OpenImmersive Translator by Nolan Bryant

OpenImmersive Translator is an open-source (AGPL-3.0), privacy-first bilingual webpage translator.

🔒 Privacy by architecture, not by promise
- No middle server: requests go straight from your browser to the engine you choose
- History and settings never leave your browser
- Fully open source and auditable

🌐 Bilingual or translation-only, in place
- Side-by-side translation on the page you are reading (or show translation only) — no copy-paste, no uploads
- Toggle with Alt+T / Alt+A; Alt+W re-translates dynamic content
- Selection popup, Alt+hover per-paragraph translation, Alt+Enter to translate what you type
- 199 languages, all verified working

📄 Subtitle & document files
- Translate srt / ass / txt / md / html locally, keeping timelines and formatting
- A full movie's subtitles finish in about half a minute

🛡 Sensitive-data masking (Beta — rare in this category)
When enabled, emails, phone numbers, card numbers, national IDs and API keys are replaced with placeholders locally before translation and restored locally after. Originals never leave your browser.
