OpenTrain AI is a hiring platform built specifically for AI training work: data labeling, annotation, RLHF, fine-tuning, and other tasks that go into building reliable AI systems. If you need people to label your data, annotate your datasets, or train your models, you post a job. If you do that kind of work, you build a profile and apply.

​
Who it’s for

Employers are companies and teams that need AI training talent. You post jobs, review candidates, run AI-powered screening, and pay your hired AI trainers through the platform. AI trainers (data labelers) are the people who do the work. You set up your profile, upload your resume, and apply to jobs that match your skills — whether you work independently or as part of an agency.

​
How it works

  1. Sign up at app.opentrain.ai and choose your account type.
  2. Set up your account — employers complete a short profile; AI trainers go through a multi-step onboarding wizard that captures your experience, skills, education, and hourly rate.
  3. Post or apply — employers publish job listings and receive candidate proposals; AI trainers browse matched jobs and submit applications.
  4. Work and get paid — communicate through the built-in messaging system, track work via milestones, and receive payment to your connected bank account.

​
Key features

  • AI-powered job matching — the platform surfaces the most relevant candidates for each job based on skills, experience, and language capabilities.
  • Resume autofill — AI trainers upload a resume and the platform auto-populates their profile fields, reducing manual data entry.
  • Structured AI screening — employers configure interview questions; candidates answer them before submitting proposals, giving you structured data to review.
  • Agency onboarding — teams of AI trainers can onboard as an agency, with company-level profiles covering headcount, security credentials, and pricing.
  • Milestone-based payments — employers pay through milestones; AI trainers add a payout method through OpenTrain and receive payouts in supported payout countries.
  • Integrated messaging — proposal messages and job-channel conversations keep all communication in one place.
