Behind the rate
How do AI trainers get paid? What sets each platform's rate
Updated
A published rate answers only part of the question. Several platforms' pages also say what kind of work each of their figures is for, and that decides where in a range a trainer lands.
The field sets the band
Alignerr's home page prices English writing at $30-40/hr and finance work at $55-110/hr. DataAnnotation lists Japanese specialist language work at $25 to $40 an hour and software engineering coding at $40 to $150+, so one platform lists very different rates depending on the work you can do.
Prolific's floor, and seeing the rate before a task
Prolific's payment principles set a minimum of £6 / $8 per hour for the studies on it. Mindrift's home page says compensation is always visible before you begin each task, so the rate can be checked before any work is done.
What the board has yet to record
The pay board answers how pay is set and the published range. It has not yet captured each platform's payout method or payday, so read those on the platform's own help pages before you start.
