Show HN: iMessage-data-foundry – Synthetic iMessage Data Generator (github.com)

A new tool called iMessage Data Foundry has been introduced, enabling developers to generate realistic synthetic iMessage and Address Book sqlite databases specifically designed for mock testing and demo applications. This generator constructs chat.db databases that closely mirror the macOS iMessage schema, providing customizable options to create personas and conversations using AI. Users can leverage local models for Apple Silicon or utilize external endpoints from OpenAI and Anthropic for generating conversation data, which includes support for various macOS versions and both group and one-on-one chat formats. This innovation is significant for the AI/ML community as it facilitates the development of applications interfacing with iMessage by providing a realistic dataset for testing iMessage analysis tools, exporters, and other demos requiring authentic chat experiences. The tool offers advanced features like AI-powered personas with distinct personalities, realistic timestamps, and placeholders for attachments. By streamlining the development process with comprehensive database schemas and generative functionalities, iMessage Data Foundry provides a valuable resource for enhancing testing accuracy and promoting innovation in AI-driven messaging applications.
