About AI training work

AI training (also called data labeling or human feedback work) is the human side of building artificial intelligence: people review, rate, and correct model outputs so future models get better. This work is highly accessible, often remote, and flexible — a strong fit for professionals who want part-time, impactful work.

Contributors directly shape how models perform in their fields by evaluating accuracy, identifying errors, and giving structured guidance that informs model improvements.

• 100% remote work — contribute from anywhere.
• Flexible part-time hours that can fit around other commitments.
• Work that influences real AI systems in biology and environmental science.
