Quick start
Install. Translate.
No account. No setup. No captcha. Install the extension — and SwiftIn works on every page on the web.
Translate a whole page
On any foreign-language site, page translation works in two modes. Translation only (default) replaces the original with the translation — fast reading. Bilingual shows original and translation side by side — great for reading articles or learning the language.
Translate just the part you need
Highlight any text on the page — the translation pops up in an instant. The same popup also has the speaker for audio, an engine picker, and translation styles.
Translate as you type
Writing a reply in your language? Trigger input translation — your text gets replaced with the translation in the recipient's language. Works in any text input on the web.
