vancenceho/simple-rag-app ? reverse-engineered prompt

Build me a simple web chatbot called Raggy that uses Google Vertex AI and Wikipedia to answer questions with retrieval augmented generation.

I want a clean, easy to run app where it pulls in Wikipedia pages, turns them into chunks, creates embeddings, and uses that knowledge to answer questions in a helpful way. It should feel like a friendly tech assistant, with a simple chat interface I can open locally in my browser.

Please make it work with my Google Cloud project details, my region, and my service account JSON key, and keep the setup straightforward so I can install the dependencies and run it with one command. If you need current library or Vertex AI setup details, look them up online first.

Also include a nice default experience so it works well out of the box, with sensible error handling if credentials are missing or the app can’t reach Wikipedia or Google Cloud.
