Microtask crowd · Gamified labeling contests
DiagnosUs
DiagnosUs, built by Boston-based Centaur Labs, turns medical image, ECG, and clinical-text labeling into daily accuracy contests that a global crowd of medical students, nurses, and physicians competes in for cash prizes paid via PayPal. It is actively maintained (App Store version updated August 2026, 4.8 stars) and open worldwide, though prizes are small and performance-based rather than a fixed hourly or per-label rate. A referral program exists, but its terms restrict links to personal, non-commercial use with a roughly $20 lifetime referrer cap, so it is not a link a public directory can publish.

Pay is performance-based contest prizes, not an hourly or per-label rate, and the platform does not publish a rate. Worker reports put realistic earnings in the coffee-money range: a personal-finance blog and several App Store reviewers describe up to about $50 in a strong day and PayPal cashouts of roughly $40 to $140, with a few power users citing $200 in a good week. Payout is via PayPal once a withdrawal minimum is met. Prizes are funded by the AI and research customers whose medical datasets are being labeled.
