Markdown Companion reads what your AI writes
A local browser extension that renders Markdown files cleanly and shows line-by-line changes as they are saved.
Field notes
The extension is designed around local Markdown folders rather than a hosted documentation workspace. Its described workflow watches a file on disk and can show a GitHub-style inline diff before reloading changes, including edits made by an editor or coding assistant. The page lists support for five Markdown-related file extensions, Mermaid diagrams, KaTeX math, folder navigation, scroll-spy outlines, and sanitized embedded HTML. It also describes light, dark, sepia, and high-contrast reading modes.
