Generate a database schema from your app description

What is an AI database schema generator?

An AI database schema generator takes a natural-language description of your application and produces a complete database schema with collections or tables, fields, data types, indexes, and relationships. This tool supports MongoDB, PostgreSQL, and MySQL. You can also paste an existing requirements document, API spec, or user story and let the AI extract the schema from it.

What databases does this schema generator support?

The tool supports three databases: MongoDB (document model with collections, fields, and embedded documents), PostgreSQL (relational model with tables, columns, foreign keys, and indexes), and MySQL (relational model identical to PostgreSQL output). You can switch dialects after generating a schema to compare the relational vs. document model for the same application.

Can I export the schema to SQL or Prisma?

Yes. After generating a schema, three copy buttons appear: Copy JSON (exports the raw schema object), Copy SQL (available for PostgreSQL and MySQL — generates CREATE TABLE statements with column types, NOT NULL constraints, and index definitions), and Copy Prisma (generates a complete schema.prisma file with datasource, generator, and typed models).

How accurate is the AI-generated schema?

The AI produces reasonable starting schemas for most standard application patterns (e-commerce, SaaS, blog, CRM, etc.). Complex business rules, multi-tenancy patterns, and performance-critical index strategies should be reviewed by a database engineer before production use. Use this as a first draft that saves 30–60 minutes, not a final deliverable.

Is the database schema generator free?

Yes — completely free, no account required. There is a rate limit of 8 schema generations per hour per device to prevent API abuse. All schemas are generated fresh — nothing is cached or stored from your input.
