What this actually is
You bring your specialist expertise to AI evaluation. The shape of the work varies but the pattern is the same: review outputs, rate quality, write prompts, flag errors. The platform title (Cybersecurity Experts) reflects the rate band and the expertise required, not the day-to-day work.
