Building domain-specific AI chatbots with Claude (gregwilson.tech)

A developer has announced the creation of four specialized AI chatbots, each designed to provide expert knowledge in narrow fields: jazz, Porsche, watches, and celiac disease. These chatbots, including JazzQuery and RennQuery, offer precise information and politely decline unrelated requests. The underlying technology utilizes a shared architecture and a two-model system where a lightweight model (Claude Haiku 4.5) filters incoming queries to determine their relevancy before escalating them to a more sophisticated model (Claude Sonnet 4.6) for responses, effectively managing operational costs. This approach is significant for the AI/ML community as it demonstrates an efficient way to deploy domain-specific expertise without the high costs typically associated with more general models. Each bot utilizes curated knowledge bases, including a local mirror of Wikipedia and specific databases pertinent to their domains, ensuring accurate and up-to-date insights while minimizing expenses. By leveraging selective web searches and local indexing, the model significantly reduces potential inaccuracies often seen in general search algorithms, reinforcing the importance of curation in AI responses. The project not only showcases technical innovation but also serves as a practical framework for developing similar domain-focused applications.
