## What it is
Immersive Translate is a bilingual translation tool that displays AI translations alongside original text on web pages, PDFs, EPUB ebooks, video subtitles, input boxes, and images, shipped as a browser extension for Chrome, Edge, Firefox, and Safari plus iOS/Android apps. It integrates 20+ translation engines such as DeepL, ChatGPT, DeepSeek, and Gemini; note that this GitHub repo only distributes release builds and tracks issues, since the product's source code is closed (the older open-source version was archived in 2023).

## Use cases
- translate foreign-language web pages into my language while keeping the original text visible
- read PDF documents with side-by-side bilingual translation that preserves layout
- get bilingual subtitles for YouTube and Netflix videos
- translate EPUB ebooks and TXT files
- translate text as I type it into input boxes
- translate selected text or paragraphs on mouse hover
- translate manga, comics, or images
- use ChatGPT or DeepL as the translation engine while browsing

## When to choose
- You want immersive bilingual reading of websites, PDFs, ebooks, or video subtitles inside your browser
- You want to pick among many AI translation engines (DeepL, OpenAI, Gemini, DeepSeek, etc.) within one tool
- You want a polished, widely adopted translator with 20M+ installs across major browsers and mobile platforms

## When to avoid
- You need open-source software you can inspect, self-host, or modify - the source is closed and the repo only ships release binaries
- You need fully offline translation with no cloud or AI service involved
- You need a library or API to embed translation into your own application rather than an end-user tool
