Amazon Mechanical Turk review
Launched in 2005 and owned by Amazon, Amazon Mechanical Turk (MTurk) is a crowdsourcing marketplace where companies outsource microtasks such as AI training data collection, data entry, and image annotation. Clients post tasks and set worker pay; the crowd completes them to earn money.
Human Intelligence Tasks (HITs) include:
- Data collection for AI/ML model development
- Data annotation, labeling, and tagging
- Online surveys
- Machine learning model development support
Pricing
- MTurk charges 20% on the worker’s pay
- An additional 20% fee applies to tasks with 10 or more assignments
- Master-qualified workers cost an extra 5%, though clients report this does not consistently produce higher-quality work
Worker earnings (2026): Consistent users report earning $10–$30/day depending on experience and HIT availability. Reviews on Trustpilot are mixed, with common complaints about unexplained account bans and application rejections.6
Broader context: In 2026, AI automation is reducing demand across microtask platforms. The tech sector cut 55,775 jobs in the first 74 days of 2026, with approximately 9,238 (around 20%) explicitly attributed to AI implementation.7 Independent reviews note that “AI has gutted many other microtasking apps,” and task availability on lower-tier platforms is shrinking.8
Why are we looking for alternatives to Amazon Mechanical Turk?
Lack of user-friendliness: Some requestors find MTurk less intuitive than alternatives, particularly when setting up tasks and managing workers.
Communication difficulty: Data collection clients report issues communicating with workers on the platform.
Quality concerns:
- Studies have identified data quality issues in MTurker responses.9
- A recent study estimated that 33–46% of MTurkers use large language models in their responses to text production tasks.10
- Some clients also flag limited English proficiency among parts of the MTurk crowd.
Crowd size discrepancy: While the company cites approximately 500,000 registered workers, studies indicate around 100,000 are actively available on the platform at any given time.[/efn_note]11
