# Use the review mode
A powerful feature from **Data**Gym.ai is the review process that helps you to raise the quality of your labeled data. You can activate this inside the project's settings page below the connected datasets.
### Add an reviewer
The section "**Connected reviewers**" shows a list of all connected reviewers. A button to connect a new reviewer is located at the bottom of the table.
To remove the connection the trash icon in each row can be used. This action must be confirmed in a pop-up window.
### More power for reviewers
A reviewer has the same capabilities as a labeler, but he can also review other labelers' work.
Within the [task overview page](/documentation/tasks/process-a-task.md), a second button appears when some tasks are completed and are waiting for a review.
Within the label mode, the usual[ task control panel](/documentation/label-mode/task-control.md) is replaced with the reviewer control where you can leave a comment for the labeler and accept or deny the labeled task.
