Amazon Mechanical Turk (MTurk) is a crowdsourcing platform that enables businesses and developers to access a scalable workforce to perform tasks that require human intelligence. These tasks, known as Human Intelligence Tasks (HITs), can include a variety of activities such as data validation, content moderation, and survey participation. Businesses can leverage MTurk to improve efficiency and reduce costs by outsourcing these tasks to a distributed workforce, while workers, often called "Turkers," can earn income by completing them. MTurk is accessible via its website, [mturk.com](https://www.mturk.com), where users can sign up as either requesters or workers.
