What happened, and the date that matters
Amazon closed Mechanical Turk to new customers on July 30, 2026 and permanently closed it on September 30, 2026. October 30, 2026 was the last day to approve, reject or bonus work.
Amazon's help page says transaction history remains available until January 28, 2027. It names no other download deadline, and in August 2026 it said tasks and their assignment data are removed from an account 120 days after they were created. Anything else you can still reach may already be partly gone, so save it now.
What to save before January 28, 2027
Worker IDs from Mechanical Turk can't be carried over: they can't be verified now that the service is closed, and qualifications earned there don't transfer.
- Download your transaction history from the requester website's transaction history page. It's the one record Amazon says stays available until January 28, 2027, and you may need it for grant reports and audits.
- Save the HTML of every task layout you reuse, with its ${variable} placeholders intact. These import into Tavra as templates.
- Keep the input CSV for each batch you might run again. Each row becomes one task on Tavra.
- Download results CSVs for any batches you can still open. Tavra exports results in the same Input. and Answer. column layout, so the scripts that read them keep working.
- Write down the qualification requirements you used, such as approval-rate thresholds, locations and custom qualification types, so you can rebuild them as Tavra filters and qualification tests.
- Keep your review-board protocol and consent documents. Tavra's compliance pack describes the new platform for an amendment.
How your work maps to Tavra
| On Mechanical Turk | On Tavra | What changes |
|---|---|---|
| Requester | Buyer | The person or organization that posts and pays for work. |
| HIT | Task | One unit of work with its instructions and answer fields. |
| Assignment | Slot | One worker's completion of a task. A task can have several slots. |
| Batch | Batch | Many tasks from one template and a CSV, paid as one order. |
| HIT layout | Template | Your HTML with the same ${variable} placeholders. |
| Auto-approval delay | Review window | Unreviewed work is approved automatically when the window closes. |
| Reject | Reject with a reason | Only for a check agreed before the task started; the worker can dispute it with an independent reviewer. |
| Qualification | Filter or qualification test | Rebuilt on Tavra; scores from Mechanical Turk don't transfer. |
| Masters | Top-worker filter | A paid option based on Tavra's own reputation data. |
| Bonus | Bonus | Paid as its own payment. |
| Prepaid balance | None | Each batch is paid when posted; unused rewards are refunded automatically. |
What Tavra does differently
- The fee is 20% of rewards on most tasks, at least $0.75 per order, with no extra charge for tasks with many slots. Mechanical Turk charged 20%, plus another 20% on tasks with 10 or more assignments.
- Every worker's identity is verified by Stripe before their first paid task.
- Workers see every check before they accept, rejections need a reason tied to one of those checks, and disputes go to an independent reviewer.
- There's no balance to load. Each batch is paid when posted and the unused part comes back automatically.
- Work that's finally rejected is re-run for another worker at no extra fee, and every batch ends with a quality report.
Bring your templates and code
Templates, input CSVs and qualification lists import into a preview before you pay; see importing templates and batches. Code written for Mechanical Turk's Requester API can call Tavra's compatible endpoint after changing the endpoint URL and credentials.
Organizations on Tavra's waitlist before January 28, 2027 get 10 points off Tavra's fee on their first $5,000 of rewards, and we set up your first batch with you.
