Write and review accurate responses
Read what an AI assistant has written and judge whether it's correct, helpful, and well-explained. Write a better version where it isn't.
Check facts and label information
Tag images, text, and short clips against clear rubrics so the data is organised and usable for training. Careful, detail-focused work.
Solve problems in your area of strength
Work through coding, maths, science, or writing prompts and show the right way to think them through. Your subject knowledge is the point.
Work in your own language
Help AI handle languages and regional context properly. Fluent speakers of any language are in demand, especially outside English.
Review specialist material
Clinicians, lawyers, scientists, and qualified engineers review domain material where the credential genuinely matters. Specialist rates apply.
Record everyday tasks
Where projects call for it, capture short clips of normal activities from a phone or simple kit. No technical background needed.

People earning with Kleum
"It fits around my actual life."
I pick up tasks in the gaps — an hour after the school run, twenty minutes before bed. The pay isn't life-changing on its own, but it lands every Friday without fail and it's added up to something meaningful over the year.
"The work itself is genuinely interesting."
I started doing basic tagging on my laptop. After a few months I was reviewing other people's work, which pays more. I've learned more about how modern AI is actually built doing this than I did from anything I read about it.
"Real money, paid on time, no nonsense."
I'd tried a couple of other platforms before and one of them never paid out. With Kleum the pay is shown before you accept a task and it shows up in my account every week. That's all I needed.
"My clinical training, paid properly."
I joined the specialist register as a verified clinician. The contracts I'm matched to genuinely need a medical background, and the rates reflect that. It's the most useful side income I've ever had outside of practice.
