Centient
Earn USDC on Stellar for ranking AI responses — instant micro-payments, no bank account, no minimum payout. High-quality human preference data, accessible worldwide.
AI companies need cheap, high-quality human preference data to train and evaluate their models, but most labeling platforms exclude the developing world through banking requirements, high minimums, and slow payout rails — while paying workers a pittance and keeping most of the margin.
The solution
Centient is a web app that connects to a Stellar wallet (Freighter): a user compares two AI-generated responses to a prompt, picks the better one with a one-line justification, and is paid instantly in USDC on Stellar — settling in about five seconds for a fraction of a cent in network fees, with no bank account and no minimum payout threshold. Labelers can bank their work into a balance and withdraw in a single lump sum whenever they’re ready.
Built on Stellar
Stellar’s near-zero fees and ~5-second finality make it a natural fit for many small cross-border payments, and its anchor network (regulated on/off-ramps plus native USDC) gives labelers a direct path from earnings to local currency across Sub-Saharan Africa, Southeast Asia, and Latin America.
