Soaked is a prompt engineering IDE that focuses on visual prompt chaining with a graphical interface. It is currently in beta, but active development has ceased.
Soaked provides a graphical interface for chaining prompts together, where you can easily see how different components flow together. It also provides a lower level prompt view with the option to generate multiple completions at once. It also provides a cost estimate for completions. It currently supports GPT3 and requires an OpenAI key to use.
