If you have spent any time in foreign-resident Facebook groups in Korea recently, you have probably seen the Alignerr posts: "Get paid $80-$120/hr to train AI. No experience required. Fully remote." The replies are split. Some people say they pulled in two thousand dollars in a month. Others say the platform is a scam, that the work dried up after a week, that the projects close as fast as they open.
Both are true. Alignerr is real and it pays, and the experience varies wildly by category, by region, and by what kind of expertise you bring. This guide unpacks what Alignerr actually is, what the work looks like day-to-day, what the rates really are once you account for project availability, and how Korean visa and tax rules apply to USD remote contract income.
The Trustpilot 4.6 vs Glassdoor 2.2 divergence
The headline numbers look contradictory. Trustpilot rates Alignerr 4.6 out of 5 across over 2,300 reviews. Glassdoor rates Alignerr 2.2 out of 5 across 23 reviews, with only 23% of reviewers recommending the company to a friend.
Both data sets are real. The divergence is structural, not contradictory:
- Trustpilot measures customer experience. For Alignerr, "customers" means contributors who applied, got onboarded, did some work, and got paid. The bar is low and the moment of feedback is early. Most reviewers are commenting on the application and onboarding flow, which Alignerr designed well.
- Glassdoor measures the long-term employee or contractor relationship. The 23-review sample is small, but the people who write Glassdoor reviews tend to be those who put in serious time, hit project-availability droughts, dealt with project closures, or felt the rate band did not match the actual work. They self-select into the lower end of the satisfaction curve.
The honest read: Alignerr is a real platform that pays real money. It is also a freelance platform with no guarantee of work. The first month is good; sustainability is uncertain. The same shape is true of Outlier, Mercor, DataAnnotation, and every other AI training platform.
What Alignerr is and who runs it
Alignerr is owned and operated by Labelbox, a San Francisco AI data company. The Alignerr homepage explicitly carries the "Powered by Labelbox" attribution. Labelbox has been in the AI training data business since 2018 and has raised over $189 million in venture funding through 2024, including investments from Andreessen Horowitz and Snowpoint Ventures.
This matters because the underlying company is well-funded and well-known. Payment risk on Alignerr is low compared with smaller AI training platforms. If you do the work, you almost certainly get paid. The risk that does exist sits elsewhere: in whether projects in your category remain open long enough for you to earn a meaningful amount.
The r/alignerr subreddit has roughly 25,000 members and is the closest thing to a community ground-truth. Worth reading before you commit serious time.
What the work actually is
This is where most prospective applicants get the wrong picture. Alignerr lists roles with titles like "Senior Software Engineer - Agentic Coding ($80-$120/hr)" or "Mathematician (Foundations / Formalization) ($170-$200/hr)." The titles describe the rate band and the expertise the platform wants you to bring. They do not describe the work.
The actual day-to-day work on Alignerr is:
- Reviewing AI-generated outputs in your area of expertise.
- Ranking which of two model responses is better, and writing a short rationale.
- Writing test prompts designed to stump current models.
- Flagging errors in AI outputs and rewriting them.
- Recording voice samples or transcribing audio (for audio roles).
- Operating a phone or video setup to record everyday tasks (for robotics roles).
You are being paid for your expertise as input data, not to ship software, deliver translations, or do original research in the traditional sense. The "Senior Software Engineer" hourly rate of $80-$120 is real, but the work is fundamentally evaluation, not engineering. People who join expecting "engineering work" usually churn within the first week.
This honest framing is not in Alignerr's marketing copy and is rarely in the YouTube reviews. It is the single biggest reason people leave bad Glassdoor reviews. Knowing it up front fixes most of the disappointment.
Pay reality: rates by category, and the Korean-vs-Filipino gap
Alignerr's public roles page lists 458 distinct active roles across six categories. The rate distribution is wider than the marketing suggests:
| Category | Roles | Typical pay |
|---|---|---|
| STEM and research | 148 | $40-$400/hr |
| Coding | 104 | $40-$120/hr |
| Voice and audio | 76 | $40-$280/hr |
| General | 57 | $20-$120/hr |
| Language | 43 | $10-$120/hr |
| Other (finance, specialist) | 30 | $40-$150/hr |
The top-paying roles cluster in two places: voice acting in less-represented European languages (German Generalist Voice Actor: $250-$280/hr) and frontier ML evaluation work (Machine Learning Evaluation Specialist: $200-$400/hr). These are also the smallest categories by hours actually available.
For Seoulstart's audience specifically, the language-pair rates are the most relevant, and they tell a clear story:
| Language | Pay band | Why |
|---|---|---|
| Vietnamese Language Expert | $40-$120/hr | Smaller qualified-bilingual pool, higher rate |
| Tagalog Language Expert | $40-$120/hr | Same |
| Filipino Language Expert | $40-$120/hr | Same |
| Chinese AI Language Expert | $25-$30/hr | Large global pool of qualified speakers |
| Korean Language Expert | $20-$40/hr | Same |
| Korean Audio Transcription | $10-$15/hr | Most-saturated category |
The 3x gap between Vietnamese or Tagalog and Korean is not a slight. It is supply and demand. There are far more qualified bilingual Korean speakers in the global remote contractor pool than there are qualified bilingual Tagalog or Vietnamese speakers. If you are a native Filipino or Vietnamese speaker in Korea reading this, the Alignerr Filipino or Vietnamese Language Expert role is one of the highest-leverage remote income sources we have seen for your community.
If you are Korean or Korean-heritage, the language rates are mediocre but the STEM and coding rates are excellent. Pick the category that matches your expertise, not the one that matches your passport.
Can you legally do this on your Korean visa?
