Why AI training and document review matters

AI systems learn from carefully prepared human examples. Document review specialists teach models how to interpret, extract, and judge information from Word and PDF files so models can perform complex paperwork tasks reliably.

This work is remote, often part-time and deadline-driven, and gives contributors direct, practical impact on how state-of-the-art systems behave.

The role

OpenTrain is recruiting a Word and PDF Document Review Specialist to perform structured reviews of source documents and model outputs using forms, templates, and rubrics. You will record evaluation ratings and produce clear written feedback so models learn from consistent, expert human judgment.

• Contract, part-time role — 20+ hours per week, remote (U.S. applicants only).
• Pay: $20–$55 per hour, paid per hour.
• Work involves document evaluation and text-generation feedback (label types: evaluation_rating and text_generation).

Your primary responsibilities are reviewing documents against project guidelines, explaining judgments, and keeping quality high and consistent across repeated tasks.
