Schema Writer

Designing database tables by hand is tedious. You know what columns you need, you know the relationships, but writing out CREATE TABLE statements with proper types, constraints, and indexes takes forever. Describe your data model in plain English and this tool writes the SQL for you. Supports PostgreSQL, MySQL, and SQLite.

One command. Zero config. Just works.

Quick Start

npx ai-schema "users with email, name, and posts with title and body"
