The Self-Citations Checker is a free Chrome extension designed to enhance academic research by calculating author self-citation rates on Google Scholar. By utilizing reliable academic sources such as DBLP, OpenCitation, and OpenAlex, this tool provides a seamless experience for researchers, students, and academics looking to gain insights into citation patterns. The extension automatically integrates into Google Scholar profiles, adding a dedicated 'Self-Citation Rate' column to help users assess the influence of authors more effectively.

Upon visiting an author’s profile, the Self-Citations Checker immediately performs an analysis of self-citation percentages, displaying results with a loading icon for clarity. Users can refresh the data with a single click to ensure they have the most current statistics. While the citation data is extensive, it is important to note that the coverage may not be exhaustive, making the calculated rates valuable estimates rather than definitive figures.
