SwiftIn — AI translator for web pages and what you Autor: SwiftIn

Communicate without borders, learn the language, smart translation

SwiftIn — AI translator for web pages in 100+ languages. Read any site in your language, write in yours — send in theirs. Bilingual mode helps you read foreign sites and learn the language at the same time. Works on any website.

Web Page Translation
► Bilingual mode: original and translation displayed side by side without breaking the site's design. Perfect for immersive reading of foreign content and language learning.
► Smart adaptation for popular sites: Wikipedia, Reddit, GitHub, X (Twitter), news portals. Layout is preserved — no broken design.
► Translation-only mode: for fast comprehension when the original is not needed.
► One-click launch: SwiftIn button on the side of the screen or Alt+S hotkey.

Translate As You Type
► Write in your language — send in theirs: type into any input field (social network, messenger, mail, form). Press Alt+I or the translate button — SwiftIn replaces your text with the translation in the target language.
► Three writing styles: Normal, Slang, Business — with intensity control from light correction to full rewrite. Match the tone to the context.
► Universal: works in any text field on any website.

Selection Translation
► Highlight — get a translation: popup with translation and pronunciation of both original and translation. Draggable, resizable, copyable with one click.
► Works on any website.

Language Learning
► Bilingual mode as a natural language course: regular reading helps you pick up the language on your favorite sites — without textbooks or apps.
► Pronunciation of both original and translation: text-to-speech available for both languages on selected text for proper pronunciation practice.
► AI text-to-speech in 70+ languages: male and female voices. Helps you remember how words sound in context.

Three Translation Styles
Every message needs its own tone. For example, the same English sentence "I'm not sure that's a good idea" translates differently depending on the style:
► 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.

Smart Context
► Page title and summary are passed as context — more accurate terminology, better idioms.
► 10+ AI engines to choose from, including Gemini, GPT, Claude and Grok: if one provider is blocked or down, switch to another in one click.

Free Plan
► 100,000 AI tokens every month + unlimited basic translation.
