Twitch No Cancerino is a free Chrome add-on developed by Benjamin Maisonnas that aims to improve the quality of Twitch chat by removing unwanted elements. This add-on adds a right-click menu option to toggle cancer on/off in Twitch's chat, providing users with a cleaner and more enjoyable chat experience.

When activated, Twitch No Cancerino removes all emoticons and hides cancer messages, except from subscribers. Additionally, it checks chat messages from regular Twitch users for signs of bad quality posting, such as repeated words, excessive capital letters, and an abundance of emotes. These low-quality messages are then displayed with partially transparent text, making it easier for users to identify and ignore them.

Twitch No Cancerino also offers GIF examples to demonstrate its effectiveness in curing robotic cancer and reducing chat spam. With this add-on, users can enjoy a more streamlined and engaging chat experience on Twitch.
