This is the guide we wish had existed when we started. If you've heard about AI training work and want to understand it completely before deciding whether to try it — this is the full picture.
What Is AI Training Work?
AI training work is the process of providing human feedback that helps AI systems improve. When you use ChatGPT or Gemini and find it gives better answers now than it did a year ago, part of that improvement came from humans like you evaluating its outputs and indicating what was better or worse. You're paid to be one of those humans.
The specific tasks vary, but the core activities are:
- Preference rating — given two AI responses, which is better and why?
- Accuracy evaluation — is this AI response factually correct, appropriately detailed, and safe?
- Response writing — write a better version of this AI response
- Safety evaluation — does this AI output violate any safety guidelines?
What AI Training Work Is Not
- It is not passive income — you work and get paid; you stop working and income stops
- It is not a job — you are a freelancer/contractor with no employment status or benefits
- It is not a scam — the platforms are funded, legitimate companies with documented payment histories
- It is not only for tech experts — domain expertise of any kind (medicine, law, language, education) is valuable
What You Can Realistically Earn
| Your Background | Starting Rate | 10hrs/week (mo.) |
|---|---|---|
| No specific credentials | $16–$22/hr | €260–€360 |
| Degree / professional exp. | $22–$45/hr | €360–€730 |
| Specialist (law/med/eng) | $45–$130/hr | €730–€2,100 |
| Senior specialist (MD, JD, PhD) | $80–$200+/hr | €1,300–€3,200+ |
Which Platform Should You Start With?
If you have no prior experience: DataAnnotation.tech
DataAnnotation.tech has the most beginner-accessible onboarding. You take a skills assessment (1-3 hours), and if you pass, you can start tasks immediately. Most motivated beginners who read the guidelines fully pass on the first attempt. Pay starts at $16-22/hr for general tracks. Apply at: dataannotation.tech
If you have a professional background: Mercor
Mercor is the highest-paying and most broadly applicable platform. The onboarding is a 20-30 minute AI video interview where you describe your professional background. The more specific and credentialed your background, the better your matching outcomes. Pay ranges from $20/hr for generalists to $200+/hr for verified specialists. Apply at: t.mercor.com
Apply to both simultaneously
There's no reason to wait for one approval before starting the other. Both applications take under an hour total. Being approved on DataAnnotation.tech first while Mercor's matching processes gives you income faster than waiting for Mercor alone.
The single most valuable thing a beginner can do in week one is apply to multiple platforms simultaneously. The platforms don't compete with each other for your application — they're looking for different credentials and matching you to different projects. Applying to three platforms in one afternoon takes 2-3 hours and produces income 3x faster than applying to one at a time.
Step-by-Step: Your First Week
- Day 1: Apply to Mercor (AI interview) and DataAnnotation.tech (assessment) simultaneously
- Day 1-2: Set up a Wise account to receive USD payments
- Day 2-3: Complete DataAnnotation.tech assessment — read the full guidelines first
- Day 2-3: Complete Mercor AI interview — be specific about your credentials
- Day 3-7: Apply to Outlier AI (a third platform) for additional task coverage
- Week 2: Complete W-8BEN tax form for each platform that requests it
- Week 2-4: First tasks arrive; first payment follows within a week of completing tasks
Common Beginner Mistakes to Avoid
- Applying to one platform at a time — apply to 2-3 simultaneously
- Skimming the evaluation guidelines — read them fully; this is the most common cause of assessment failure and low quality scores
- Giving up during the approval wait — 2-4 weeks is normal; it doesn't mean rejection
- Not setting up Wise before your first payment — platform payment processes start when a balance is due; don't scramble to set it up then
- Working on only one platform long-term — task availability varies; 2-3 active platforms smooth the income curve
Tax and Legal Basics
AI training income is freelance income and must be declared. In Germany: register with the Finanzamt and declare in your Einkommensteuererklärung. In the UK: register for Self Assessment. Complete the W-8BEN form for US platforms — this prevents 30% US withholding tax. See our Germany tax guide or UK tax guide for the full framework.
