Skelbimų Fact Checker is a free Chrome extension designed to enhance user engagement on various advertisement portals. This tool allows users to comment on specific listings, sharing their opinions and observations with others. It serves as a platform for users to express thoughts regarding advertisements, although it is important to note that these comments are subjective and may not always reflect the truth.

To utilize the extension, users simply need to install it and navigate to one of the supported advertisement sites. A notification indicator next to the extension icon will display the number of comments associated with a particular listing. This allows users to easily contribute their insights or read comments from others who have viewed the same advertisement, fostering a community of shared experiences.
