All-in-one content moderation API for images and video
Screen photos, videos and live streams for unwanted content through a single automated API.
Detect nudity, weapons, alcohol, narcotics, offensive gestures and hate symbols without building your own models.
Extract text from images, verify PPE compliance (face, hand and head covers) and run real-time facial similarity matching.
Minimal-code integration with ready-made SDKs and documentation so teams can ship quickly.
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.
