Gretel

Gretel is a synthetic data platform that enables developers and data scientists to generate privacy-preserving artificial datasets that mirror the statistical properties of real data. The platform provides APIs, SDKs, and pre-built models for generating synthetic structured and unstructured data, supporting use cases including AI model training, software testing, and analytics without exposing sensitive information. Gretel's tooling includes differentially private learning, data transformation, and quality evaluation — allowing enterprises in regulated industries such as healthcare and finance to safely share and collaborate on data. The company was archived on GitHub in February 2026 following wind-down activities.
