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.”
