Tidy Reader

A simple bookmarklet to tidy up articles for easy reading

Tidy is a simple open source bookmarklet that uses Mozilla’s Readability library to tidy up web pages for easy reading.

To install Tidy, simply drag the “Tidy!” link below into your bookmarks. Then click the bookmark to clean up an article page.



This bookmarklet may not work on all websites and browsers. You can troubleshoot issues by opening the Developer Console in your browser and checking if any errors appear when you click the bookmarklet.

The most common error is that a website or the browser itself is blocking third party code execution. This is commonly due to the connect-src Content Security Policy (CSP) used by some websites.
