Show HN: LLM RAG-style coffee recommender (tinywaffle.co)

I roast coffee on the side and built a recommender (in a loose sense).

It's using Shopify's Hydrogen platform which uses Remix and GraphQL. The selections are used to query for tagged in-stock coffee and passes the results to OpenAI to pick one or generate a blend of coffee.

It's a RAG system without the vector DB.
