About AI Training Work

AI training (also called data labeling or human feedback work) is the human side of how modern AI is built: people review and correct model outputs, evaluate research, and create gold-standard answers that models learn from.

This role places experienced tax professionals at the center of that work—your technical judgments will improve the correctness and reliability of AI-generated legal research.

• 100% remote, flexible part-time work that can fit alongside other professional commitments.
• Entry to advanced projects exist across the platform; subject-matter expertise is often rewarded with higher pay.
