.
