Immersive Translate
Immersive Translate is a bilingual AI translation extension and mobile app from Funstory.ai that renders a translation directly beneath the original text on any page. It translates websites, PDFs and e-books with the layout preserved, adds dual subtitles to YouTube, Netflix and 100+ video platforms, translates images and manga, and switches between DeepL, OpenAI, DeepSeek, Gemini and a dozen more engines.
What is Immersive Translate?
Immersive Translate is an AI-powered bilingual translation tool that lives where you read: as a browser extension on Chrome, Edge, Firefox and Safari, as a userscript and a manual ZIP install, and as a native app on iOS and Android. Instead of sending you to a separate translator page, it prints the translation directly below the original text and keeps both languages on screen at once, a side-by-side vertical layout the company says it pioneered for web translation. That single interaction is what the product is built around, applied consistently across pages, documents, subtitles and images.
The reach is unusually wide for a browser tool. On the web it translates static and dynamic pages, single-page applications and text inside input boxes. On documents it accepts PDF, ePub, HTML, TXT, DOCX, Markdown and subtitle files, produces either bilingual or translation-only output with the original formatting preserved, runs OCR on scanned PDFs, and adds BabelDOC layout-preserving PDF translation and PDF Pro for up to 1,000 pages a month. On video it renders dual subtitles in real time across more than a hundred platforms including YouTube, Netflix and Prime Video, generates subtitles for videos that have none, exports YouTube subtitles, and translates YouTube live streams. On images it reads text with OCR and re-renders it with inpainting so the original look is kept, as it is for comic and manga pages. Online meetings on Zoom, Google Meet and Microsoft Teams are translated in real time as well.
Under the hood the product is a router rather than a single model. It ships with over twenty translation engines and services, including DeepL, OpenAI, Gemini, Claude, DeepSeek, Microsoft, Google, Tencent Hunyuan, Volcengine, Youdao, Baidu and SiliconFlow, and covers more than a hundred language pairs. You choose the engine, the style of the bilingual output and the shortcuts; the extension remembers those choices per site. Context-aware translation with customizable AI terminology libraries lets you define domain glossaries so a medical or legal term is translated the same way every time.
There are also the smaller conveniences that make the tool sticky: select any word or phrase to see a translation with pronunciation, hover a paragraph and press a shortcut for an inline gloss, or type into any web input box and hit the spacebar three times to translate what you wrote. Settings and glossaries sync to the cloud, and one account covers up to eight devices at once.
Privacy is marketed as a first-class feature. Immersive Translate states that translated content is not retained, that your text is never used to train models by the company or any third party, and that requests are encrypted in transit, with ISO 27001, ISO 27701, GDPR and APPI compliance badges on the pricing page. The company behind it is Funstory.ai Limited, based in Hong Kong, and support runs through support@immersivetranslate.com. The service claims thirty million users and is a 2024 Chrome Favorite, an Edge Editors' pick, a Safari Top 10 extension and a Firefox recommended extension.
Immersive Translate Core Features
Side-by-side bilingual page translation
the translation is rendered directly beneath the original paragraph on any site, including single-page apps and dynamic pages, so nothing is lost in a separate translator tab.
Layout-preserving document translation
PDF, ePub, DOCX, HTML, TXT, Markdown and subtitle files come back with formatting, figures and captions intact, with OCR for scanned PDFs and BabelDOC layout preservation.
Dual video subtitles on 100+ platforms
live bilingual subtitles for YouTube, Netflix and Prime Video, plus AI-generated subtitles for videos that ship without any captions and YouTube live-stream translation.
Image, manga and comic translation
OCR reads the text and inpainting re-renders it in place, so screenshots, web images and manga pages keep their original look; Pro and Max include 3,000 images a month.
Twenty-plus engines and 100+ language pairs
DeepL, OpenAI, Claude, Gemini, DeepSeek, Microsoft, Google, Youdao, Baidu, Hunyuan and more, selectable per site with context-aware custom terminology libraries.
Quick reading tools on any page
select text for an instant translation with pronunciation, hover a paragraph for an inline gloss, and triple-tap the spacebar in any input box to translate what you typed.
Meeting translation and subtitle export
real-time translation on Zoom, Google Meet and Microsoft Teams, YouTube subtitle export, and cloud sync that carries your settings and glossaries between devices.
