What is freelance annotation?

Freelance annotation involves labeling or tagging data—such as text, images, audio, or video—to help train artificial intelligence and machine learning models. Annotators work independently, usually on a per-task or per-project basis, for companies needing accurate data labeling. Common tasks include drawing bounding boxes on images, classifying text, or transcribing audio. Freelancers can work remotely and often choose their own schedules, making it a flexible job option. Accuracy and attention to detail are crucial for success in this field.
