Successful reviewers do not simply validate AI-generated conclusions—they critically evaluate them. Your role is to verify evidence, challenge unsupported assumptions, and ensure AI systems learn from accurate, reliable, and well-supported information.

Your expertise will help build more reliable, trustworthy, and human-centered AI systems.

At TrustScale, we believe AI improves when people are willing to question it.

As an AI Fact-Checking & Response Evaluation Reviewer, you will evaluate AI-generated responses, verify evidence, challenge unsupported conclusions, and help define the standards that AI systems learn from.

Good AI is built on good judgment.

TrustScale is seeking experienced French -language professionals to evaluate AI-generated responses, verify factual accuracy, assess supporting evidence, and help define the quality standards that AI systems learn from.

As an AI Fact-Checking & Response Evaluation Reviewer, you will review AI-generated content, determine whether conclusions are supported by evidence, identify reasoning gaps, challenge unsupported claims, and help improve the reliability of next-generation AI systems.

This is not a traditional annotation, translation, or data-entry role.

This role requires individuals who are comfortable questioning conclusions, investigating claims, and making evidence-based decisions—even when those decisions differ from AI-generated recommendations.

The strongest reviewers are naturally curious, skeptical of unsupported claims, detail-oriented, and confident applying their own judgment when evaluating information.

This is a remote freelance opportunity with flexible hours and payment in USD.

We are seeking a small group of experienced reviewers to support upcoming AI quality initiatives. Applications are reviewed on a rolling basis.

Ability to pass a qualification assessment in English/French.

Due to the specialized nature of AI quality work, selected candidates will complete a qualification process before onboarding.

This process may include guideline reviews, platform training, UI navigation exercises, knowledge assessments, fact-checking exercises, and project simulation tasks designed to evaluate quality, accuracy, consistency, critical thinking, decision-making skills, and overall readiness for project work.

All qualification activities are unpaid and form part of the candidate evaluation process. Successful completion does not guarantee project placement, as final selection is based on assessment performance, demonstrated commitment, consistency of quality, project requirements, and available capacity.

TrustScale seeks contributors who consistently deliver high-quality work, actively engage with project requirements, demonstrate reliability, and maintain strong reviewer judgment throughout the project lifecycle.
