MD Formatter
Readable Markdown and llms.txt, the moment you open them.
More and more of the web is served as raw Markdown — documentation sites publish .md versions of their pages, and thousands of sites now ship an llms.txt. Your browser shows all of it as a wall of unstyled monospace text.
MD Formatter fixes that the way a JSON formatter fixes raw JSON: it notices what the document is and renders it, without being asked.
What it does
Nothing to configure
Open a .md file or an llms.txt and it is already formatted. No allowlist to maintain, no per-site setup, no button to press.
Built for llms.txt
An llms.txt is an index, not an article. It renders as a browsable set of link cards — sections, author notes, and the Optional block collapsed, as the spec intends.
Reads like a document
Headings with deep-linkable anchors, tables, task lists, footnotes, frontmatter as a metadata card, and a dark theme that follows your system.
Asks before it guesses
Markdown files and llms.txt render outright. Anything less certain gets an unobtrusive prompt instead — your robots.txt and logs are left exactly as they were.
Yours to switch off
Any site can be set to always render, never render, or decide automatically. The original text is always one click away.
Sends nothing anywhere
No server, no account, no analytics, no telemetry. The extension makes no network requests of its own — every document stays on your machine.
Permissions
When you install it, Chrome will say the extension can “read and change all your data on all websites.” That warning is accurate about what is technically possible, so here is what actually happens: to know whether a page is a Markdown document, the extension has to look at it. It checks the content type of each page you open and stops immediately unless the page is a text document.
It never sends what it reads anywhere, makes no network requests of its own, cannot modify network traffic, and runs no background process.
Full detail is in the privacy policy.
Make the next llms.txt you open readable.
One click to install. Nothing to configure afterwards.
