Wordshift

Find and replace text in one tab or automatically across sites, with rules you control.

Wordshift finds and replaces text on web pages. Use Quick Replace for a one-off change in the current tab, or save rules that run automatically on the sites you choose. Quick Replace - Open it from the toolbar or with Alt+Shift+F. - See a live match count, highlight matches, and step through them one at a time. - Replace one match or all of them. Changes stay in that tab and reapply after reloads until you remove them or close the tab. Automatic rules - Run on every visit to the sites you choose, including text that loads later. - Match anywhere, whole words only, or with a regular expression, with or without matching case. - Limit a rule to certain sites, or run it everywhere except certain sites. - Organize rules into groups, turn groups on and off, and pause automatic rules on a site. - Test a rule on sample text before saving it. Safe by design - Wordshift changes only visible text. It does not run code from rules, rewrite HTML or scripts, or touch form fields and what you type. - Every change can be undone. Minimal permissions - No site access at install. Quick Replace works on the current tab after you open it. - Automatic rules ask for access only to the sites they use, and you can remove that access at any time. Private - No account, analytics, telemetry, or network requests. Rules and settings stay in your browser. - Export rules as a JSON file and import them in another browser profile or on another device. Wordshift is open source under the MIT License.
