FamilySearch Batch Checker is a free Chrome add-on developed by chaoticshiny. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This program aims to streamline Society for Creative Anachronism (SCA) name documentation searches by checking the validity of batch numbers on the FamilySearch website.

The add-on works by inserting either "(Good Batch)" or "(Bad Batch)" after batch numbers in FamilySearch search results, in accordance with the batch designations provided in the SCA's official documentation website. This feature allows SCA members and researchers to easily identify which batch numbers are valid and can be trusted for accurate name documentation.

With FamilySearch Batch Checker, users can save time and effort by quickly filtering out invalid batch numbers. This tool proves to be a valuable asset for those involved in SCA research, ensuring that the name documentation process is efficient and reliable.
