Looks pretty neat. There are other tools that I believe might do prompt chaining with a node like design as well. I haven’t had time to try them out, so I’m not sure if they are handled differently. Maybe you have seen them? One would be https://promptchainer.io/ and the other GitHub - FlowiseAI/Flowise: Drag & drop UI to build your customized LLM flow
I believe there are a few more, but I can’t find them in my bookmarks.
Langchain introduced me to the idea of chaining prompts. I’ve been experimenting with prompt chains for a while via the API, and they are fun to play around with to see what kind of output you can get.
