HyTranslate: Offline Translate

Private offline AI translation for text, PDFs, Markdown and local files.

HyTranslate is a private AI translation app built for people who need translation without sending local text or files to a cloud translation server.

Translate text on your Android device, even in airplane mode. The local translation model is bundled with the app, so your typed text and supported local documents stay on your phone.

Key features:

- Offline AI text translation powered by an on-device model
- Auto-detect source language and translate across 30+ languages
- Local TXT, Markdown, and text-based PDF translation tasks
- Web link translation that fetches only the URL you choose, then translates locally
- Translation history stored on your device
- Favorites, style presets, and terminology glossary with HyTranslate Pro
- No account or registration required
- No analytics or telemetry in this build

Document translation:

Create long-running tasks for TXT, Markdown, basic text-based PDF files, and webpage links. Local documents are processed on this device. Text-based PDFs can be translated into readable output; scanned or image-only PDFs require OCR and may not be supported.

Privacy:

HyTranslate is designed for local-first translation. Typed text, local documents, task records, settings, glossary entries, and history are stored locally on your device. Web link translation uses network access only to fetch the webpage URL that you enter.

Free and Pro:

The free tier includes selected common language pairs. HyTranslate Pro unlocks broader language access, translation styles, custom glossary terms, unlimited history, and favorites.

Important notes:

- Translation quality depends on language pair, device memory, and document structure.
- The app is larger than typical translator apps because the local AI model is bundled for offline use.
- Web link tasks are not fully offline because they need network access to fetch the selected page.
