What is MostlyAI?

MostlyAI generates synthetic datasets that preserve statistical properties and relationships from your original data without exposing sensitive information. It's designed for organisations that need to share data internally, train machine learning models, or run testing without privacy risks. The tool uses AI to create realistic synthetic records that maintain the patterns and correlations of real data whilst removing personally identifiable information. This makes it useful for teams working across data governance, development, and analytics who need usable datasets without compliance concerns.

Key Features

Synthetic data generation

Creates statistically representative copies of datasets whilst removing sensitive information

Privacy-safe sharing

Enables teams to collaborate on data projects without exposing real personal or confidential records

Python client support

Integrates with existing data pipelines and workflows through Python libraries

Multi-purpose application

Supports data sharing, ML model training, QA testing, and self-service analytics

Educational resources

Provides blogs, videos, and reference materials to help teams understand synthetic data concepts

Pros & Cons

Advantages

  • Removes privacy concerns when sharing datasets across teams or external parties
  • Speeds up development and testing workflows by providing ready-to-use synthetic data
  • Maintains statistical relationships and patterns from original data, making synthetic datasets realistic
  • Available on a freemium model, allowing teams to try the tool before committing to paid plans

Limitations

  • Synthetic data may not capture all edge cases or rare patterns from the original dataset
  • Requires understanding of your data structure to configure generation effectively
  • Organisations handling highly sensitive or unusual data types may need custom implementation support

Use Cases

Sharing customer or transaction data with development teams without exposing real identities

Creating training datasets for machine learning models when real data is limited or restricted

Running thorough QA and testing scenarios without using production data

Enabling self-service analytics and reporting where business users need realistic data to experiment with

Accelerating data pipeline development by providing immediately available test datasets
