About AI Training Work

AI training is the human side of building artificial intelligence. People prepare and review examples that help AI models understand language, classify information, and produce more useful results.

Text annotation and review work can provide flexible, remote opportunities in a fast-growing technology field. Your attention to detail helps create consistent, high-quality data for analysis and model training.

The Role

OpenTrain AI is seeking Argentina-based freelancers for English text annotation and review. You will examine text that has already been annotated, verify whether the classification tags are accurate, and correct missing or incorrect tags when needed.

The work is performed in an online labeling tool and follows project guidelines. This is an entry-level, part-time contractor opportunity requiring less than 20 hours per week.

• Location: Argentina
• Language: English at minimum B2 proficiency on the CEFR scale
• Pay: $3.50 USD per hour
• Workload: Less than 20 hours per week
• Engagement: Part-time contractor

What You’ll Do

You will review English-language text and determine whether its existing classification tags accurately reflect the content. When tags are missing or incorrect, you will update them according to the project guidelines.

The goal is to deliver reliable, consistent labeled data that can support further analysis and AI model training. During the interview, you may also review short text snippets and select the classification that best represents each passage.

• Read and understand English text carefully
• Verify pre-existing classification annotations
• Correct inaccurate or incomplete tags
• Use an online labeling tool
• Follow project guidelines consistently
• Complete assignments reliably and meet deadlines

Requirements

This role is suited to detail-oriented candidates with strong English reading comprehension and dependable communication. Previous data-labeling or related experience is preferred, but familiarity with annotation tools is not required if you can learn new technologies quickly.

• Reside in Argentina
• Have at least B2 English proficiency according to the CEFR scale
• Demonstrate strong reading comprehension
• Have excellent attention to detail
• Be able to meet deadlines consistently
• Have good communication skills
• Previous data-labeling experience is preferred

Who Should Apply

• Detail-oriented English readers
