Frequently asked


Do I need to provide a labeling tool?

We prefer using our labeling tool with specialised features that help us maintain the quality of the labels. However, we can also integrate with third-party tools of your choice.

Can you annotate international languages?

Yes. We support all major Indian languages alongwith languages like Spanish, Japanese and others. For international languages, we utilise our partners in the native countries to annotate.

What if my data is domain specific?

Our labeler pool consists of generalists as well as specialists who can handle medical, financial and other type of datasets. We can also provide you labelers from a specific geographic location.

Can you also capture data for us?

Yes. We can create raw data for text, audio as well as image based systems. Get in touch with us for more details.

How do I measure the quality of the labels?

We do it for you during the review phase. You can also label a small portion of the data and match it with our labels to come up with a quality measure.

What if we need you to re-label a batch?

If the delivered labels do not match up to the accuracy measure agreed upon in the SLA, we re-label the entire batch free of cost.
