MarkdownObserver tracks a folder for new and updated Markdown files and opens them as beautifully rendered, live-updating documents — perfect when AI coding assistants like Claude Code or Codex generate plans, design notes, code reviews, or status reports.
See what changed at a glance: gutter markers and a before/after comparison view highlight every edit as it happens.
