Immersive Translate

What is Immersive Translate?

Immersive Translate is a browser extension and app that translates web pages, documents and videos while keeping the original text visible alongside the translation. Instead of replacing a page with one language, it places each translated paragraph next to its source, which helps readers check meaning and learn vocabulary as they go. The same bilingual layout extends to PDFs, ePub and DOCX files, subtitles on YouTube and Netflix, manga and images through OCR, and text you type into input boxes.

Immersive Translate is developed by Funstory.ai Limited, which its site places in Hong Kong. The company claims more than 30 million users, while the Chrome Web Store listing showed 3 million Chrome users, a 4.0 rating from about 3,100 reviews and an update on 25 September 2026. It works with more than 20 translation engines, including ChatGPT, DeepL, DeepSeek, Gemini and Claude, and offers a free tier alongside Pro and Max memberships.

Key Features

• Bilingual web page translation: Immersive Translate shows each translated paragraph beside the original rather than replacing the page. Its content detection targets main article text, so menus and clutter are less likely to be translated needlessly.
• Document translation with BabelDOC: Immersive Translate translates PDF, ePub, DOCX and Markdown files while preserving layout, and adds OCR for scanned files. Its BabelDOC service and App Store listing mention formula and table recognition for academic papers.
• Bilingual video subtitles: Immersive Translate adds dual-language subtitles on more than 100 video platforms, including YouTube, Netflix and Prime Video. The Chrome listing also mentions real-time subtitle support for Zoom, Google Meet and Teams.
• Image and manga translation: Immersive Translate reads text in images, manga, webtoons and comics with OCR, then redraws the translation over the original. That helps readers follow untranslated comics and screenshots.
• Hover, selection and input box tools: Immersive Translate translates a paragraph on hover, any selected text, or what you type after pressing the space bar three times. The input box feature helps you reply in another language on forums or chat.
• Choice of 20+ engines: Immersive Translate connects to more than 20 translation services, including DeepL, OpenAI, Claude, Gemini and DeepSeek. You can switch engines per task or add your own API keys for some services.
• Glossaries and expert roles: Immersive Translate supports custom terminology libraries and industry-specific AI expert roles for context-aware output. Technical, legal or academic readers can keep key terms consistent across long documents.
• Cross-platform availability: Immersive Translate runs on Chrome, Edge, Firefox and Safari, plus iOS and Android apps and a userscript version. Your reading setup can follow you from desktop browser to phone.

Pros

• Original stays visible: Immersive Translate keeps the source text next to the translation, which makes errors easier to spot. Trancy’s 2026 comparison calls it a strong reading tool for professionals handling foreign-language content at scale.
• Generous free tier: Immersive Translate offers free high-quality translation with a reasonable daily request limit, according to its pricing FAQ. Casual readers can use the core web page features without paying or registering.
• Wide format coverage: Immersive Translate handles web pages, PDFs, ebooks, subtitles, images and manga in one extension. That single install replaces several single-purpose tools for students, researchers and anyone who reads widely online.
• Engine flexibility: Immersive Translate lets you pick from more than 20 engines rather than locking you into one model. You can compare DeepL and an LLM on the same text and keep the one that reads better.
• Large user base: Immersive Translate reports more than 30 million users, and its Chrome extension alone lists 3 million. Frequent updates, the latest on 25 September 2026, suggest active development.
• Stated privacy controls: Immersive Translate says content is not used to train AI models and that requests are encrypted in transit. Its Chrome listing also claims zero content retention, which matters for confidential documents.

Cons

• Mixed Chrome Store rating: Immersive Translate holds a 4.0 rating from about 3,100 Chrome Web Store reviews, lower than its 4.6 App Store score. Some users clearly hit problems, so test it on your usual sites first.
• Premium models cost extra: Immersive Translate reserves premium engines and higher quotas for Pro and Max memberships. Max costs $34.99 a month on the App Store, which is a large jump from the $9.99 Pro tier.
• Trial renews automatically: Immersive Translate charges your account when a free trial ends unless you cancel beforehand, according to its pricing FAQ. Set a reminder if you only want to test the paid features.
• No learning tools: Immersive Translate does not include vocabulary saving, flashcards, grammar analysis or speaking practice, Trancy’s comparison notes. Language learners may need a separate study app alongside it.
• Accuracy depends on engine: Immersive Translate’s output quality varies with the engine you select and the subject matter. Machine translations of legal, medical or technical material still need checking by a fluent reader.

Who is Using Immersive Translate?

• Researchers and students: read foreign-language papers and translate PDFs with formulas and tables intact.
• Language learners: compare original and translated text side by side on articles and videos.
• Professionals: follow international news, documentation and meetings with bilingual subtitles.
• Manga and video fans: read untranslated comics and watch foreign shows with dual subtitles.

Pricing

Immersive Translate is free for basic use, with Pro at $9.99 a month and Max at $34.99 a month (App Store in-app prices, October 2026).

The official pricing page did not display plan figures when checked, so these prices come from the developer’s App Store listing and match Trancy’s 2026 comparison. AlternativeTo quotes $9 to $17 a month, which looks out of date. Regional prices and in-browser checkout can differ, so confirm the amount shown at checkout before you subscribe.

What Makes Immersive Translate Unique?

Side-by-side bilingual output is the core of Immersive Translate’s approach. Most translators swap the page into a new language, whereas this extension inserts each translation under its source paragraph and applies the same idea to PDFs, subtitles and manga. Pairing that layout with a choice of more than 20 engines lets you match the model to the material, which suits readers who want to understand and check a translation rather than simply replace the original.

Compatibilities and Integrations

• Browsers: Chrome, Edge, Firefox and Safari extensions, plus a userscript version.
• Mobile: iOS app on the App Store and Android app on Google Play or as an APK.
• Translation engines: More than 20 services, including DeepL, OpenAI, Claude, Gemini and DeepSeek.
• File formats: PDF, ePub, DOCX, Markdown, TXT and ASS or SRT subtitle files.

How We Rated It

Summary

Immersive Translate suits students, researchers and professionals who read a lot of foreign-language web pages, papers and videos. Its main limitation is that the best engines and higher limits sit behind Pro or Max memberships, and Chrome Web Store reviews are mixed. We think the free tier is enough for most casual reading. Before paying, test the PDF translator on one of your own documents, since layout handling is the feature most likely to justify Pro.
