Every annotation team needs to organize its work, but no one wants to stop working in order to track work. Supervisely Issues allow keeping the work of a huge labeling workforce all in one place.

What are Supervisely Issues?

Data Labeling is about collaboration at scale: managers, domain experts, data scientists, inhouse labelers and dedicated external labeling teams. Hundreds of people are involved in. Also, this complicated process requires multi-stage reviewing and correction to guarantee quality. And it is hard to organize the entire process without specially designed tools.

Supervisely Issues are built in cooperation with professional labeling teams and help to:

  • create, organize and inspect issues on invalid images and objects.

  • share, discuss, resolve them with your labeling team

  • track progress and receive notifications in real-time

  • collaborate right in annotation tool without switching interfaces back and forth

Github Issues are the perfect example of efficient collaboration between thousands of developers. We at Supervisely got best practices from Github Issues, adopted them to labeling scenarios and integrated into annotation tools by keeping well-known user interfaces.

Organize + Search + Filter

Issues has its own section in every team. There are two types of issues: private and public ones. Private issues help to discuss project-related questions and are available only for team members. Public issues are designed to keep everybody in your organization on the same page, share ideas, hear all voices, consider all options — and establish consensus.

A big part of managing issues is focusing on important tasks and keep plans up to date simultaneously all in one place. The search box at the top of the page gets you there faster. You can filter search results by type (public/private), author, assignee, project, job, and open/close state. Sorting is also available, for example by most commented or recently updated.


A typical issue looks like this:

Issue page

  • Title and description describe what the issue is all about

  • Links associate your issues with any Supervisely entities like projects, labeling jobs, neural networks and so on and help you categorize and filter your issues based on that

  • Assignees are responsible for working on the issue

  • Comments allow anyone with access to the Issues to provide feedback

  • Markdown support — it is a lightweight and easy-to-use syntax for styling all your comments: add tables, images, coloring, lists, links and so on

Once a lot of issues are collected, it is hard to find the ones you care about. Assignees and Links sections are used to categorize and filter issues. To assign users just click the corresponding gear in the sidebar on the right. To attach links, just copy and paste URLs into the comment text block, they will be automatically parsed.

Integration into annotation tool

Integration into labeling interfaces is an essential part of the effective labeling process:

  • place an issue to specific objects, images or some image regions

  • see the entire context of a conversation

  • organize real-time discussion of edge labeling cases

  • get instant feedback and guides right from comments

  • filter images with issues on the right panel

  • change issue positions or move discussion popup so that their placement makes sense

  • resolve issues from labeling interface, cause no one wants to stop working in order to track work

Items to resolve

You can close the entire issue or you can create a single issue and attach a lof of items (for example images or projects) to this issue. They will be in the “Items to resolve” page. Every item has its own discussion thread.


Supervisely’s issue tracking is special because of our focus on collaboration and visualization tools during labeling. Every item can be discussed and resolved separately. For images and objects, a user sees initial labels (when the issue was created) and a final result.

It is especially useful for tracking how labeling mistakes are fixed over time. Managers and reviewers can easily track changes by comparing the differences between initial and final labels.

Notifications & Changes

Issues evolve over time: titles change, items resolve, new items appear, discussions become long, issues get new assignees. Changing history in conversation gives better insight into these changes.

Notifications provide important updates about the conversations and activities you’re involved in. Users don’t miss relevant information and stay informed of what’s going on. Notifications are available through email or right in Supervisely dashboard.
