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.
One-click text redaction for images on your Mac
Apple's on-device machine learning model locates text regions in an image so you do not have to hunt for them manually.
Just click the detected box to cover the text, then save or copy the sanitized image.
Processing happens locally on your Mac; the developer declares that no data is collected from the app.
A menu bar item lets you choose an image to open or save a redacted copy without switching apps.
