Data annotation FAQ
Common questions about our AI labeling services and how to get started.
Data annotation is the process of labeling raw data — images, video, text, audio, or sensor data — so machine learning models can learn patterns. AI teams need human-verified labels because production models require accuracy, consistency, and edge-case coverage that automated tools alone cannot guarantee.
