All you need for annotation

Infrastructure security and scalability

  • On-premise deployment: Install and run the platform in your own environment for full data control.
  • Flexible role management: Separation of access levels (annotator, PM, administrator) at the level of individual projects or the entire system.
  • High performance: Stable operation without delays, even with ultra-large datasets and complex project architectures.

Advanced annotation functionality

  • Spatial depth: Precise definition of layers and ordering of objects that overlap each other.
  • Logical relationships: The ability to create “parent/child” object hierarchies and support complex metadata structures.
  • Temporal tracking: Control of objects on the video timeline, including visibility states and unique identification across different media files.

Faster annotation

  • ML-assisted labeling: Use of machine learning for automation of routine operations and intelligent contouring.
  • Optimized workflow: Split long videos into fragments for parallel work, then merge them back cleanly.
  • Efficient navigation: Linear interpolation for object tracking, support for hotkeys, and the ability to import existing annotations.

Management and analytics in real time

  • Professional management: A well-designed interaction system between annotators and verifiers to guarantee quality.
  • Statistics through API: Access to work speed metrics and error frequency in real time.
  • Deep productivity analytics: Detailed reports on how the team spends time, so you can tune workflows quickly.
