Manage Classes at a Team-Level

All of your team's classes are stored both team-wide, and at a dataset level in the new Classes page, allowing you to easily add classes to new datasets, and manage classes across your existing projects.

See Which Frames Have Loaded

Until now, exporting image or video files from V7 was only possible if the file contained an annotation. Unlabelled files can now be exported using the CLI.

Export Unlabelled Files


Until now, exporting image or video files from V7 was only possible if the file contained an annotation. Unlabelled files can now be exported using the CLI.

Only Drag Selected Annotations 


Selected labels are now only moveable on the second click. If you've ever had to hit Ctrl+Z after accidentally moving a label out of position, this one's for you!

See Dataset Progress at a Glance


Dataset thumbnails now show how many files have been completed as a percentage and a progress bar to give you quick insights into how your projects are coming along.

Add up to 5 Class Thumbnails 


To help you and your team more easily identify when a class will apply, you can now upload 5 thumbnails from your local device.

Improved Video Sub-Annotations

Attributes, Instance IDs,andText now exist independently of key frames in the video timeline, allowing you to more easily add them to the frames to which they apply. This prevents teams labelling video from having to manually add attributes to sequences that are interrupted by a key frame

Negative Filters

Quickly determine which files do not contain specific classes. Click on a filtered tag, class,annotator, item, or workflow stage twice to exclude it from your filters.

New APIs for Registering and Uploading External Files


Paired with brand new documentation, we've released a new upload API to simplify standard uploads, as well as uploads from external storage.

Text Sub-Annotations for Tags


Add an extra language layer to your tags. All tag classes now include the ability to include text as a subannotation.

Webhook Signatures & Documentation


All webhook payloads now include a V7 signature. We've also bolstered our documentation to help you easily set up webhooks in your datasets.

Tag During Upload


One of our most asked-for features is now possible via the new API - you can now tag and import files simultaneously.

🛠 Fixed an issue that prevented files from being moved and assigned when using complex filter parameters.
