Schema Designer

Updated March 1, 2026 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.

• Generate table definitions with appropriate column types from plain English
• Define primary keys, foreign keys, and relationship constraints
• Recommend indexes based on likely query patterns
• Output migration files for PostgreSQL, MySQL, and SQLite
• Identify normalization issues and suggest fixes
• Flag common schema anti patterns with explanations
