How it works

Define your own find-and-replace rules once. The extension applies them automatically on every page you visit.

Three steps

  1. Install the extension from the Chrome Web Store.
  2. Open the popup and save a find → replace pair.
  3. Browse normally. Matching text is replaced automatically.

Rules

  • Plain-text rules match literally (special characters are safe).
  • RegEx rules match patterns, including capture groups like $1.
  • Rules run in order, top to bottom. Later rules see earlier results.
  • Organize rules into collections; disable any collection or rule without deleting it.
  • Scope a rule to specific sites, or leave it on for all sites.
  • Skip inputs, textareas, or any element with per-rule ignore selectors.
  • Back up and share rules with import/export (JSON).

Where replacement applies

  • Page text, including content added or updated dynamically.
  • Input and textarea values, plus placeholders.
  • Rich-text editors (contenteditable), such as social compose boxes.
  • Pages inside frames, and open shadow-DOM components.

Replacement runs locally in your browser. Page text never leaves your device. See Privacy and Security.

Limits

Browser pages like chrome:// settings and the Web Store itself don't allow extensions to run. Local files need a one-time opt-in. Details: Compatibility · Troubleshooting · FAQ.
