Data Annotation services made easier

Annotate data quickly and earn money with Data Annotation Platform.

Data Annotation is time-consuming but worth the trouble

You might have heard the saying that quality data is the new oil. There’s so much value hidden in images, sound, video, and text. All you need to do is tap it.

CarLens - recognize and collect your favourite cars

Use Machine Learning to detect different car models

CarLens is a mobile application for both iOS and Android that lets you recognize cars you find on the street. It uses Augmented Reality and an AI-based solution to detect cars you see through the smartphone camera.

While creating CarLens, we created a custom software for data annotation where we’ve leveraged mobile solutions and created a simple app.

Our experience with CarLens taught us that solving Machine Learning problems is not easy. The data annotation is a crucial issue behind a model’s accuracy. We’ve learned how important a quality data set is and how important is also the way you manage it. That's our key to success.

Make your data meaningful - the process of data labeling and classification

The process of annotation is most dependably done by human beings. It might sound low-tech, but it’s not that easy. Several steps need to be followed with precision and focus.
Collect your data

Choose the type of data that suits your purposes, and collect as much as you need.

Define classes

Define the categories for the classification of your data. In the case of Carlens, we used car models.

Describe each class

Write up the characteristics for each class and create a rule book. Your annotators will need it when they run into less obvious cases.

Begin annotation

Get to work! If you have a lot of data, you’ll need a team of annotators. Manual data annotation takes time.

What kind of data you can annotate?

In our multi-channel reality, one type of data might not be enough. Consider what data sets can do the most for your business. You can annotate all of the major data types on our platform, on various classification levels. Let’s work together

We offer binary and multiple choice photo sets, giving you extra flexibility.


Labeling video data can be a challenge. We want to make it easy for your annotators.


Annotate sound files based on type, author, the genre of music - and much more.


Text data can be the basis for language learning projects, but it’s not limited to that use.

The right process is the key advantage

Whether you need to craft the idea for a completely new machine learning product or evaluate the quality of an existing data science project, you need the right process.

Data Annotation workflow focuses on three stages:
