Image Caption Reviewer – English at Mercor

Image Caption Reviewer (English) | $30/hr | Worldwide Remote

Join a quality assurance initiative focused on improving AI-generated image captions. In this role, you will carefully evaluate captions produced by AI systems, comparing them against source images to identify inaccuracies and flag defects with precision.

What You'll Do

• Work through a structured set of images, reading each AI-generated caption in full against its corresponding image
• Identify and log all substantiated defects, including incorrect objects or counts, wrong colors, misread in-image text, and unsupported claims
• Treat the image as the ground truth and apply careful, methodical review rather than prioritizing speed

What We're Looking For

• Native-level English proficiency
• Strong attention to both visual and textual detail
• Patience and thoroughness — the ability to check captions line by line against what is actually depicted
• No specialist degree or technical background required

This is a great opportunity for detail-oriented individuals who take pride in accuracy and want to contribute to the improvement of AI systems.
