Amazon Mechanical Turk (MTurk) is a marketplace for completion of virtual tasks that requires human intelligence. The Mechanical Turk service gives businesses access to a diverse, on-demand, scalable workforce and gives Workers a selection of thousands of tasks to complete whenever it's convenient.
Amazon Mechanical Turk was created because we know there are many things human beings do much more effectively than computers, such as identifying objects in a photo or video, performing data de-duplication, transcribing audio recordings, or researching data details. Requester customers are able to send these tasks to the Mechanical Turk workforce. Traditionally, these tasks have been accomplished by hiring a large temporary workforce (which is time consuming, expensive, and difficult to scale) or have gone undone.
In 1769, Hungarian nobleman Wolfgang von Kempelen astonished Europe by building a mechanical chess-playing automaton that defeated nearly every opponent it faced. A life-sized wooden mannequin, adorned with a fur-trimmed robe and a turban, Kempelen’s “Turk” was seated behind a cabinet and toured Europe confounding such brilliant challengers as Benjamin Franklin and Napoleon Bonaparte. To persuade skeptical audiences, Kempelen would slide open the cabinet’s doors to reveal the intricate set of gears, cogs and springs that powered his invention. He convinced them that he had built a machine that made decisions using artificial intelligence. What they did not know was the secret behind the Mechanical Turk: a chess master cleverly concealed inside.
A Human Intelligence Task, or HIT, is a question that needs an answer. A HIT represents a single, self-contained, virtual task that a Worker can work on, submit an answer, and collect a reward for completing. HITs are created by Requester customers in order to be completed by Worker customers.
Click the "Get Started with Amazon Mechanical Turk" link in the upper right corner of the Worker website to fill out an account request. You will be asked to provide your name, email address, and password. In addition, you will be asked to agree to the Amazon Mechanical Turk Participation Agreement and provide your country of residence. We will review your account request and email you with an outcome within 3 business days.
You can view and edit your account information by accessing your Account Settings page. Your MTurk Worker account is associated with your Amazon.com account so you will be redirected to Amazon.com to change your name, email address, and password.
You can view and edit your contact address via Amazon Payments. You can change your bank account information here.
You can view and edit your contact address on Amazon.com. If you have the option to transfer your earnings to your local bank account, you can change your bank account information here.
To work on a HIT, sign in to the Worker website and visit the HITs page. There you will see a list of HITs you are qualified to work on. Click on the "Accept & Work" button for the HIT you want to work on. Complete the HIT according to the Requester instructions, and click the "Submit HIT" button. After you submit your results for the HIT, another similar HIT will be presented for you to accept.
Requesters have a great deal of control over the content and design of their HITs. In some cases, HITs created by Requesters may be hosted externally on their own servers instead of systems managed by Amazon Mechanical Turk. Because MTurk isn't directly involved in the creation of HITs posted by Requesters, you should always take steps to protect yourself from scams and phishing attempts. For example, do not respond to HITs that ask you to provide your email address, password, or other personal data. When MTurk asks you for your Amazon sign-in information the URL in your browser will end with amazon.com. If a Requester's HIT appears suspicious or violates our Acceptable Use Policy, please use the "Report this HIT" link on the HIT preview page or the HIT page itself and select "Policy Violation" to report it.
Requesters determine whether to approve your work and pay you within 30 days after you submit your Human Intelligence Tasks (HITs). Amazon Mechanical Turk does not determine whether or when to approve or reject HITs and does not estimate when your HITs will be approved. Completing HITs accurately will help ensure that Requesters will want you to continue to work for them. Read instructions thoroughly, answer HITs accurately, and return HITs you are unable to complete correctly, to build a positive reputation as a Worker. Keep in mind that returned HITs will not affect your rating.
In the event you have questions about the content of a HIT or the approval status, you can contact the Requester directly.
Requesters can specify a HIT's "Allotted Time" or how long a Worker can hold on to a HIT. Once the Worker accepts the HIT, a timer begins counting up to the HIT's allotted time. This timer is visible to the Worker on the Worker web site. When the timer reaches the HIT's allotted time, the HIT is made available for other Workers to accept and work on. This ensures that work is completed in a reasonable time period.
Amazon Mechanical Turk limits the number of HITs Workers can do on a daily basis as a means of combating conduct that would violate the Participation Agreement, including, for example, use of robots, scripts or other automated methods to complete HITs and ensuring that Workers are exercising their independent, human judgement to complete HITs.
A Requester may reject your work if they believe the answer is wrong, the HIT was not completed correctly, or that the instructions were not followed. If you believe that your work was rejected in error, you may decide to contact the Requester directly.
Your name and e-mail address will be made available to the Requester when you submit the "Contact the Requester of this HIT" form. After you have sent your message, you may need to wait a few days for a reply. Some Requesters do not monitor their messages every day.
No. All work product that you submit to answer a HIT on MTurk is the property of the Requester.
You may only use the HIT content that Requesters publish to perform the HIT. Do not share the HIT content (or your answer) with anyone except the Requester, or with MTurk to report abuse.
