Janus

Contextual translations using Wikipedia's knowledge graph.

New in version 0.1.6

Welcome to Janus v0.1.6 (11)
* Introduced an open-source language-detection engine in addition to the local-I-backed.
* Improved reliability of automatic language detection with a new fallback mechanism.
* Regular updates to the supported languages list.

Janus 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.

Features:
* Contextual Translation: Uses Wikipedia article titles for accurate, context-aware translations.
* Multi-Language Support: Translate from any Wikipedia-supported language to any other.
* Rich Information: Displays short descriptions and article summaries.
* Full History & Bookmarks: Keeps a log of translations and allows saving important ones.
* Searchable History: Quickly find past translations.
* Quick Actions: Copy translations and open Wikipedia articles.
* Modern UI: Clean interface supporting light and dark themes.
