Researchers have developed a search engine tool that shows what Google search results appear in different countries or languages, highlighting key differences in the algorithm between regions.

Search Atlas allows users to cross the borders of the "filter bubble" they live in, which Google creates using data on a person's location, language, search history. The tool was created as part of a study conducted by two doctoral students at Carnegie Mellon University and MIT.
