Improve Annotation Quality

Ango Hub by iMerit is built on quality-first principles to deliver precise annotations for training AI models. 

  • Workflow AssignmentAssign multiple annotators to the same asset in the workflow
  • Sample Labels for Training: Mark edge cases or good annotations as a sample for the annotation team
  • Quality Control: Reviewers can accept, reject, or fix someone else’s labels
  • Real-time TroubleshootingAnnotators can ask questions directly, which notifies project managers instantly
  • BenchmarkAdd benchmarks to tasks to measure performance and annotate again if needed
  • GuidelinesLabeling guidelines can be uploaded to the platform to align the annotation team.
