Unlabelling is a free Chrome add-on developed by OVD-Info. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This add-on aims to abolish the labels of 'foreign agents' on media websites. It is a response to the laws on 'foreign agents' in Russia, which many people find discriminatory.

The add-on provides a platform for over 260 thousand people who demand the repeal of these laws. OVD-Info has collected signatures and submitted a bill to the State Duma for the abolition of 'foreign agency' legislation. They have also analyzed the discriminatory aspects of these laws and provided a report on the matter.

Unlabelling allows users to determine their own reality by removing the labeling on 'foreign agents' media websites. In place of these labels, users will see advertisements of organizations that have signed the petition against the legislation. The add-on is open source, and more information can be found on the OVD-Info GitLab page.

With Unlabelling, OVD-Info aims to empower individuals and raise awareness about the discriminatory nature of the 'foreign agency' legislation in Russia.
