MD Formatter — Markdown & llms.txt Viewer

The web is being rewritten for AI — and it's worth reading. Documentation sites now publish a .md version of every page. Thousands of sites ship an llms.txt: a hand-curated map of their docs, written for language models. It's some of the most useful text on the web. Your browser shows all of it as a wall of raw monospace. MD Formatter fixes that. Open any Markdown file or llms.txt and it's already formatted — the moment the page loads. No button to press, no setup, no list of sites to maintain. ━━━━━━━━━━━━━━━━━━━━ BUILT FOR LLMS.TXT ━━━━━━━━━━━━━━━━━━━━ An llms.txt isn't an article — it's an index. MD Formatter recognizes the format and renders it as one: • Every entry becomes a card: its title, the author's note, and where it points • Sections stay grouped, with a link count for each • The "Optional" section starts collapsed, just as the spec intends • Links to other .md files are marked — follow them and they render too • "Copy section" puts any block back on your clipboard as clean Markdown, ready to paste into your AI assistant or agent Switch between the index, the full document and the raw source with one click. ━━━━━━━━━━━━━━━━━━━━ READS LIKE A REAL DOCUMENT ━━━━━━━━━━━━━━━━━━━━ • GitHub-flavored Markdown: tables, task lists, footnotes, strikethrough • GitHub-compatible heading anchors, so #links from elsewhere land in the right place • YAML frontmatter shown as a tidy metadata card • Relative links and images resolve correctly • Light and dark themes that follow your system — or pick one ━━━━━━━━━━━━━━━━━━━━ SMART, NOT PUSHY ━━━━━━━━━━━━━━━━━━━━ Markdown and llms.txt files render instantly. Plain text that only might be Markdown gets a small "Render" prompt instead of a takeover — so robots.txt, logs and JSON stay exactly as they were. Set any site to Always, Never or Auto from the toolbar. The original text is always one click away. ━━━━━━━━━━━━━━━━━━━━ PRIVATE BY DESIGN ━━━━━━━━━━━━━━━━━━━━ • No account, no analytics, no tracking • No server — the extension sends nothing to anyone • Documents are sanitized before display, so hostile Markdown can't run scripts • Very large files stay as plain text unless you ask, so nothing grinds to a halt About the install warning: Chrome says this extension can "read and change all your data on all websites." To know whether a page is a Markdown document, it has to look at it. It checks each page's content type and steps aside immediately on anything that isn't a text document. Nothing it reads is stored or sent anywhere.

The renderer only loads when there's something to render. Made by an independent developer. Feedback and bug reports: vieira08davi38@gmail.com
