SuperTextSwap/Replace text on a webpage

Replace text on a webpage

Start with one simple rule. Understand the result, its scope and how to return to the original page.

What it is for#

SuperTextSwap finds matching webpage text and changes what your browser displays. Use it for reading terminology, brand-copy previews and test-page text changes. It is not a server-side content editor.

Set up a replacement#

  1. Open the extension on an ordinary webpage.
  2. Enter text to find, such as “idea”.
  3. Enter replacement text, such as “possibility”.
  4. Select the current-domain scope and add the rule.
  5. Inspect the page. Use Apply now if needed.

The homepage demo only changes its own sample. Install the extension to work on other webpages.

Control & restore#

Manage rules in the workbench. After disabling or removing a rule, reload the webpage if the old replacement is still visible. Do not assume deleting a rule automatically restores existing text.

Dynamic pages may insert new content that matches active rules. Narrow the URL or element scope to reduce unintended changes.

Before changing form fields#

Inputs and rich-text editors can be included through separate options. Review their content before submitting a form: the changed text may be sent to the website. Reading-only workflows usually do not need these options.
