Why AI training matters

AI models learn from human examples and feedback. Work like this — labeling, rating, and evaluating responses — directly shapes how assistants handle professional tasks and keeps models helpful, safe, and accurate.

This role sits at the intersection of product quality and user privacy: you’ll use real business email history to judge whether model outputs are relevant, personalized, and trustworthy.

The role

As a Business Account Rater you will evaluate AI-generated text responses intended for professional users and write clear, structured feedback that helps improve model personalization and decision-making.

You will use an active Google Workspace business account and its email history to judge whether responses are relevant, accurate, appropriately personalized, and free from unsupported assumptions.

• Employment type: Contractor, part-time.
• Engagement length: estimated 3–4 months.
• Work is fully remote and requires strict data privacy and confidentiality.

What you'll do

You will review AI responses in context of a business inbox, compare alternative model outputs, and select or rate the best response while noting quality issues and personalization errors.

• Evaluate responses for relevance, accuracy, helpfulness, and personalization using your Google Workspace account and email history.
• Compare multiple AI responses and choose which provides the better user experience.
• Identify weak personalization, irrelevant recommendations, and unsupported assumptions.
• Write clear, structured, well-reasoned feedback following project guidelines.
• Maintain data privacy and follow all confidentiality requirements.
