Schema Designer

Describe your data model in plain English. Get back table definitions, column types, primary and foreign keys, indexes, and a migration file ready to run. No diagramming tools, no back-and-forth — just describe what you're building and get a schema.

Covers the three most common databases: PostgreSQL, MySQL, and SQLite. Includes normalization suggestions when your description implies redundancy, and flags common anti-patterns like storing arrays in varchar columns or missing indexes on foreign keys.

Good for early-stage projects where you need to move fast, and for developers who know what data they need but want a second pass on structure before committing to a schema.
