Superpower ChatGPT is a Chrome extension that provides additional functionality to the ChatGPT user interface. The tool allows users to select and export any number of their chats into multiple formats, such as .txt, .json, .md, etc. It also allows users to search through all their previous chats and highlight results for quick review. The tool boasts of having over 190 different languages and allows users to change the ChatGPT response language with one click. Users can sync a copy of all their chats locally to their computer and have full control over it. Other features include adding history to user input, pinning important messages in each conversation and quickly accessing them using a quick navigation sidebar, and a prompt library. The extension does not save any of the user's conversations in the database, and the developer assures users that they will never sell user information.
