Where the work is
Where certified AI workers apply
These are the platforms that hire AI data workers. Each one runs its own application, its own unpaid qualification task and its own quality bar. A Certalyx certificate does not shortcut that process — it gives you evidence of assessed competency to bring to it.

Generalist and specialist AI training work. Paid per task, application plus assessments.
Alignerr

Mercor
Matches specialists to AI labs. Interview-led, often higher rates.

Before you apply anywhere
- No legitimate platform charges you a fee to be onboarded or to access tasks.
- Read the qualification guidelines properly. Most rejections are edge cases, not speed.
- Keep a record of every completed batch, quality score and certificate you earn.
