to work on AI.
Use your subject knowledge, language skills, or careful judgment to evaluate AI and improve the data behind it. GroundTruth matches qualified contributors to paid project work.
Human judgment for better models and better data.
Assignments vary by project. Some require deep subject expertise; others reward careful reading, consistent decisions, and close attention to detailed guidelines.
Build evaluation material
Write challenging prompts, reference answers, grading rubrics, or test cases grounded in your field. The goal is to measure capabilities that matter in real use—not trivia.
Review multimodal data
Inspect text, images, audio, or video against a clear specification. Identify incomplete, unusable, or incorrectly labeled data before it reaches training or evaluation.
Audit quality
Review completed work, resolve disagreements, and flag ambiguous instructions or edge cases. Your feedback helps the whole reviewer group become more consistent.

We qualify people for the work each project actually requires, then provide the guidelines and calibration needed to contribute confidently.
