Cynthia generates HIPAA-safe synthetic datasets that mirror your production schemas — so your team can build, test, and train ML models without waiting for de-identified data.
Everything you need to generate production-realistic synthetic data at scale.
Upload a CSV, JSON, or Avro schema and Cynthia will infer types, cardinality, and relationships.
From schema to synthetic dataset in three steps — no PHI required at any stage.
Import a CSV, JSON, or Avro schema — or connect directly to your database. Cynthia reads your field names, data types, and relationships without ever touching your real records.
Set volume, demographic distributions, and domain-specific parameters. For healthcare, dial in diagnosis codes, age ranges, and comorbidity patterns.
Download as CSV, JSON, or FHIR R4. Pro and Enterprise plans support direct export to S3, your data warehouse, or an existing FHIR server.
Cynthia generates large amounts of synthetic data that resemble real-world data, enabling data engineers to work without compromising user privacy.
Populate your local database with realistic data for development and testing purposes.
Boost dataset quality and drive unparalleled ML performance without exposing real data.
Generate data that fits your needs — names, addresses, ICD codes, FHIR resources, and more.
Integrate Cynthia into existing workflows with our API, CLI, and direct pipeline exports.
Generate as much data as you need, when you need it — Cynthia scales with your business.
Statistically accurate data that ensures your synthetic records are as close to real-world as possible.
The Cynthia plugin runs entirely locally — no account, no API key, no data leaving your machine. When you need cloud scale, team access, or automated pipelines, one API key unlocks it all.
