About AI training work

AI training (also called data labeling or human feedback work) is the human side of building modern AI: people review model outputs, rate responses, and create examples that teach models how to behave. This work is remote, flexible, and accessible—contributors directly shape how AI performs in real-world scenarios.

The role

As a Business Account AI Response Rater you'll evaluate AI-generated responses written for professional users by comparing them with a user's corporate Gmail history and account activity. Your judgments will focus on relevance, accuracy, helpfulness, and how well responses are personalized to the business context.

This is a contractor, part-time role requiring about 20+ hours per week. You'll produce structured evaluation feedback that helps improve model behavior in professional communication settings.

What you'll do

• Review AI-generated responses using a business Gmail history and relevant account activity.

• Compare multiple model outputs and select or rate the stronger user experience.
• Write clear, detailed evaluation feedback that supports model improvements.
• Follow project guidelines to keep evaluations consistent and high quality.
• Handle personal business account information with confidentiality and privacy awareness.

• Bachelor's degree or equivalent practical experience.
• Ability to work independently in a remote, contractor role and commit to ~20+ hours/week.
