Frequently asked questions
Which AI-training platforms pay the most?
By median disclosed hourly rate among platforms with at least 50 open roles: AfterQuery Experts ($93/hr), Mercor Experts ($85/hr), Handshake AI ($83/hr). Full rankings by platform, domain, and task type are on the Pay Index page.
How is the median pay rate calculated?
From 717 distinct advertised rates across 29 platforms - deduplicated so a platform repeating one pay sentence across hundreds of listings can't vote hundreds of times, and drawn only from figures a listing actually states, never estimated. Full methodology is on the Pay Index page.
Does HumanSourcer charge providers or workers to be listed?
No. HumanSourcer is free to use, and no provider can pay to be listed, ranked, or to have a fact changed. Some outbound links may be referral links that earn a commission at no cost to you - none are currently live - and referral status never affects listing, classification, or ranking. Full policy is on the How We Make Money page.
Where does this data come from?
Every role listed is collected directly from a provider's own public application page or job board, not a third-party aggregator, refreshed daily. Every ownership and status claim on a provider profile links to its own public source.
