This is the workflow I ended up with:

- LLM call to brainstorm ideas

- second LLM call to rate ideas from 1 to 10

- create cards for each idea, sorted by rating

I also added the ability for users to iterate on the cards via a chat interface (similar to how you can iterate on UIs generated by tools like bolt or v0).

I built it with AI SDK, NextJS and assistant-ui. I spent most of my time on prompt engineering and a little bit on making the UI look nice.
