Why AI training and data labeling matters

Human review and high-quality reference content are essential to teach modern AI systems how to write and reason. This work is remote, flexible, and accessible: people with strong language skills and attention to detail can build steady freelance income and shape how state-of-the-art models behave.

This project sits at the intersection of language expertise and AI safety: your corrections, rewrites, and ratings directly improve model quality and reduce errors like mistranslations, bias, and factual mistakes.

The role

You will work as a Catalan Language Review Specialist, evaluating AI-generated Catalan outputs and producing high-quality Catalan reference answers. Tasks include detailed evaluation, written feedback, and creating rewrites and example responses that model best-practice Catalan usage.

• Create high-quality Catalan reference content for general knowledge, customer support, education, translation and culturally sensitive topics
• Detect hallucinations, bias, ambiguity, unsafe claims, and unnatural phrasing
• Identify mistranslations, register issues, regional variation problems (including Valencian and Balearic), and Castilian interference
• Write rewrites and example answers that demonstrate best-practice Catalan usage
• Rank model responses and provide detailed, actionable feedback

• Strong professional English, minimum C1, for detailed written feedback
• Deep understanding of Catalan grammar, spelling, punctuation, pronouns, verb forms, tone, idioms, and style
• Comfort handling standard Catalan plus Valencian and Balearic usage and formal vs informal registers
• Bachelor's degree or equivalent professional experience in a related field
• Prior experience in AI data training, translation QA, editorial QA, localization QA, or rubric-based evaluation is strongly preferred
