Comparison
These are the seven worth your time. Pay figures are reported ranges for US/UK/Canada-based contributors as of mid-2026; individual offers vary and several platforms pay less outside those regions.
| Platform | Best for | Reported pay | The catch | |
|---|---|---|---|---|
| Mercor | Credentialed experts: MDs, JDs, PhDs, senior engineers, finance pros | $60–$250/hr | Hardest screen. A recorded AI interview is the gate, and matching to a project can take weeks. | Apply |
| Alignerr | Specialists who want a second queue; coding evaluators | $25–$200/hr | Headline rates are real but rare. Work availability comes and goes. | Apply |
| micro1 | Software engineers, especially with competitive-programming chops | $40–$120/hr | Engineering-focused; less for non-technical fields. | Apply |
| Outlier | Coding and writing tasks; broad global eligibility | $15–$60/hr | Queue instability is the common complaint. Pay is tiered by country. | Apply |
| DataAnnotation | Careful generalists and coders; lowest barrier to entry | $20–$60/hr | A 1–3 hour unpaid assessment with a low acceptance rate, and no retakes. | Apply |
| Handshake AI | PhDs, grad students, and credentialed experts | $50–$150/hr | Newer expert marketplace; project volume is still uneven. | Apply |
| Braintrust | Experts who want task-based work rather than waiting on a match | $20–$200/hr | AI training sits inside a general freelance marketplace, and the low end of the band is annotation work. | Apply |
Most contributors work two or three of these at once to smooth out the gaps between projects. Some Apply links are referral links; see the disclosure.
How it works
Every platform on this list runs roughly the same four steps. The details differ — the shape does not.
You upload a CV and pick the roles that match your background. Applying is free everywhere on this list, and you can apply to several roles and several platforms at once.
A recorded interview, usually 15–30 minutes, with an AI interviewer asking about your experience and one problem from your field. Some platforms use a written assessment instead. This is the real gate.
If you pass, they verify your credentials and identity, you sign a contractor agreement and confidentiality terms, and you set up payment. Then you wait to be matched to a project that needs your specialty.
You log hours against a project and get paid on the platform's cycle, usually weekly or bi-weekly, through Stripe, PayPal or Deel. Most projects cap your weekly hours.
Being accepted and having work are two different things — a wait between step 3 and step 4 is normal, which is why most people apply to more than one platform.
Safety
The seven platforms above are real companies that really pay. The problem is that scammers use their names. Someone messages you claiming to hire for Mercor or Outlier, and it looks convincing.
Here is how to tell the difference. If any one of these is true, it is a scam — walk away.
A real platform never charges you anything. Not to sign up, not for training, not for equipment, not for a background check. If you are asked to pay, or to deposit a cheque and send part of it back, it is a scam.
Only apply on the exact addresses listed below. Scammers register lookalikes with an extra word or a different ending, like "mercor-careers.com". Type the address yourself instead of clicking a link someone sent you.
You apply to these platforms — they do not come to you. If a recruiter messages you out of the blue on LinkedIn, WhatsApp or Telegram offering you a job you never applied for, it is not real.
Real interviews happen on the platform's own website. Nobody legitimate will interview you by text message on Telegram or Signal, and nobody legitimate hires you without any interview at all.

Before you apply
If you have a credential in medicine, law, finance, engineering or research, this is among the best-paid remote contract work available right now, and it is genuinely flexible.
If you do not, the generalist work is real and pays above most gig platforms, but the assessment is a genuine filter and the rates are a fraction of the headline numbers.
Nobody here is going to promise you placement, because nobody can.
FAQ
Grading a model's answers in your field, writing hard questions it should be able to answer, comparing two responses and picking the better one, or correcting mistakes. It is expert review work done through a web dashboard, not data entry.
For credentialed experts (MD, JD, PhD, senior engineer), Mercor's top rates are the highest in the market, with Alignerr and Handshake AI close behind on rare projects. For generalists, DataAnnotation and Outlier pay the most reliably.
No, but it matters. Mercor, Outlier, Alignerr and DataAnnotation all accept international contributors, though some listings are region-locked and Outlier tiers pay by country. Check eligibility before spending time on an assessment.
Yes. Most experienced contributors do, as long as it does not create a conflict of interest on a specific project.
Weekly to bi-weekly on approved work for most platforms. Mercor pays on a project cadence. All reputable platforms pay within about two weeks under normal circumstances.
Some of the Apply links are referral links. When someone signs up through one and gets hired, the platform pays a referral fee out of its own pocket. Your pay rate and your odds are identical either way, and the rankings are based on pay and reliability, not on which platforms have referral programs. Platforms without referral links are linked directly.
Who runs this
How I make money, stated plainly: other than my goal of helping people find this work, the referrals make me money. If you sign up through one of my links and get hired, the platform pays me a referral fee out of its own pocket. It does not come out of your pay, it does not change your rate, and it does not change your odds of being accepted.
The board is refreshed every day from the platforms' own public listings, so what you see is what they are advertising right now.
Only the essentials are shown here — title, pay, region and a link. Full job descriptions stay with the platform, and every role links straight back to the original posting.
Pay ranges, hire counts and regions appear exactly as the platform published them. Where a listing shows no rate, this site shows no rate rather than guessing one, and the date on the board is the real age of the data.
