Medium Infinity Reader is a Chrome add-on developed by yiyu0x. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This free software aims to redefine the 'referer' in the HTTP header to allow users to read unlimited articles on Medium.

The program works by modifying the HTTP header and changing the referer to Twitter. By doing so, it bypasses the article limitation set by Medium, allowing users to browse through Medium articles without any restrictions. It is important to note that this add-on does not engage in any form of cracking or illegal activities. The developer encourages users to support the original content creators by purchasing their articles through legitimate means.
