Amazon Mechanical Turk

Amazon Mechanical Turk is an online market place that automatically pairs tasks that are simple (yet too hard for a computer to do) with people who want to do them for money (often just a few cents).

The tasks are available to be executed and it is available in units of HIT(Human Intelligent Task). As a Mechanical Turk Worker, you can search and browse for HITs and click on the ones that interest you. After you accept the HIT, follow the instructions to execute the task and get paid paid through your Amazon Payments Account once the Requester approves the work.

Mechanical Turk Requesters are the ones who offer HITs. Data cleanup, categorization, content creation & moderation, feedbacks are a few of the common categories of tasks on offer. Registering to be a Requester provides the job providers access to an on-demand scalable work force who are flexible and provide high quality cost-effective results within minutes. And the payment needs to be released only if you're satisfied with the results.

At this point of time, the web portal claims to have more than 4.5 lakhs of HITs on offer.
