SwiftieGPT is a chatbot built using DataStax Astra DB and powered by conversational AI. It was designed to answer any questions about Taylor Swift and is constructed in two parts: a data ingest script that creates the knowledge base, and a web app that provides the conversational experience. The application uses Next.js, LangChain.js, Cohere, OpenAI, and DataStax Astra DB for its development. It's deployed to Vercel and can be accessed at https://www.tswift.ai. The source code is available on Github.
