About the project

Laberu is a web tool for building model training datasets, covering both object bounding boxes and image captions.

Key features

  • Multi-user workspace — many annotators work in one project at the same time and can see who is on which item
  • Concurrency control — items in progress are locked so work never overlaps
  • Role-based access — separate permissions for project managers and annotators
  • Progress tracking — per-person progress and workload
  • Dataset export — export in formats ready for model training
