AI marketplaces and tools expand low-barrier side work

Mercor, Outlier, and DataAnnotation illustrate growing demand for AI-training labor, but advertised hourly rates may overstate effective earnings because of screening, idle time, task scarcity, and rejected work. Broader opportunities include AI receptionist setup, workflow automation, short-form clipping, UGC, tiny apps, digital products, and AI-assisted Etsy advertising; verified income evidence remains limited.
