Janus is an open-source Android app that provides contextual word and concept translations by leveraging the vast, human-curated knowledge graph of Wikipedia.

Instead of literal machine translation, it finds the corresponding Wikipedia article in the target language to offer a more accurate and context-aware translation.

Main Features

• Contextual Translation: Uses Wikipedia article titles for accurate, context-aware translations instead of literal machine translation.
• Multi-Language Support: Translate from any Wikipedia-supported language to any other, with support for multiple target languages.
• Rich Information: Displays short descriptions and article summaries with HTML formatting for enhanced context.
• Smooth Animations: A guiding icon seamlessly transitions through the translation workflow, providing visual continuity and progress indication.
• Full History & Bookmarks: Keeps a chronological log of all translations and allows you to save important ones to a dedicated bookmarks screen.
• Searchable History: Quickly find past translations with real-time filtering in the history screen.
• Quick Actions: Copy translations to clipboard and open Wikipedia articles directly from the app.
• Modern UI: A clean, intuitive interface built with Jetpack Compose, supporting both light and dark themes.
