The Unofficial Whatnot Stream Assistant is a Chrome extension designed to enhance Whatnot streams. It allows Whatnot streamers to configure Discord-like slash commands in their streams, providing a more interactive experience for viewers.

With this extension, streamers can enable various commands that viewers can use during the stream. For example, streamers can set up a command that allows viewers to look up the price of a card without leaving the stream. Additionally, streamers can create a simple "/rules" command that will respond with the rules of the game being played.

It's important to note that this extension is not officially maintained by Whatnot. However, it provides a useful tool for streamers who want to add more interactivity to their streams and engage with their viewers in new ways. The Unofficial Whatnot Stream Assistant is available for free on the Chrome platform.
