AfterImage is a Python library and CLI for generating synthetic conversational datasets using modern LLMs, offering both simple YAML-based configuration and a composable Python API. It's interesting because it bridges the gap between quick experimentation and production-scale dataset generation with features like structured extraction, persona-driven diversity, and preference pair generation.

Target audience: data engineers, ml-engineers, ai-researchers
