Every order belongs to a real customer, ships after it is placed, and totals its line items.
AI designs the schema and writes free-text fields; a deterministic engine generates the rows, so keys, totals and dates stay consistent at any size.
Customers, orders, payments and shipments that all reference each other correctly.
Skewed prices, realistic status mixes and correlated columns, instead of uniform random values.
Trends, seasonality and per-entity patterns for metrics, demand or sensor readings.
Every value is synthetic. No PHI or real personal records ever enter the platform.

Describe your data in plain English, or upload your SQL schema for PostgreSQL, MySQL / MariaDB, SQL Server and SQLite.
Check the tables, columns and rules the AI proposes, and adjust anything you like.

Synthetic data is artificially generated data that looks and behaves like real data but contains no real people or records, so it is safe to use for testing, demos and development.
Chatbots lose consistency well before thousands of rows. GenerateRealData uses AI for context and a deterministic engine to enforce foreign keys, distributions and cross-column rules at any size.
Yes, for prototyping pipelines, testing feature engineering and building demos. It is generated to look realistic; it is not a statistical copy of any real dataset.
