iNatty Localness Checker is a Chrome add-on designed to enhance the iNaturalist platform by providing users with local and global observation statistics for various species. This tool allows users to view the Place Total, Global Total, and the percentage of observations within a specified location. By highlighting local standouts, it aids in identifying species that are particularly significant to a given area.

The add-on features basic sorting options, enabling users to organize data by Percent, Total, and Local metrics. While the Global Total may include a broader range of observations beyond just wild specimens, it remains a valuable resource for discovering endemic species that are less common in captivity. The tool effectively addresses user biases inherent in observation data, making it a useful asset for any iNaturalist user.
