Persistent Chat by ID is a lightweight, production-ready system for creating streamed AI conversations that can be saved, retrieved, and resumed using unique session IDs.
Chat Interface
The application combines the Vercel AI SDK with Neon Postgres to deliver durable message storage, fast streaming responses, and clean separation between API logic and UI. It serves as a reference architecture for building stateful AI-driven interfaces and can be extended into larger agent systems, RAG pipelines, and custom orchestrated flows.
