About AI training work

AI training (data labeling, annotation, and human-feedback work) is the human side of building modern AI. Contributors prepare and judge examples that teach models how to respond, reason, and personalize for real users.

This type of work is often remote and flexible, accessible to people without specialized degrees, and lets you directly influence how cutting-edge systems behave.

The role

You will be a Personal Account Rater on a personalization evaluation project. Using your own Gmail account and email-history context, you will judge whether AI-generated responses are relevant, accurate, helpful, and properly personalized.

This is a remote contractor, part-time engagement with an expected duration of 3 to 4 months. OpenTrain AI hires and manages the contract for this project.

What you'll do

Work through prompts and AI responses presented in English and use your personal Gmail history to judge personalization and contextual accuracy. Provide clear, structured feedback following project guidelines.

• Evaluate AI-generated responses using your personal Gmail history and activity.
• Judge relevance, helpfulness, accuracy, and quality of personalization.
• Compare alternative responses and select which gives the better user experience.
• Flag unsupported assumptions, incorrect personalization, and irrelevant recommendations.
• Provide objective, written evaluation feedback that follows project instructions and preserves privacy.
