Up is a free Chrome extension developed by isaiahpan that enhances your stream chat experience. It is designed to help you recall chat history, chat faster, and easily access commonly used inputs.

One of the main features of Up is its chat history recall function. With this feature, you no longer have to worry about missing parts of the stream due to emote search. It eliminates the need to scroll back through the chat to find previous messages, as you can simply press the up arrow key to see your previously typed messages.

In addition, Up allows you to save your most commonly used inputs, making it easier to access and send them without having to type them out every time. This is particularly useful if you frequently use stickers or have trouble remembering their names.

For YouTube users, Up offers an additional feature called the filter. By opening the filter and clicking on a chat message typed by someone else, you can quickly see chat messages grouped together. This is especially helpful if you want to know which Holocure option chat is pushing for.

It's worth noting that Up is only applied in three locations: YouTube live chat, Twitch chat, and chatGPT. This ensures that the extension is focused on enhancing the chat experience in these specific platforms.

Overall, Up is a handy Chrome extension that improves your stream chat experience by providing chat history recall, faster typing, and easy access to commonly used inputs. Whether you're an avid streamer or a dedicated viewer, Up can help streamline your chat interactions.
