If you’re looking for a flexible way to earn extra money, whether you’re traveling, living abroad in Spain, or just want work you can do from anywhere, Mercor is worth a look. It’s not your typical freelance marketplace, and that’s exactly why it stands out.
What is Mercor?
Mercor is a platform that connects professionals with remote, contract-based work, mostly projects tied to AI training and evaluation. Think of it as a middleman between you and companies that need human expertise to build and improve AI systems. Doctors, lawyers, engineers, financial analysts, translators, writers, and plenty of other professionals all use it. The pitch is simple: you apply once, and Mercor matches you to projects that fit your background. No endless bidding against the lowest price like on some other freelance sites.
How it works
Getting started takes three steps:
1. Create a profile — sign up and build a professional profile with your skills and experience.
2. Take AI assessments — these help Mercor figure out what you’re good at and match you to relevant work.
3. Find opportunities — offers start coming in based on your qualifications.
The work is genuinely project-based. Some gigs are short-term and one-off; others stretch into longer-term engagements. That flexibility is the whole appeal: you pick up work when you need it, and step back when you don’t.
Why people like it for extra income
- Fully remote — work from anywhere, on your own schedule. Perfect if you’re in Spain for a few months or just prefer not to commute.
- Competitive pay — hourly rates vary by role, but many listings sit in the $50–$150/hour range, with some specialized roles going higher. You’re paid weekly.
- No cold pitching — instead of chasing clients, you get matched to roles that fit your profile.
- Flexible commitment — because it’s contract work, you control how much or how little you take on.
A few honest comments
Mercor’s focus is heavily on AI-related work, so it’s not a general-purpose freelancing site like Upwork or Fiverr. If you have professional expertise in a field (finance, law, healthcare, engineering, coding, writing), you’ll find more opportunities than a generalist would. And like any freelance platform, the work isn’t guaranteed; you still apply and get matched, rather than being handed projects automatically.
If you want a low-friction way to earn extra money remotely, whether you’re between jobs, traveling through Spain, or just want side income, Mercor is a solid option. You apply once, get matched to project-based work, and get paid weekly for contributions that actually help shape AI. It’s worth setting up a profile and seeing what offers come your way.
I know it feels a little backwards to promote AI work when I care about keeping things green and human-centered. But here’s how I see it: the work on Mercor isn’t about replacing people; it’s about making AI more accurate and less harmful. When you contribute, you’re helping catch errors and teach models to be more careful, which means less wasted compute and fewer bad outputs downstream. That’s efficiency work, and efficiency is a form of sustainability. You’re not out to take anyone’s job; you’re helping build AI that gets it right the first time.
