AI training work pays people to improve machine-learning models: rating model responses, labeling images, writing and evaluating prompts, transcribing audio, and reviewing code. Demand has exploded, and so has the spread between the best and worst platforms — generalist microtasks pay a few dollars an hour while expert-domain projects (law, medicine, advanced coding) pay $15–40+/hr, sometimes on the same platform.
Every AI-training platform we list goes through the same verification discipline as every other category: pay models, qualification gates, identity requirements, payout methods, and country availability, checked against official contributor pages and terms. Where a platform hides its rates, we say so.
Before you apply, understand the two-tier structure. Generalist tiers accept most applicants and pay per task; expert tiers gate entry behind degree verification and domain tests but pay multiples more. The application-process row on each platform page tells you which you are walking into.
