Chatbase (reference) - Next.js, FastAPI, OpenAI, PostgreSQL - AI SaaS Architect

A fictional AI customer support platform modeled on the workflows shown by Chatbase. The reference architecture combines a Next.js dashboard, Python/FastAPI backend, OpenAI API, and pgvector-based RAG for knowledge-grounded responses. Designed capabilities include document ingestion, semantic retrieval, agent configuration, human handoff, conversation analytics, and CRM integrations. The proposed system uses tenant isolation, background processing, evaluation datasets, and citation-aware responses to improve support accuracy, reduce manual work, and maintain reliable AI behavior.
