# Natural Language Postgres Guide

> Build a Next.js app to query PostgreSQL using natural language

An official tutorial from Vercel demonstrating how to build a natural language interface for PostgreSQL databases using the Vercel AI SDK and Next.js. It explains how to generate structured SQL queries, break down query clauses into plain-English explanations, and display results in charts and tables. It serves as a practical starter pattern for developer tooling and AI-powered internal analytics dashboards.
