Annotation Insights

Roboflow provides statistics on annotations associated with your workspace and projects. You can view annotation insights in the Roboflow dashboard and through the REST API.

On August 1st, 2023, we improved how annotation metrics are tracked. The Annotation Insights v2 endpoint provides annotation data from August 1st, 2023 and later.
