ReadyRunner is a ChatGPT (GPT-3 and GPT-4) powered AI assistant app that runs on your desktop or the web. It helps users write, code, learn, and be productive. ReadyRunner includes features like a prompt library and AI text editor, offering three chat types: Assistant chat, ScratchPad, and Document Chat.
Download the ReadyRunner app for Mac or Windows, or access it via the web. Select your preferred mode—Assistant Chat, ScratchPad, or Document Chat—to begin interacting with the AI. Utilize the prompt library for tailored responses and the global hotkey for immediate access.
The Dev plan is designed for users with their own OpenAI developer API key. Messages are processed using your key, meaning ReadyRunner does not impose message limits; however, you are billed directly by OpenAI for your API usage. Access is limited to the models available through your specific OpenAI API account.
GPT-3.5 is a widely used AI chat model from OpenAI capable of generating realistic text, assisting with writing and editing, and producing code.

A message is defined as a single prompt sent to the AI that results in a successful response. If a response fails to generate due to an error, it is not counted.
If you hit your message limit, you can wait until the following month, upgrade to a higher plan, or purchase additional message credits.
