Every time you use an AI chatbot and get a convincing answer, there is often a person behind it who has read, compared and corrected thousands upon thousands of wrong responses. These workers are called AI trainers, and in recent years they have become one of the most in-demand roles in the global economy.

Much of that has to do with pay. Some talk about earnings in the triple digits per hour, others about a few tens of euros a month. It depends heavily on skills, the platforms you work for and the type of contract.

If you are curious about the profession, this guide covers what an AI trainer is and does, how much they can earn, the types of contracts on offer and the protections available.

What an AI trainer does

Although the job is closely tied to technology, its core is human feedback. You converse with an assigned AI model, evaluate its answers, correct any inaccuracies and then rank responses for usefulness and coherence, in a process known as RLHF (reinforcement learning from human feedback).

In practice, the trainer writes a prompt and then judges the responses received. On projects in Italian, duties also include translating content, reviewing quality and adapting idioms and regional variants. No coding is required; careful reading and precise writing are enough.

What is the official job title? On April 30, 2026, UNI (Italy’s national standards body) published standard UNI 11621-8, the first national standard in Europe on professional profiles in AI.

It covers 12 profiles in total, including data scientist and machine learning engineer, but “AI trainer” does not appear among them. The standard is voluntary, so the title has no agreed boundaries and very different tasks sit under the same label.

What skills you need

The main requirement is a degree. For positions in Italian, employers usually ask for a university degree, even a three-year one, and good English. Master’s degrees, experience in writing, translation or content evaluation, and knowledge of several languages count in your favor.

Analytical precision, critical thinking and command of language also matter. In general, the more specific the expertise, the higher the pay. Law and finance start at higher rates than generalist tasks.

How to become an AI trainer

AI professions are not regulated: there is no professional register and no state exam. To get in, you go through the platforms themselves. Typically you first fill in your profile with experience, languages and area of specialization, then pass a practical test to demonstrate your skills, and finally gain access to available projects.

Because most of these jobs are freelance, you decide how much and when to work. Other companies prefer a more direct approach, with video interviews conducted by AI that can be repeated.

How much AI trainers earn

The market for AI trainers is unusual and is structured in tiers. As noted, much depends on the type of company, the contract, the chatbot in use and the tasks performed. At the end of 2025, for example, DataAnnotation started at $20 an hour for generalists and $40 for projects tied to law, medicine or finance.

Outlier, by contrast, offered $15 to generalists and $30 to $50 to a physics expert. Mercor started at $130 to $170 an hour for general practitioners, down to $110 to $130 for lawyers, plus salaries of $90,000 to $200,000 a year for full-time tutors.

Freelance projects typically lasted three to four weeks, at 10 to 30 hours a week. The average works out to about $85 an hour.

The situation in Italy

In Italy, the situation is similar to the rest of the world. DataAnnotation’s Italian page cites pay from €45 an hour (about $49) for bilingual translators and reviewers, weekly payments and no minimum hours. A degree, even a three-year one, and good English are required. The description also mentions rates of €20 an hour (about $22), so the rate depends on experience and project.

It is not all as positive as it may seem. The picture is often one of intermittent micro-assignments, invoices still to be issued and earnings as low as €100 a month (about $108). For company employees, the data are even more fragmented. Estimates for a junior role run between €28,000 and €35,000 gross a year (about $30,200 to $37,800).

AI skills in Italian job listings grew 93% in a year. In 2026, AI adoption among Italian businesses stands at 22%, against 32% for the European average. The domestic market therefore still absorbs little, and clients are mostly foreign.

VAT number and taxes

Since these are mostly freelance roles, you almost always need an Italian partita IVA (VAT registration) to start working. The regime forfettario (Italy’s flat-tax regime for small businesses) has a revenue ceiling of €85,000 (about $91,800) and a 15% substitute tax, reduced to 5% for the first five years of a new business if certain requirements are met.

Above €100,000 (about $108,000) in revenue, you exit the regime immediately. Before even opening one, we recommend asking an accountant for the correct ATECO code (Italy’s business activity classification) and the INPS (Italy’s national social security institute) contributions to be paid.

The bottom rung of earnings

In 2023, Time published an investigation that revealed a very different picture of AI trainers. Employees of Sama in Kenya filtered violent content for OpenAI with take-home pay between $1.32 and $2 an hour. Sama replied that earnings ranged from $1.46 to $3.74 an hour after taxes.

The workers interviewed also said the work had left them psychologically scarred, and Sama ended the contracts. There is also a lawsuit against Scale AI involving Outlier trainers, who said they wrote prompts about violence and abuse without adequate psychological support.

What to check before applying

Before you apply, read the contract carefully. Many platforms engage trainers as independent contractors, without the protections of employment.

Something could change: by December 2, 2026, Italy must transpose the European directive on platform work. It is not yet clear whether it will cover this sector.

Also pay attention to entry tests, to find out whether they are paid and how long they take. Finally, read the privacy policy before uploading identity documents or bank details because, in this sector too, scams are not uncommon.
