Twitch Chess move filter is a Chrome extension designed to hide chess moves and terms from Twitch chat. It is particularly useful for chess streamers who do not want to be spoiled by their viewers. With this extension, viewers can discuss the current position without ruining the game for the streamer or anyone else who has the plugin enabled.

The idea for this extension came about when the developer, kuijvenhovenssj, wanted to stream their chess games on Twitch.tv but noticed that people would often post moves in the chat. To address this issue, they created Twitch Chess move filter, allowing for a more enjoyable and spoiler-free streaming experience.
