Markedin Parser av Jason Stonebraker

Markedin (.mi) is a file format tailor-made for the agentic web. It combines data (YAML) with prose (Markdown), plus templating to control the presentation — readable and writeable by humans and agents alike.

This extension renders .mi files inline in your browser. When you open a .mi file at a file:// URL or served from a web server, the extension parses the source and produces the formatted output — headings, lists, tables, code blocks, task lists — using GitHub Flavored Markdown. Your original .mi file is untouched.

What it renders

• Template expressions: {{key}}, {{nested.path}}, {{array[0]}}, {{#each}}, {{#if}} / {{else}}, {{> partial}}
• GitHub Flavored Markdown: tables, strikethrough, autolinks, task lists
• Light and dark themes (follows your system preference)

Privacy

• Zero permissions requested
• No network requests, no analytics, no telemetry
• Nothing leaves your browser

This is the open-source reference Firefox implementation of the .mi format. Parsers for Node, Go, and Python are available in the same repository.
