Frequenty Asked Questions
Why would you use our service?
We take over the hustle of doing data annotations and save you the time to focus on what matters.

We are annotating data for years and have the right tools and knowledge to carry out the task effectively and at the best quality.
How long does it take?
Typically it would take 1-3 days, however, it is also depending on the data set.
Is it possible to annotate domain-specific data?
We carry out any kind of annotations that a "regular" person can do. In cases that require deep domain-specific knowledge (e.g. "classify skin diseases on photos"), it is unfortunately not possible at this point of time.
Is my data set protected?
We are using our own tools, however, internally it is required to upload your data set to a crowd-sourcing platform for a limited amount of time that is needed to execute the annotation task. We will use a crowd-sourcing platform with appropriate data protection rules.

We need to note that every crowd worker receives a small piece of your data for annotation. Purely theoretically, it is possible to organize thousands of workers and partially reconstruct your data set piece by piece. In practice, it is super unlikely and has never happen so far. In case of any concerns, please do not hesitate to write us an email at help@annotateai.co, and we will be happy to answer all your questions.

After the completion of the annotation task, we will remove all your data from our directory.
When do I have to pay?
For smaller data volumes - 50% before and 50% after.
For higher data volumes - the payment can be done batch by batch.

It goes without saying that if for some reason we do not deliver, you will get a 100% refund.
Is there any min/max limit on a number of annotation tasks per order?
Usually, there are no limits on a number of annotation tasks.
In which format will I receive the annotations?
In any format of your choice: JSON, XML, etc.
