Earnings, Throughput, and Consistency: A Simple Model

Even experienced annotators benefit from a clear earnings model. On Rex.zone, consistency can unlock higher rates and more complex tasks.

Expected Weekly Earnings:

$E = r \times h \times c$

Where:

• r = hourly rate
• h = hours worked per week
• c = consistency factor (0.8–1.2), reflecting quality and reliability

Example: At r = $35, h = 20, and c = 1.1, you’d earn approximately $770 per week. Small improvements in consistency and throughput compound significantly over a month.

How to Start on Rex.zone in 5 Steps

Follow these steps to become a labeled expert and begin earning quickly.

1. Visit the portal: Rex.zone
2. Create your profile and enable Superhuman Profiles tracking
3. Complete onboarding tasks and quality checkpoints
4. Select task types (writing, evaluation, annotation) that suit your strengths
5. Schedule work blocks; start with shorter sessions to calibrate guidelines

Pro tip: Start with instruction-following and rubric-based evaluation to learn how tasks are graded.
Then expand into prompt writing and domain-specific labeling once you have confidence with edge cases.

Day-in-the-Life: A High-Quality Labeling Session

• 08:00–08:15: Review task guidelines and examples; note tricky edge cases
• 08:15–09:00: Complete a batch of text annotations; apply consistency checks
