MD Beautifier: Markdown Viewer & Formatter

Read AI markdown beautifully. Render, check and export .md files. 100% local: nothing you open leaves your device.

100% local. MD Beautifier collects no data, and nothing you open is ever sent to a server. Read the Markdown your AI writes. Claude, ChatGPT and Cursor hand you README files, AGENTS.md, CLAUDE.md, plans and reports as .md files. Open one in Chrome and MD Beautifier turns the plain text into a clean, readable page. WHAT YOU GET • A calm reading view: table of contents, reading time, progress bar, GitHub alerts, tables, task lists and footnotes • Code highlighting for more than 45 languages, Mermaid diagrams and math (KaTeX) • Live reload with Change Glow: save the file in your editor and the page updates within a second, with every change highlighted • Markdown Doctor: checks the file itself (broken links, skipped heading levels, unclosed code blocks, mixed list markers, missing alt text), scores it and gives you a cleaned copy. Your file is never modified. • Snap Card: turn a section, code block or table into an image you can share • Save as PDF and download a single-file HTML page • Smart tables: sort, filter and copy as CSV • Light, dark and system themes, 6 accent colors, 4 typography presets, adjustable width and font size • Keyboard shortcuts for everything (press ? to see them) • Available in 33 languages PRIVATE BY DESIGN No account, no analytics, no tracking. Everything happens on your device. MD Beautifier only reads the Markdown pages you open: local files after you allow file access, and websites only after you enable them one by one. GETTING STARTED Chrome keeps extensions away from files on your computer until you allow it. After installing, a short guide shows you the one switch to turn on ("Allow access to file URLs"). It takes about ten seconds. Questions or ideas? hello@digitaltrafficlabs.com Made by Digital Traffic Labs.
