A selective community of experts

Work alongside writers, lawyers, health professionals, coders, professors, and bilingual experts shaping the future of AI.

The problems here actually require engineering judgment. It's some of the most rigorous work I've done outside of a staff role.

Marcus

Software Engineer

The variety is what I didn't expect. One week I'm rewriting technical explanations, the next I'm evaluating how a model handles tone and voice.

Julia

Senior Copywriter

Clinical nuance matters in this work. It's rare to find contract work where my specialty actually gets used properly.

Melissa

Clinical Reviewer

The evaluation work here is more rigorous than most PM research I've run in-house. I've genuinely changed how I think about product quality.

Azhar

Senior Product Manager

Legal reasoning in AI is still an unsolved problem. Getting to shape how these models handle it, from a practitioner's perspective, is the work I actually want to be doing.

Krysta

Solicitor

The code review standards here are higher than most teams I've worked on. It's sharpened how I think about edge cases in my day job.

Tyler

Senior Engineer

Pressure-testing these tools surfaces failure modes that matter. The work holds up to the standards I'd apply in practice.

Abi

Litigation Attorney

Most freelance work in my field is content mills. This is the first engagement where my clinical training is the reason I was hired, not an afterthought.

Liana

Clinical Researcher

My writing background is exactly what this work needs. Evaluating how models handle narrative, voice, and subtext is surprisingly rigorous.

Mi Ji

Screenwriter

What you'll actually be doing

No machine learning background. No programming skills. No AI research experience. What we need is what you already have — deep knowledge in your field, sharp analytical judgment, and the ability to tell when something is wrong and explain why.

01

The role

You teach. AI learns.

You're not coding algorithms or training neural networks. You're reading an AI's attempt at a complex problem — a legal brief, achemistry proof, a financial model — and telling it exactly where and why it went wrong.

Your domain expertise IS the training data. Every correction, every rewrite, every quality judgment you make teaches the next generation of AI to reason more like an expert.

02

The challenge

The work is genuinely engaging.

These aren't checkbox surveys or multiple-choice quizzes. You'll evaluate whether a model correctly derived a DCF valuation, catch a hallucinated case citation, or identify a flawed reaction mechanism. The kind of problems that use what you actually know.

That's what makes it interesting, and what makes your contribution irreplaceable. AI can generate plausible text. Only a domain expert can tell when it's subtly, dangerously wrong.

03

The impact

One review. Millions reached.

Every annotation you write becomes a permanent part of how AI systems reason. When you correct a misapplied accounting standard or a flawed physics derivation, that correction propagates to millions of future interactions.

This isn't hypothetical impact. The models you train are deployed at scale, used by researchers, professionals, and students worldwide. Your expertise echoes far beyond a single task.

"The pay is genuinely competitive with engineering contract rates, which surprised me. I pick up hours when I want them and leave it alone when I don't."

Ben

Software Engineer

"The rates are well above what I'd earn on most Tokyo contracts. It covers what I need so I can actually spend time on my own creative work."

Nanase

Professional Translator

"Setting my own hours sounds generic until you've spent years not being able to. The writing work itself is also more interesting than I expected."

Salime

Creative Writer

"I have two young kids. Logging on after bedtime and still earning meaningfully is the part that matters. Teaching didn't give me that option."

Anthony

Educator

"The project variety is the thing I didn't expect. Different task types, different skill demands. Keeps it from feeling like a second job."

Shannon

Product Designer

"Medicine doesn't usually allow for remote or flexible work. Having something that pays well and fits around clinical hours has made a real difference."

Omar

Physician

"I'm a Costa Rican living in France, so fully remote isn't optional for me. The pay being better than my previous role was the unexpected part."

Alejandro

Data Analyst

"Straightforward to pick up, decent rates, no meetings. That's most of what I need from a side income."

Sean

Data Scientist

"I've taken calls from trailheads and answered tasks from a hammock. The work gets done, the pay shows up, and nobody cares where I am."

Austin

Biomedical Engineer

"It's one of the few remote gigs where the math I actually teach is relevant. I fit it in between classes and on travel days."

Howy

Mathematician

"The task variety is what kept me around. Different problems, different domains, and the rate is fair for the work."

Michael

Computer Scientist

"I don't have the pedigree people usually expect for this kind of work. Getting paid based on what I can actually do, rather than where I went to school, is rarer than it should be."

Molly

Data Scientist

"I'm transitioning from clinical work into health tech. This is the first contract I've found where both my medical and research background are genuinely useful."

Marcus

Physician-Scientist

"Full-time engineering plus NCAA training doesn't leave much room for a traditional job. Being able to work between practices and classes, at engineering-level pay, is the part that changed things for me."