Privacy and compliance by design
no retention of translated content, no use of your text for model training, encrypted transmission, ISO 27001 and ISO 27701 certification with GDPR and APPI alignment.
Who is Immersive Translate for?
Students and self-directed learners are the most obvious audience. Immersive Translate was built around bilingual reading rather than plain machine output, so an English journal article, an application essay draft or a multilingual textbook stays readable in the original while the translation sits directly underneath each paragraph. The site's own learning page points at application essays, paper citations and TOEFL vocabulary, and the study workflow of comparing your own wording with the source sentence is exactly what a side-by-side layout is good for. Researchers, clinicians and analysts are the second core group. Anyone who has to read a 40-page PDF for one useful table gets a layout-preserving bilingual document with the formatting, figures and captions still in place, plus OCR handling for scanned papers and support for ePub, DOCX, HTML, Markdown and subtitle files. Technical research briefs, LLM reports, medical literature and contracts all fall into the same workflow, and the copy is explicit that academic and financial material is the target. Cross-border professionals read vendor documentation, forums, dashboards and untranslated web apps all day. Because the extension edits the live DOM rather than shipping the page to a separate translator tab, it handles single-page applications, dynamic content and logged-in interfaces that simpler page-translator tools struggle with, and meeting translation covers Zoom, Google Meet and Microsoft Teams for calls where nobody shares a language. Content creators and fan translators use it to reach a global audience: dual subtitles and subtitle export for video, batch comic and manga translation for chapters that never get an official release, image translation for screenshots and thumbnails, and video translation for content that has no captions to begin with. Language learners of every kind are served by the quick-translation tools rather than by documents alone: select a word or phrase for an instant translation with pronunciation, hover and press a shortcut for a paragraph gloss, or type into any web input box and translate it in place. None of that requires leaving the page, which is the point of the product's name. Finally, teams and organisations get a separate Business plan with seat management and a shared glossary, and an Enterprise plan for 500+ seats or private deployment, so translation can be rolled out across a company instead of one browser at a time.
Immersive Translate Use Cases
Read a 40-page foreign-language research paper or medical report as a bilingual PDF that keeps its layout, with OCR covering the scanned appendix.
Watch YouTube, Netflix or Prime Video with dual subtitles, including videos that never had captions, and export the subtitle track for reuse.

Use untranslated web apps, forums, Steam pages and AO3 in your own language without leaving the page or losing the original wording.
Follow cross-language online meetings on Zoom, Google Meet and Microsoft Teams in real time, so nobody has to summarize afterwards.
Study abroad: polish an application essay, check paper citations and build TOEFL vocabulary against the original English source.
Repurpose content for global audiences by translating videos, images, e-books and articles, then exporting bilingual subtitles for publishing.
Work through contracts, vendor documentation and financial filings as bilingual documents where the exact source wording stays visible for review.
Immersive Translate Pros and Cons
Pros
- The free tier really is usable: unlimited web page, PDF and YouTube bilingual subtitle translation on general models, with no credit card and only fair-use request limits.
- Bilingual side-by-side output across web pages, layout-preserved PDFs and video subtitles is the best reading experience in this category, and the 100+ language pairs and 20+ engines leave nothing to hunt for.
- One subscription covers a lot of ground that competitors sell separately: image and manga OCR translation, meeting translation, e-book translation, subtitle export and cloud sync across up to eight devices.
- Privacy claims are unusually concrete: no retention, no model training on your content, encrypted transmission, and ISO 27001 / ISO 27701 certification with GDPR and APPI alignment.
- Cross-platform coverage is broad and current: Chrome, Edge, Firefox, macOS Safari, a userscript and a manual ZIP install, plus iOS and Android apps.
Cons
- The free tier's daily request limit is never given a number, so you only discover the fair-use ceiling when you hit it, and the strongest engines are effectively reserved for paying users.
- Paid tiers meter the good models: Pro gets 20 million advanced tokens a month and Max only 2 million top-tier tokens plus 50 million advanced, which heavy readers of Claude or GPT-class engines can exhaust.
- Pricing is promotion-driven and quote-only for teams: the headline $6.99 and $13.99 months are a limited-time 50 percent campaign, the second year renews at $119.88 and $239.88, and Business and Enterprise plans publish no numbers at all.
