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.

• Pay: $20–$55 per hour, paid per hour.
