AI Training Jobs in Brazil: Portuguese Roles and Pay

Can I do AI training work from Brazil, and which programs list it?

We take people from every country. Tell us what you do and we'll send you what's open to you.

Yes, and Brazil has more country-specific listings than most countries we checked. Mercor, Outlier and Prolific publish country lists that include Brazil; Mindrift and micro1 publish only the places they cannot serve, and Brazil is not among them. The table lists every program we checked on 14 November 2026, alphabetically.

"Up to" figures are ceilings. Per-task and per-video rates depend on accepted work.

Work for PhDs and subject experts in Brazil

RWS is building a Brazilian Portuguese benchmark of hard, real-world questions and recruits subject experts by city. Its History listing pays "Rate: 30 USD/hour" and requires a "PhD in a relevant field (required)"; Arts pays 26.40 USD and Food, Drink & Culinary Culture 21.60 USD. The listings also say "Use of AI tools to generate answers or questions is strictly prohibited." (History; Arts; Food).

Alignerr's physics listing is located in São Paulo at $35-55 an hour (Alignerr listing), Handshake AI recruits STEM PhDs residing in Latin America at up to $30 an hour (Handshake AI), and Turing's Technical Content Writer listing names Brazil (Turing). Turing's LATAM coding listings pay "$25 per approved task" (Turing LATAM).

If you hold a degree or licence in medicine, law, engineering or a science, tell us what you do and we'll send you the paid AI work that fits. See also AI training jobs for PhDs.

Recording, maps and one-off studies

micro1's At-Home Video Recorder (LATAM) pays $6 an hour of accepted first-person video of household chores and names Brazil and Mexico among its countries. It requires an iPhone 12 or later, a Google Pixel 6 to 9 or a Samsung Galaxy S21 or later (micro1 listing). OneForma's Local Maps Search Evaluator and Paragraph-Level Translation Quality Rater both list Brazil (maps; paragraph rater).

Mercor also ran a one-off Brazil Personal & Cross-Border Finance study: "$100 / one-time Contract Remote (Brazil)" for a 20-minute survey, aimed at people with financial ties to the US (Mercor listing). For more capture work, see AI voice and data jobs.

Getting paid in Brazil: Wise, PayPal and Deel

Mercor's payment page says "Payouts use Stripe Connect" except for countries marked Wise, which "are paid through Wise instead"; Brazil carries the Wise marker (Mercor payments). Outlier pays via PayPal, Airtm or ACH, micro1 in USD twice a month through Deel, RWS by PayPal or bank account, Prolific by PayPal, and Turing to a bank account.

We did not read each payment provider's own Brazil pages, so check conversion fees and how money reaches your Brazilian account before your first payout. See AI training payment methods.

Tax on AI training income in Brazil: the carnê-leão

Receita Federal says: "Carnê-leão é o imposto sobre a renda mensal de pessoa física residente no Brasil recebida de outra pessoa física ou do exterior." In English, it is the monthly income tax on money a Brazil resident receives from another individual or from abroad, and it must be paid by the last business day of the month after you receive the income (Receita Federal). Its list of income subject to the carnê-leão starts with "Trabalho sem vínculo empregatício", work without an employment relationship, from a source abroad (Receita Federal).

Whether you should instead invoice through a company is a question for a contador. For US forms the programs may ask for, see taxes on AI training income. This is general information, not tax advice.
