Markdownly

About

Markdownly converts the current webpage into a GitHub-Flavored Markdown file and saves it to your Downloads folder. One click on the toolbar icon, one .md file.

It strips navigation, ads, and sidebars using Mozilla's Readability engine (the same engine behind Firefox Reader View), then converts the article body to Markdown with Turndown. Code blocks keep their language hints, tables become GFM tables, and images are preserved as remote links.

Features
  - One-click conversion of any article page.
  - GitHub-Flavored Markdown: headings, fenced code with language hints, tables, task lists.
  - Filename pattern: slug-YYYY-MM-DD.md (local date).
  - No host permissions. The extension only reads the active tab when you click.
  - No backend. No telemetry. Everything runs in your browser.

How it works
The extension uses chrome.scripting.executeScript to inject a content script into the active tab, run Readability on a cloned DOM, convert the result with Turndown, then download the Markdown via chrome.downloads.

Known limitations
Single-page apps that render content entirely client-side (Gmail, Twitter, Notion, Google Docs) often have no detectable article; the extension will show "Couldn't find an article on this page." See the docs on GitHub for the full list.
