Powerful open API

Our open source libraries for Python and Java provide API access to all the features of the Toloka data labeling platform.

  • Toloka-Kit is a Python library for working with Toloka via API. It allows you to build scalable and fully automated human-in-the-loop ML pipelines and integrate them into your processes.
  • Toloka-Java-SDK allows working with API functionality using JVM-based languages.

Tools for labeled data

Crowd-Kit is an open source Python library that simplifies working with crowdsourced data.

  • Aggregation methods for categorical, pairwise, textual, and segmentation responses
  • Metrics for evaluating uncertainty, consistency, and agreement with aggregate
  • Loaders for popular crowdsourced datasets

Pipeline management

Integrate your data labeling processes with popular workflow management platforms using our open-source Python libraries.

Build automated data processing workflows using ready-made tasks for frequent actions.

  • Trusted by leading ML&AI teams
  • "With Toloka we were able to resolve even the most difficult cases of recognizing handwritten text in documents for our customers."
    Founder and CTO of Dbrain, Y Combinator alum
    "Toloka is our source for a continual stream of data for large-scale projects. We collected the world's largest database of 200,000 unique photos and videos."
    Science Director and Co-founder
    "Thanks to Toloka, we're able to run numerous data projects on a regular basis. What we gain is a dependable approach to data labeling."
    Crowd Solutions Architect
    "Toloka is the first place we go to prepare data for Al. We get a full set of quality control tools and it's 10 times cheaper than our previous solution."
    Head of Technologies
    "We were really impressed with how fast we got our project done in Toloka - 10,000 ads were reviewed in just 12 hours."
    Special Projects Team
    “We use Toloka to prepare training data for speech technologies. It allows us to quickly test different markup methods and hypotheses and then choose the optimal approach.”
