Model integration
The separate Python AI service uses FAISS retrieval over the Bank of Korea financial glossary and GPT-based responses. Authentication, onboarding and product APIs are implemented in the Spring backend.
Implementation details
The Flutter app connects to a Java 17 / Spring Boot backend with Spring Data JPA and MySQL. A separate Python AI service documents a FAISS retrieval chatbot grounded in the Bank of Korea financial glossary, GPT-based portfolio support and youth-policy data APIs. These components are published in three linked repositories. The team README credits Dongju Kang with team leadership, planning and backend development.
Further improvements
Improve financial glossary retrieval and make the source context easier to inspect alongside educational explanations.