If you see a HIT that violates the Amazon Mechanical Turk Participation Agreement including the Acceptable Use Policy, please report the HIT by clicking on the "Report this HIT" link so that we can investigate.
When you complete HITs on Amazon Mechanical Turk, you are accessing the Internet to perform work for Requesters that may not be Amazon. We recommend that you secure your computer with the latest operating system security updates and virus protection software, update your browser and plug-ins with the latest versions, and use caution when directed to other websites or asked to download software.
When the Requester approves your submitted HIT, Amazon Mechanical Turk account will automatically display your earnings on the Dashboard and Earnings pages.
All amounts paid will be in US Dollars or Amazon.com gift cards.
You will be able to schedule a transfer of funds from your available earnings balance by visiting the Account Settings page. Your earnings to be automatically transferred to your preferred payment method on the schedule you selected.
As a security requirement, if you are a new Worker, there is an initial holding period before rewards are transferred to your earnings balance. Your rewards are held until you have been active on Amazon Mechanical Turk for at least 10 days, starting from the day you submit your first HIT. After this initial holding period, you will be able to transfer funds from your earnings balance by visiting the Earnings page. You are limited to one transfer per calendar day.
Your transfer balance includes earnings for HITs approved at least one day prior to your transfer date.
Go to the Account Settings page to Manage Payment Preferences and select a transfer schedule for your earnings. You have the option of scheduling payments every 3, 7, 14 or 30 days. If you change your disbursement schedule or method of disbursement (Amazon.com gift card or U.S. bank account transfer), these changes will take effect for your next scheduled transfer.
You can transfer your earnings to your U.S. Bank account or to an Amazon.com gift card.
You can transfer earnings to an Amazon.com gift card. Eligible international Workers also receive the option to transfer earnings to a U.S. bank account.
All Amazon Mechanical Turk earnings will be paid in U.S. Dollars. For Workers eligible for the U.S. bank account transfer option, you have the option of using third party service providers like Hyperwallet in order to receive payment in the local currency of your country. These third party service providers will transfer earnings from your account with such service provider to your local currency bank account. You may use a third party service provider of your choice to transfer earnings from your U.S. bank account to your local currency bank account. You will receive instructions on the Earnings (https://worker.mturk.com/earnings) page when this transfer option is available to you.

A bonus is an additional grant of money from a Requester. A Requester can choose to pay a bonus in addition to the stated reward for completing a HIT. Bonuses are granted at the Requester's discretion and are usually paid to Workers who do particularly good work.

A Master Worker is a top Worker of the MTurk marketplace that has been granted the Mechanical Turk Masters Qualification. These Workers have consistently demonstrated a high degree of success in performing a wide range of HITs across a large number of Requesters. We leverage statistical models that analyze all Workers based on several Requester-provided and marketplace data points to make that determination. Some of the key categories of data that are considered to be granted and maintain the Masters Qualification include the Worker's ability to consistently submit high-quality results (as indicated by Requester approval rates and other related factors), marketplace tenure, and variety of work performed. Master Workers have access to work that requires a Masters Qualification.
Mechanical Turk automatically grants the Masters Qualification based on statistical models that analyze Worker performance based on several Requester-provided and marketplace data points. Those who score the highest across these key data points are granted the Masters Qualification. Workers cannot apply for this status. To receive the Masters Qualification, try tasks across a variety of Requesters and consistently submit a lot of high quality work.
Yes, the Masters Qualification can be revoked if the Worker's performance declines and he or she no longer scores highest across Requester-provided and marketplace data points, or the Worker otherwise violates our Participation Agreement. If Workers have the Masters Qualification revoked, they will have an opportunity to improve and will be eligible to regain the Masters Qualification in the future.
Requesters use Premium Qualifications to access the contributions of those Workers that are best-suited to their workloads. To become eligible to complete HITs that use Premium Qualifications, Workers can complete Profile Information HITs available here. Please note that some Premium Qualifications are only available for Workers in certain locations.
No. Providing information via Profile Information HITs is optional. You can complete as many or as few Profile Information HITs as you choose. Certain HITs are only available to Workers who have completed certain Profile Information HITs.
Once your Profile Information HITs have been processed, which may take up to 30 days, you can view your related Premium Qualifications on the Qualifications Assigned to You tab.
Amazon Mechanical Turk will re-publish the Profile Information HITs on a periodic basis. Workers can be granted new Premium Qualifications by changing their responses when re-taking Profile Information HITs. If you want to remove any of your Premium Qualifications at any time, please contact us and we will remove you from that Premium Qualification.
We use your Profile Information HIT responses to associate Premium Qualifications with your Worker ID, so that Requester HITs requiring those Premium Qualifications can be made available to you. We will not otherwise use this information for any purpose (including marketing purposes) without your consent. You can contact us at any time to opt-out of Premium Qualifications and revoke your consent for us to use the profile information you provided. To learn more about our information practices, please read our Privacy Notice.
