Alternative extension to do something similar, but using VSCode's native notebooks: https://marketplace.visualstudio.com/items?itemName=jaaxxx.l.... It's more tailored to crafting long-form few-shot prompts, rather than a single text box. Think ChatGPT playground but with a text editor interface that isn't absolutely terrible.

Nice part about that one is no separate server, no telemetry, and the backing file format is simple JSON you can directly import from your production application. However the range of supported models is smaller (basically only LLaMa-style and OpenAI-style interfaces are supported).

I don't understand what the use case is here at all. It saves prompt parameters as JSON? Is that it?

VSCode is a good target for single-player editing, and I can see something like this being helpful, but what does a collaborative experience look like, eg if you have a team of folks all working on the same prompts?

So I guess the idea is that you do your experimenting and iteration with this, then plug the config into your app?

It contains telemetry but it's not clear whether it collects your prompts or not
