We’re looking for UK or Europe-based generalist experts to help train and evaluate frontier AI models. In this role, you’ll review and assess a wide range of everyday professional content — documents, slides, spreadsheets, and other written materials — judging them for quality, accuracy, clarity, and completeness. Your feedback directly shapes how AI systems reason about and produce real-world work product. This is a great fit if you’re a sharp, detail-oriented generalist who’s comfortable moving across different formats and subject areas. You don’t need deep specialization in any one field — strong judgment, careful reading, and clear written reasoning matter most. What you’ll do * Review and evaluate documents, slides, spreadsheets, and similar materials for quality and correctness * Provide clear,



well-reasoned written feedback and ratings * Compare and rank AI-generated outputs against defined criteria * Flag errors, inconsistencies, and gaps in reasoning or formatting What we’re looking for * Bachelor’s degree (minimum requirement) * Based in the UK or Europe * Excellent reading comprehension and written communication in English * Strong attention to detail and sound judgment across varied subject matter * Comfort working independently across common productivity tools (docs, slides, sheets) No prior AI or machine-learning experience is required — we’ll provide the guidelines and context you need to succeed.
