What does MostlyAI do?

MostlyAI is a data intelligence platform that helps organizations work with sensitive data safely. It provides tools to analyze real production data through an AI assistant that understands natural language queries, and it generates synthetic datasets that preserve the statistical properties of original data while removing any personally identifiable information. This allows teams to share and analyze data without privacy concerns.

The platform uses a proprietary TabularARGN model architecture to create high-fidelity synthetic data with built-in differential privacy. It offers four main data types: real-world data analysis, mock data for testing, synthetic data for safe sharing, and simulated data for modeling edge cases. The system can be deployed on-premises or in private clouds using Kubernetes or OpenShift, ensuring data never leaves the organization's secure environment.

MostlyAI serves enterprise teams and data scientists who need to accelerate AI development while maintaining strict data privacy standards. Use cases include training machine learning models without exposing sensitive customer information, creating realistic test data for software development, and enabling secure data collaboration between departments or partner organizations. Companies like Swiss Post and Erste Group use it to expand data access while complying with privacy regulations.
