## Description

Immersive Translate Ultra is a cutting-edge Chrome extension designed to provide an immersive bilingual translation experience for web pages. It intelligently identifies the main content areas, displaying both original text and translation side-by-side by paragraph to enhance readability. Unlike generic translators, it avoids translating irrelevant areas of the page, similar to browser immersive reading modes.

This extension supports over 10 major translation services including Deepl, Google, Bing, Tencent, Youdao, and others. It is optimized for popular sites such as Twitter, Reddit, Gmail, YouTube, and Telegram for a superior translation experience. Advanced features include customizable paragraph length, bilingual PDF translations, and foreign e-book reading compatibility via EPUB online readers. Privacy-conscious users can rest assured as no personal data is collected, though content is sent to third-party translation APIs for processing.

## Review summary

Users commonly report the add-on works well and outperforms some alternatives, but multiple reviewers cite subtitle/language-handling bugs, translation failures on certain sites, and regressions after updates. Several users also complain about paywalled features and request more free functionality.

### Pros

- Reliable/effective in many cases — multiple users said it works perfectly or is the best they found
- Performs better than some popular alternatives (one reviewer switched from a widely-used add-on that failed)
- Generally liked by several users who left simple positive reviews ('good','works well')

### Cons

- Subtitle and language-handling problems — forced wrong subtitle language for some users and exported bilingual subtitles were merged/changed after an update
- Translation failures on some sites or inputs (e.g., failed Japanese romaji → English; translation engines appeared to change text but not produce proper translations)
- Too many paid/locked features; users request more free functionality
- Updates have introduced regressions or negative changes (slower performance, changed export behavior)
