MassEditRegEx is an extension that allows for the editing of many pages at a time like Replace Text, but while they have similar functions, this extension has a few differences:
- Replace Text is the wiki version of the Find/Replace feature found in word processors. This extension, by contrast, is more about adding specific text to pages that don't already have it.
- Replace Text is best used to fix bad links/wiki words and/or removing/modifying text.
- Replace Text can work across entire namespaces and categories, whereas this extension requires a specific list of pages for alteration.
