YouTube ID→Name 変換コントローラ is a Chrome extension designed to improve the readability of YouTube Live chat by automatically converting user handles into their corresponding channel names. This tool addresses the common issue where @userhandles are displayed in the chat, making it difficult for viewers to recognize who is speaking. By replacing these handles in real-time, the extension allows for a more intuitive interaction among streamers, moderators, and viewers.

The extension supports various chat formats, including normal chat, member chat, and super chat, ensuring that all @handles are consistently displayed as channel names. Users can easily toggle the conversion feature on or off through the extension's popup interface. It is compatible with multiple operating systems and Chromium-based browsers, making it a versatile tool for enhancing the YouTube Live chat experience.
