Best for ML teams needing representative training or test data without exposing production records. Engineering teams needing privacy-safe test data or PII-scrubbed text for lower environments and LLM pipelines. Enterprises needing to share or test with representative data that cannot leave a regulatory or contractual boundary. Regulated organizations that need synthetic test data generated fully inside their own infrastructure.