This is the part of the conversation that Alignerr (and every other AI training platform) does not have, because it varies by country. In Korea, it varies by visa class:
- F-2, F-4, F-5, F-6 (open work rights): You can take Alignerr work freely. No permission needed.
- E-1 through E-7 (employment-based visas): You are bound to your sponsoring employer. Concurrent employment requires a permit from Immigration and consent from your employer. Remote contract work for a foreign company paid in USD to a foreign account is a genuine grey area. The cautious read is that it counts as concurrent employment under Korean immigration law; the permissive read is that work performed for a non-Korean entity is outside the Korean immigration framework entirely. Until HiKorea clarifies in writing for your specific case, the cautious read is safer.
- D-2, D-4 (student visas): You need a 체류자격외 활동허가 (activity-outside-status permit). The weekly hour cap is tiered by your TOPIK level (roughly 10 to 35 hours), not a flat 20. Same grey area as above for remote foreign-company work, and the tiered hour cap is the binding constraint for most students. Confirm your limit on HiKorea or by calling 1345.
- D-10 (job seeker), D-8 (business): Case by case. D-10 holders generally have more latitude. D-8 holders are tied to their registered business activity.
If you are unsure, the safe path is to call the 1345 Immigration Contact Center (English available) and describe the work specifically: "I am paid in USD by a US company for remote work that I perform from Korea, paid into a foreign bank account." The answer you get is the answer that protects your visa.
Korean tax: the 5-year exemption that almost nobody knows about
This is where the conversation becomes useful for most foreign residents.
Korea's Income Tax Act (소득세법) distinguishes between two types of tax residents:
- Permanent residents: people who have had a domicile or residence in Korea for more than 5 years during the past 10 years. Taxed on worldwide income.
- Non-permanent residents: people who have had a domicile or residence in Korea for 5 years or less during the past 10 years. Taxed on Korea-source income in full, but on foreign-source income only to the extent that it is paid in Korea or remitted into Korea.
For most foreign residents in their first 5 years in Korea, this is huge. USD paid by Alignerr (a foreign company) into a foreign bank account is foreign-source income. If you do not remit it into Korea, it is not taxed in Korea during the exemption window.
The practical implication: open a foreign-currency account that you can access from Korea but that holds the funds outside of Korean banks (Wise, for example, holds your USD balance in the US until you choose to convert). Keep your Alignerr earnings there during the first 5 years. Convert and remit only what you need to live on.
After year 5, the exemption ends and worldwide income is taxable. Two things to know about that transition: the 5-year clock is based on cumulative residence in the past 10 years (not a single continuous period), and Korea has tax treaties with the US, UK, Vietnam, the Philippines, China, and Russia that typically allow foreign tax paid to be credited against Korean tax owed on the same income.
Talk to a Korean tax accountant before year 5. The interaction between the exemption end, the treaty credit, and your specific country of origin is the kind of detail that benefits from a $200 consultation.
Should you sign up?
If you are a foreign resident in Korea with an open work visa (F-2, F-4, F-5, F-6) and any of:
- Native Vietnamese, Tagalog, or Filipino fluency
- Senior coding or software engineering experience (and a tolerance for evaluation work)
- A STEM PhD or advanced research expertise
- Professional voice acting credentials, especially in less-represented European languages
...the platform is worth the application time. Realistic expectation: $500 to $2,500 in the first month of active work, dropping or rising depending on project availability in your category.
If you are on an E-visa or D-visa, resolve the visa question with Immigration first. The income is not worth the visa risk.
If you are in your first 5 years of Korean residence, set up a foreign-currency account before you start. The 5-year exemption is the single biggest financial lever in this guide.

FAQ
Is Alignerr legit?
Yes. Alignerr is owned by Labelbox, a well-funded San Francisco AI data company. People who do the work get paid. The legitimacy question is not "will I get scammed" (you will not), but "will there be enough work in my category to make this worth my time" (answer: depends on category).
How much do Alignerr jobs actually pay?
Advertised rates are maximums, and actual earnings depend heavily on project availability. The platform's documented top rates cluster around $150/hr for specialist roles; treat anything advertised well above that with skepticism and verify on Alignerr's current listings. Language roles pay much less, with Korean roles at the lower end. Realistic first-month earnings for an active contributor are a few hundred to a couple thousand dollars, not the headline hourly rate multiplied by a full work week.
How does Alignerr pay contributors?
According to Alignerr's published FAQ, contributors are paid weekly via direct deposit. Community reports on r/alignerr cite PayPal, Payoneer, and ACH as available payout methods. For workers in Korea, PayPal or Payoneer (both accept USD into a foreign-held balance) are usually the cleanest options.
Can I do Alignerr work on a Korean E-visa?
Not without a concurrent-employment permit from Immigration. Remote contract work for a foreign company paid in USD is a genuine legal grey area in Korea, but the cautious read is that it counts as concurrent employment under the Immigration Control Act. Call 1345 and describe your specific case before you start.
Do I owe Korean tax on USD income from Alignerr?
If you have been a Korean resident for 5 years or less in the past 10 years, you are a "non-permanent resident" under the Korean Income Tax Act. Foreign-source income is only taxed in Korea to the extent it is remitted into Korea during this period. If you keep your Alignerr earnings in a foreign bank account, you generally owe no Korean tax on them in your first 5 years. After year 5, you are taxed on worldwide income.
What is the catch?
Project availability. You can sign up, get onboarded, do five hours of work in the first week, and then find that no projects in your category open for the next month. The platform pays well per hour, but it does not guarantee hours. Treat it as a supplemental income source, not a primary one, until you have seen your category's availability over three months.
