Word Replacer III

About

Word Replacer III
Automatically replace any word or phrase on any webpage — as it loads, every time, without lifting a finger.

Define a list of Find → Replace pairs and Word Replacer III silently rewrites matching text across every site you visit. Great for renaming things that annoy you, customizing UI text, fixing abbreviations, building immersive reading experiences, or just having fun with the web.

What you can do:

Replace simple words, phrases, or complex patterns (full RegEx support)
Swap two words with each other simultaneously

Control capitalization per rule — maintain the original case or override it exactly

Restrict any rule to specific sites only, or run it everywhere

Organize rules into groups and toggle entire groups on or off at once

Add replacements instantly from the toolbar without opening the settings page

Test your rules live before saving — type a sentence and see the result in real time

Export and import your list as JSON, or share it with anyone using a generated share code

Get nudged to back up when your list grows large and you haven't exported in a while

Built for lists of any size. Paginated interface, live search across all entries, bulk enable/disable, sort, find duplicates, and undo delete — so managing hundreds or thousands of rules stays manageable.
