High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
Build, train, and deploy computer vision for the physical world
Label thousands of images in minutes using frontier models and custom filters, then curate datasets for training.
Combine detection, tracking, and logic blocks to orchestrate actions, update databases, and connect to industrial systems.
Run high-speed inference in the cloud or on edge devices, processing live video and images wherever the application lives.
Get into production quickly with an agent that sees the world, understands what is happening, and triggers actions.
