## Unlock your data for LLM fine-tuning and general model development

### Prevent sensitive data leakage

Automatically detect and de-identify dozens of sensitive entity types in free-text data to keep private information out of your models.

### Preserve data realism

Substitute sensitive entities with realistic synthetic data to create a "hidden-in-plain-sight" solution that enhances both privacy and model quality.

### Ensure HIPAA compliance

Partner with our expert determination provider to certify HIPAA-compliant data de-identification.

## Frequently asked questions

### How does Tonic.ai support AI and ML model training?

Tonic.ai enables teams to train, test, and validate machine learning models using privacy-safe data that reflects real world patterns without exposing sensitive information.

### Why is production data sometimes problematic for model training?

Production datasets often contain regulated or proprietary information that cannot be freely shared with data science teams or external partners. This creates delays, limits experimentation, and increases compliance risk during model development.

### Can Tonic.ai be used for repeated training and evaluation cycles?

Yes. Teams can use Tonic.ai to generate consistent or varied datasets on demand, making it easier to compare model performance, run experiments, and iterate without reintroducing privacy risk.

### How does Tonic.ai help improve model accuracy?

By preserving statistical properties and real world data behavior, Tonic.ai allows models to learn from representative data scenarios rather than oversimplified or overly sanitized datasets.

### How does Tonic.ai support governance and responsible AI initiatives?

Using synthetic and de-identified data helps organizations reduce exposure to sensitive information while supporting internal governance, audit requirements, and responsible AI practices.
