YouTube Live Chat Comments Only is a free Chrome add-on developed by 犬々. It allows users to hide all elements except comments in the YouTube live chat. This add-on is designed to create a more anonymous and focused viewing experience by removing icons and names from the chat section.

After applying the add-on, the screenshots provided show a comparison of the chat section before and after installation. The first two screenshots display the chat section before installation, while the third and fourth screenshots show the chat section after installation, with the chat enlarged for better visibility.

It's important to note that this add-on only affects the visibility of the chat for users who have installed it. Those who have not installed the add-on will see the chat section as usual. While users' own icons and names are still visible in the chat input field, they will be hidden in the chat display section, making it less user-friendly for actions such as retracting messages.

Please note that this add-on has only been tested and confirmed for the Japanese language and location settings. Additional details and update history can be found in the options page after installing the extension.
