    • The image segmentation comes with a bitmap export for each individual class

    • The image segmentation data will also be a part of the export functionality

  • Improvements for the import feature:

    • It delivers more useful and informative error messages

    • We simplified the json import by reducing the required fields

  • Project improvements:

    • The project task-list now shows badges which indicates wether the task was pre-labeled and imported

    • Administrators now have the power to unassign labelers from a task


  • Workspace: Moving polygon points wont stick to a virtual grid so you have more control about it

  • Label configuration: You now can use question marks for the field description which can help the labeler understand the task better


  • Workspace: Objects of the type line now cant be drawn outside the workspace area

  • Workspace: Duplicating geometries now works even the geometry is very close to an edge

June 21, 2020

New features:


  • The workspace task-control buttons now show an clear text instead of icons

  • We overall make it easier to click action-icons like the delete button

Jule 08, 2020

New features:

  • With the shortcut CTRL+V you can now copy a geometry and its classifications to speed up your daily work with

  • The AI-assisted pre-labeling now supports also polygon geometries


  • The line geometry appears now like a polyline. Untill now a line was defined with the starting point and end point. But now you can use multiple points and also add points like on the polygon.

  • In addition the helping points are removed from the polygon geometries. Instead, an addition point can be created just by hovering and clicking over the line between two corner points of the polygon.

  • To support you on the review process every geometry can now be commented.

  • The label configuration and the entry list are now sorted by the shortcuts.

  • Simplified the configuration for the AI-assisted pre-labeling.


  • Changed the calculation for the AI-assitsted labeling if a polygon should be replaced with a new one.

  • On fastly using the shorcuts the task may could not be completed.

June 23, 2020

  • Let do the boring tasks for you and get the bounding boxes from the brand new pre-labeling feature.


  • In order to priorize other features we deactivated the benchmark tool. It will be available later.

  • Now it is possible to hide single geometries not only groups.


  • Fixed some bugs within the workspace.

May 27, 2020

New features:

  • Our latest release comes with a set of brand new tools for AI-assisted labeling. Speed up your labeling process by using a variety of tools, such as Paint fill, Rectangle selection, and Click. You can also now refine the predicted labels by setting additional points in your image. Check out our documentation for a complete overview.

  • Measure the labeling performance of your team members with the new Benchmark Mode. This feature allows you to review the accuracy of your team members while labeling images. The Benchmark Mode is still under development but will be fully available soon.


  • Delete the images in your datasets faster with multi-selection.

  • Use our new dynamic cancel button in the label mode to cancel or deselect your current action. Thereby, you can now work on your labeling tasks without using keyboard shortcuts.

  • Hide helping points while editing polygon geometries when points are too close to each other.

May 13, 2020

New features:

  • You are not sure, if DataGym is the right tool for you? Just use the new preview of the label mode at or request a demo.

  • Copy existing geometries or image classifications within the label configuration. The copy got a new tag, export key and in case of a geometry also a new color and if possible also a new shortcut. All the nested classifications are reused to speed up the configuration job.


  • Removed classification types radio & select. Both are replaced with the new type option to simplify the label configuration.

  • Removed also an error message when the last task was processed. Now you get a success message because all your jobs are done for the moment. Enjoy the day.

  • The preselected color for new geometries within the label configuration rotates.

  • Some UI/UX improvements.


  • Some translations were changed.

  • Set boundaries to the drawing mode so geometries cannot be moved outside of the image.

April 24, 2020

  • Add a context menu to label mode so you can change the geometry type if necessary. Read more within the documentation.

  • Use the review feature to raise the quality of your labels.

  • Added some statistics to the project overview.

  • Get an overview about your limits within your account page to not raise any restrictions.


  • Some minor changes to make your life easier.


  • Inverted the arrow key direction to move the image within the label mode.
