Synthetic data platform for privacy-preserving AI

Overview

Gretel.ai provides a synthetic data platform that lets developers and enterprises generate artificial datasets through APIs in order to build and test AI models without exposing real data. The platform creates synthetic data that mirrors the characteristics of real data, and includes tools to validate models and measure quality and privacy scores. It can be deployed for enterprise use and is available on the Google Cloud Marketplace, with a pay-as-you-go model based on the amount of data generated. Collaboration and project management features help teams work together. Gretel’s approach differs from competitors by offering a tightly integrated API-driven workflow, built-in quality and privacy validation, and cloud marketplace deployment, aimed at enabling fast, privacy-preserving data generation:** its goal is to help teams innovate faster while preserving data privacy.

Simplify's Take

What believers are saying

  • NVIDIA docs updated September 3, 2026 keep Gretel’s core technology shipping.
  • NeMo microservices give Gretel immediate distribution inside NVIDIA enterprise sales channels.
  • Privacy-compliance demand favors Safe Synthesizer for regulated customers handling PII and tabular data.

What critics are saying

  • gretel.ai redirects to NVIDIA; the standalone brand is effectively gone by September 2026.
  • Archived gretelai repositories kill independent product momentum and community adoption.
  • Competitors like MOSTLY AI and SDV target the same workflows, eroding differentiation quickly.

What makes Gretel unique

  • NVIDIA NeMo Safe Synthesizer preserves privacy with differential privacy and no record mapping.
  • NeMo Data Designer generates synthetic data from scratch or tiny seeds.
  • Gretel’s lineage combines multimodal synthesis with enterprise delivery through NVIDIA AI Enterprise.
