ReadyRunner is an AI assistant application powered by ChatGPT (both GPT-3 and GPT-4) that can be utilized on your desktop or through a web interface. This tool is designed to enhance your writing, coding, learning, and overall productivity. With the ability to set a hotkey, you can easily summon ReadyRunner from any location on your device, enabling you to pose questions without interrupting your current workflow. In this application, prompts are communicated as a "system message," a feature of the ChatGPT APIs that isn't present on the ChatGPT website, which allows for more nuanced control over the type of responses generated by the assistant. These prompts serve as versatile mini tools for tasks such as translation, summarizing text, coding, debugging, and even character development. Additionally, the interface is designed so that each message you send glides to the top of the window, allowing responses to appear below them, thus creating a more user-friendly reading experience compared to other systems where messages stack from the bottom. This thoughtful design not only streamlines interactions but also enhances your overall efficiency while using the assistant.
