Name banks are databases or collections of names that can be used for various purposes, such as naming characters in a story, generating usernames, or coming up with company or product names. These names are typically organized into categories based on themes, styles, or origins, making it easier for users to find one that suits their needs. Some name banks also offer name ideas based on attributes like gender, age, or popularity. Users can browse through the names in a name bank or use filters to narrow down their search and find the perfect name. Name banks are a valuable resource for anyone who needs inspiration or assistance in naming something.
