What’s behind our guaranteed results

Toloka offers a diverse set of ready-to-use tools for data labeling to get your project off the ground in record time. Our solutions incorporate advanced quality control methods and aggregation tools, autolabeling and verification, and a curated crowd of performers — all supported by our high-performing infrastructure for reliable fault tolerance and security.


Multifaceted quality control

When it comes to quality control, there is no silver bullet — which is why Toloka uses different
combinations of approaches to achieve the best quality for each project:

  • Crowd filters (language, interests, real-time ranking, and more)
  • Manual quality checks, spot checking
  • Task-based crowd training and testing
  • Automated quality checks (majority vote, excluding fast responses and robots, and more)

Intelligent crowd technologies

  • Diverse global crowd

    Millions of performers across every time zone for non-stop labeling and instant scaling, with support for 40+ languages. Verified performers are also available for extra-sensitive data.

  • Smart performer ranking

    Performers are matched to tasks with personalized rankings based on their interests, skills, and history of performance in similar tasks for optimal speed and quality.

  • Adaptive performer selection

    The best performers are automatically selected in real-time using personalized quality forecasts that can predict individual performance on a specific task.


Autolabeling & verification

Automated prelabeling is available to increase throughput and eliminate random errors with continuous training. Results are verified by human performers for guaranteed quality. Contact us if you are interested.
