Show HN: AI support chatbot with RAG and citations – one back end file, no infra (github.com)

9 points by anupsing_ai 3mo ago ↗ HN

Upload markdown docs, get a support chatbot that answers with citations. The entire backend is one JS file — storage, search, and conversation history are handled by the runtime.

Stack: Next.js + OnCell + OpenRouter.
