Why Confidential Translator?

Most translation services send your documents to external servers. Confidential Translator runs entirely on your machine — no internet required, no data leakage possible. Perfect for legal documents, medical records, financial reports, and any sensitive content.

Core Features

  • Total Privacy

    Runs completely offline on your local machine. Your sensitive documents never leave your computer.

  • Local LLMs

    Powered by state-of-the-art local models like Qwen 3 (via Ollama) for high-quality, nuanced translations.

  • File Format Support

    Translates PDF, Word, Markdown, Excel, CSV, and Images (OCR). Export back to the original format.

  • Multi-Lingual + Custom

    Built-in support for English, Chinese, German, French — plus custom language input with AI validation.

  • Dashboard & Analytics

    Track translation history, processing speed (tokens/sec), and detailed per-translation reports.

  • Stunning Glassmorphism UI

    Modern Vue 3 interface with fluid animations, dark mode, real-time streaming, and i18n support.
