See Hub, Crowtado and Claru side by side. Check what each one advertises, run the numbers with your hours and choose with more confidence.
The basic idea is simple: a task appears, you complete it and the platform reviews it. Only approved work is paid. Some platforms also pay a separate bonus when you invite someone.
Check whether the platform accepts people from your country and supports your device.
Create your account and complete the checks it asks for.
Only take tasks you understand, then keep an eye on what gets approved.
Once you reach the minimum, request a payout using the method available in your account.
The headline rate matters, but it is not the whole story. Compare the task type, the rules and what each source actually confirms.

Takes you to the official site
If you join Hub or Crowtado through our buttons, StackPick may earn a commission — nothing is deducted from you. The Claru button goes straight to its official site.
Use the same number of hours for both and adjust each rate. You can compare the scenarios instantly — without treating an advertised amount as a promise.
This is an estimate. Your actual result depends on available tasks, approval, fees, taxes and a completed payout.
Hub publishes US$0.50 for each approved hour from a direct referral and US$0.25 at the second level. Move the sliders to test a scenario.
Hub runs a real contributor platform and publishes its rates through an API. That still does not mean every person will get tasks or every hour will be approved. Use approved work and completed payouts as your reference; screenshots and projections are only examples.
It depends on the project. Country, language, device and profile may limit access even when a platform works globally. Always use your real location — a VPN or false region can get an account blocked.
We checked the public rates, contracts and payout rules so you can start small and make a better decision.
