About AI training and why this work matters

AI training (also called data labeling, data annotation, or human feedback work) is the human side of building artificial intelligence. People annotate code samples, rate responses, and categorize technical content so models learn to produce accurate and safe outputs.

This project focuses on code and technical writing: your annotations will help improve developer tools, educational materials, and research datasets that power next-generation software and learning applications.
