A plain-English look at the tasks behind AI training and data annotation jobs, and what the listings do not promise.
People search for “data annotation jobs” and “AI training jobs” as if they were one thing. In the listings we read, the work is usually closer to careful reviewing than to factory-style tagging, especially at the higher advertised rates.
On a generalist Mercor pool, the posting describes writing prompts, grading whether an answer is correct and on-instruction, and catching confident mistakes. On Outlier’s English media track, you might compare AI images or videos, talk to a voice model, or correct captions. Language roles can mean fixing transcripts into British spelling, or judging whether a model sounds like UK English. Specialist science, law and finance roles ask you to use training you already have, often to write a rubric or to say why one model answer is better than another.
Platforms pay for judgment they can defend. If your explanations are vague, or you rush, work can dry up even after you have passed an exam. That is a common pattern in public discussions of this work, and it is why we do not promise earnings.
If a role involves voice recording, read the posting on consent and cloning before you apply. The UK English voice listing we read is explicit that your voice may be cloned for a customer-experience agent.
