Maths is where reasoning is most exposed — a step is right or it isn’t. AI systems need mathematicians who can find the flawed step and explain it.
This isn’t advisory work and it isn’t labelling. You’re reviewing real mathematical work and explaining your judgement clearly enough that an AI can learn from it — paid for your expertise, by the hour.
Applied Clinical Judgement connects qualified people to vetted platforms, and Sean Key personally vouches for those he refers. We’re paid a referral fee by the platform on a successful placement — never by you. The roles below are live today.

No live roles match your search.
AI training work is organised by profession, task and software — not by topic or sector. Try your field (for example “nursing” or “Python”), clear the filters, or browse the categories further down the page. The always-open talent pools below are a good place to start.
What the work looks like
Reviewing the model's work
Read what an AI produced in your field and judge whether the reasoning holds — mark where it went wrong.
Setting hard problems
Write the realistic, demanding tasks that separate competent work from confident-but-wrong.
Judging AI answers
Compare two AI outputs and say which is stronger, and why — your written reasoning is what the model learns from.
Common questions
How much does it pay?
Hourly and contractor-based, varying with seniority and role. Every role card shows its pay band. You invoice as an independent contractor and choose your hours.
Can I do this alongside my current job?
Yes — the work is flexible and part-time by design. Check your employer's policy on outside work first; ACJ can't advise on that.
Who is ACJ, and what's your part in this?
