Train AI on Clinical Reasoning.
The models shaping the future of AI are only as rigorous as the medical experts behind them. Apply your expertise where it matters, and get paid to do it.
As seen on
This is not busywork.
The most advanced language models still hallucinate drug dosages, confuse contraindications, and invent clinical guidelines. The clinicians who fix this today are building the tools they'll rely on tomorrow — one annotation at a time.
Three steps.
No overhead.
Apply & Qualify
Complete a short clinical reasoning assessment. We evaluate your ability to identify diagnostic errors, apply evidence-based guidelines, and catch unsafe recommendations. No CV required — your clinical judgment speaks.
Get Matched
Based on your training and assessment results, you're matched to projects in your areas of expertise. Cardiology, oncology, emergency medicine, pharmacology, radiology — you choose what fits your background.
Work & Get Paid
Complete tasks on your own schedule. Each task has clear clinical specifications and a defined scope. Payment is per-task, processed weekly, starting at $50/hour.
What you'll actually do.
Write a prompt
Craft precise clinical prompts designed to probe the boundaries of model reasoning — not trivia, but questions that expose flawed differential diagnoses, misapplied guidelines, and hallucinated
treatment protocols.
Review AI output
Evaluate model-generated clinical analysis line by line. Identify hallucinated drug interactions, misapplied diagnostic criteria, and logical gaps in pathophysiological reasoning.
Write the correct solution
Author a complete, evidence-based clinical analysis that demonstrates the correct reasoning. This becomes training signal for the next model generation.
Where models need you most.
These are the clinical domains where your expertise shapes AI into a safer, more useful tool for patient care, documentation, and research workflows.
Cardiology & Critical Care
Evaluate AI reasoning about acute coronary syndromes, heart failure management, arrhythmia classification, and hemodynamic monitoring. Verify claims about treatment algorithms, drug titration, and risk stratification.
Pharmacology & Drug Safety
Review model outputs on drug mechanisms, dosing protocols, contraindications, and interactions. Catch misidentified mechanisms of action, incorrect renal dosing adjustments, and overlooked black-box warnings — including errors in high-stakes dosing tools like gentamicin nomograms.
Diagnostic Reasoning & Imaging
Assess AI-generated differential diagnoses and lab value analyses. Verify sensitivity/specificity claims and catch inappropriate test ordering.
Emergency & Acute Medicine
Audit AI outputs used in clinical documentation and research workflows. Identify errors in clinic note summarisation, post-op dictation, and research assistance tools like citation retrieval and data summarisation for literature reviews.
Oncology & Pathology
Review model outputs on cancer staging, treatment protocols, biomarker interpretation, and pathology findings. Verify TNM classifications, treatment sequencing, and molecular marker significance.

What I love most about DA: it's an actual meritocracy
What I absolutely love about working at DA is the meritocracy. The higher the quality of your work, the higher the reward.
Creating complex coding scenarios, doing deep analysis of models, and synthesizing results are all part of my daily routine, and I love it.

Belated Milestone Post
Been working since March 2024. I honestly feel so lucky to have both found this job and to have been able to keep it for so long.
I thought I might make a few grand max at the start.

100K!
Hit 100k the other day! I do this full time. Not what I originally intended when I signed up, but I've managed so far.
I started as a generalist but I have coding work too.

DA has seriously changed my life
This work has opened up so many opportunities for me and is now enabling me to work full-time independently.
I started as a generalist, then passed the coding eval and have more often than not had plenty of work.

Just hit 75k!!
Started almost a year ago and have just hit this milestone :) I had just graduated from uni when I started doing this and it was a lifesaver whilst I was looking for graduate jobs.
I'm based in the UK and I have a Master's degree in physics so I do a mix of specialist stem, coding, and sometimes generalist projects.

DA saved me, and I wish I could say thanks
In just 2 months I have already paid off my debt that would have taken me around an year to pay back. I can also leave my extra jobs and actually focus on my passion instead.
Working for them has been the best thing to happen to me so far.

Hit the 10k mark in one month : )
I have earned 10k in a month (my first month started at the end of April). I needed this and will definitely continue working with them.
I plan to keep working and be able to pay for a masters maybe in the fall.

Broke 130k this month!
I love that I can switch between coding tasks and those with rubrics, and that the work is always changing, so it never gets boring.
The taxes hurt, but it is worth it to help support the services like free healthcare here in Canada.

$40k - I Love You Data Annotation <3
Data Annotation has saved my ass financially and allowed me to help out my loved ones. Couldn't ask for a better job.
I've been working about 2-3 hours a day, 5 days a week, for just over 2 years.

Treated DA as pretty much full time for the past 3 years and its been a god send for me.
I've saved a huge amount of money working from home, managed to work on a part time masters degree, and also been able to spend more time on myself.

My personal experience with DA [CODING]
In less than 2 months I've made a little over $20k, which honestly still feels surreal typing out.
A lot of it feels like real engineering/problem-solving work — debugging code, evaluating implementations, reasoning about edge cases.

Actually can help pay student debt now
This made living as a grad student actually affordable. In 2 weeks I just over doubled what I normally make.
Half of what I need to do in grad school is writing, so writing practice has been well needed.

Thanks DAT, I've been able to live an awesome life because of this job. Traveled to 28 countries, built a wrap around deck for my mom, created a massive garden, and so much more!
You can do it too, keep up the good work people!

Jumping on the Milestone bandwagon
It's been a long, almost 3 year journey. Coder, self taught, and the first year or so was really, really tough. But I have no words for how thankful I am for DA.
I've had some amazing jobs in my life, but none compare to the constant challenges and rewards of this one.
