Seems quite cool! I definitely agree that there is a gap in the current RAG solution set for iterating on chunking and embedding strategies. Even the prompt chain for querying can be quite hard to adjust.

I tried out the tool itself and found the "define your schema" portion a bit confusing. I did eventually grasp it, but it took me a minute or two. The example curl requests on the page after I made my project were very helpful.

Thought I would expect that most folks doing RAG would probably prefer python that they could copy and past into a notebook.

Hopefully more people find it helpful!
