SMALL TOOL. THOUGHTFUL DETAILS.

Your text, on your terms.

Case that makes sense.

Turn “Teh” into “The” and “TEH” into “THE”. Match whole words, respect case, or use regex for advanced rules.

Keep the good formatting.

Keep bold, italics, and links around replaced text. Or switch to plain text for a clean start.

The right rule, in the right place.

Use rules on every site or limit them to specific domains. Pause any rule — or the whole extension — whenever you want.

Your rules, easy to manage.

Edit rules inline, try sample text, and import or export JSON backups. Start a new rule from selected text with a right-click.

A FEW GOOD QUESTIONS

Before you copy.

How do I install SwapText in Brave or Opera?

Brave can install SwapText from the Chrome Web Store using the button below. Opera will use its own store listing as soon as that release is approved. Chrome, Firefox and Edge have been tested on macOS; Brave and Opera compatibility has not yet been independently tested.

Are replacement rules included?

No. Start with an empty rule list and add your own words and phrases. The examples on this website are only a demonstration.

Does it work outside the browser?

Yes, for text copied from a supported webpage. SwapText changes the clipboard at copy time, so corrected text can be pasted into native apps on Windows, macOS, or Linux. It does not change text copied from other apps.

Does it work on every website?

Browser settings pages, extension stores, and other protected pages do not allow content scripts. Some custom editors, including sites with their own clipboard handling, may bypass replacements. You must also allow the extension access to the site.

What happens to bold text and links?

With Preserve formatting on, replacements happen inside individual text nodes while surrounding markup is preserved. A phrase split across formatting boundaries is not replaced in that mode. The app receiving the paste also determines which formatting is retained.

Can I use languages other than English?

Yes. Your rules can contain words and phrases in other languages. The interface is in English, and whole-word matching supports Unicode letters.

Can I switch it off?

Yes. Pause all replacements from the toolbar popup, or disable individual rules in the options page. Your saved rules remain available.
