  How to start
  Sign up with email or Google — 30 seconds, one time. After signing in, SwiftIn works on any website.
  
  Web page translation
  Translate entire sites into your language in one click, right in the browser. Launch — SwiftIn button on the side of the screen or hotkey Alt+S. Bilingual mode shows the original and the translation side by side — ideal for reading news, learning a language, or working with foreign documentation. Translation-only mode is for fast comprehension. Smart adaptation preserves the layout of popular destinations — Wikipedia articles, Reddit threads, GitHub, the X feed.
  
  Selection translation
  Select any text fragment on the page — a popup with translation and pronunciation of both original and translation appears next to it. The popup can be dragged, resized, and the translation copied with one click. Works on any website.
  
  Translate as you type
  Write text in any input field — in social media, messengers, mail clients, or contact forms. Click the translate button next to the field or use hotkey Alt+I — SwiftIn replaces your text with the translation.
  
  Three translation styles
  Every message needs its own tone. For example, depending on the style, the same source sentence can be translated three ways:
  ► Normal: "I'm not sure that's a good idea"
  ► Slang: "Hmm, kind of a sketchy plan"
  ► Business: "I have some reservations about this approach"
  Styles are available for translate-as-you-type and selection translation, with intensity control from light correction to full rewrite.
  
  AI voice
  Listen to translations in 70+ languages with realistic AI voice. Male and female voices available. Helps you learn correct pronunciation and pick up a new language faster. Voice works for selected text and for entries in your translation history.
  
  Unlimited translation
  SwiftIn pairs unlimited basic translation engines with a monthly AI-token quota. When the AI quota is exhausted, translation continues automatically through the basic engines — you are never blocked.
  
  Privacy
  ► Translation history is stored locally on your device by default. Server sync — only by explicit opt-in on Pro and Team plans.
  ► Your texts are not used for training AI models.
  ► No ads, no tracking. Texts are sent only to AI providers for generating the translation — the full provider list with locations is in the Privacy Policy.
  ► GDPR compliant. AI-processing details — in the Privacy Policy.
  
  Keyboard shortcuts
  ► Alt+S — translate the page or restore the original
  ► Alt+I — translate the active input field
  ► All shortcuts can be customized to your preference
  
  Customization
  ► Pin your favorite languages or use automatic detection
  ► Disable SwiftIn on specific websites
  ► Light, dark, and system themes
  
  Coming soon
  Actively in development: image translation (OCR), PDF document translation, video subtitles for streaming platforms, and a custom glossary for terminology control.
  
  Install free. Sign-up takes about 30 seconds with email or Google. Open any site and click the SwiftIn button or press Alt+S. Questions and feedback — [email protected].
