Christoph Beck // Interactive Documentation: Creating a Secure, Elixir-Powered RAG System

In the latest Alchemy Conf talk upload, Christoph Beck addresses the persistent gap between library creators and adopters regarding documentation. Even well-maintained docs can be difficult to navigate in larger projects, leaving developers hunting for the right information.

Through practical demonstrations, Beck shows how Retrieval Augmented Generation can bridge this divide by allowing users to chat directly with library documentation. He covers the technical implementation and explains why Elixir’s engineering strengths make it well-suited for production AI systems as they evolve from simple experiments into complex, multi-component architectures. He also addresses security considerations, treating LLMs as “overly enthusiastic interns” who require careful supervision, and covers practical concerns such as access control and usage tracking.

The talk concludes with the announcement of Exmeralda.chat, a community service that ingests Hex packages, allowing developers to chat with any Elixir library’s documentation without individual setup.
