The category is real: Scale AI, Labelbox and Handshake all run one, and micro1 publishes peer-reviewed research on its own interviewer. That is exactly why the imitations work. Here is what a genuine platform does, the things that feel wrong but are normal, and the signals that mean stop, drawn from what the five platforms on this board actually publish.
Every listing on this board advertises an hourly rate, and almost none of them pay by the hour. What you are really agreeing to is a per-task rate, a payout schedule, and a payment rail that has to reach your country. Here is what each platform publishes about all three, and the gap between the number in the ad and the number in your account.
Every platform runs the same five steps in a different order: profile, eligibility, assessment, onboarding, then a wait. Most people do them backwards and burn an evening on an unpaid AI interview for a project their country was never open to. Here is the sequence that fails fast and cheap, with what each of the five platforms actually asks for.
"AI training" covers three different jobs: labeling data, judging what a model produced, and doing your own professional work so a model can learn from it. They pay differently, screen differently, and want different people. Here is what separates them, and which one the listings on this board are actually offering.
Country eligibility is decided at two gates: whether the platform can engage you at all, and whether the specific project is open where you live. Of the five platforms we track, two publish a policy you can check in advance, and only one tells you, on the listing itself, which country a given project is open in. This guide sets out what each actually says.
Every listing shows its pay and who it is open to.
