modekun is a free Chrome add-on developed by momochi. It is designed to automatically hide comments from live chat trolls. Currently, it supports platforms such as Youtube, Mildom, and Twitch. The add-on includes a "repeat words filter" that effectively works in Japanese.

modekun offers 5 types of vandalism control, including continuous throwing, word repetition, NG word (filtering specific words), character limit, and posting frequency. All the operations are executed directly on the browser, ensuring that no data is sent to any external server.

The latest version, 2.0.0, fixed a bug related to saving parameters correctly. It also introduced a new option called "Use common parameters" that allows the use of common settings regardless of the streamer. The add-on now supports Manifest V3, resulting in improved performance.

Overall, modekun is a useful tool for streamers and content creators who want to maintain a clean and moderated live chat experience. It effectively filters out trolls and prevents disruptive behavior during live streams.
