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.
Only your face unlocks your Chrome browser
Instead of verifying you once at sign-in, SETI Protect keeps checking the face at the keyboard for the whole session.
Because authentication continues after login, a passerby who takes over an unlocked, already-signed-in browser is detected rather than trusted.
The extension is positioned to stop remote desktop takeovers, a common route for attackers into an authenticated browser.
Built by Smart Eye Technology, whose framework layers facial recognition with fingerprint, handwriting and voice verification as biometric MFA/2FA.
