Your words, beautifully translated
Dian is a dictionary app that translates words and phrases across multiple languages at once — with hotkeys, auto-complete, and a clean, distraction-free interface.
Translate faster, learn deeper
Built for language learners and polyglots. Dian stays out of your way so you can focus on words that matter.
Instant search & autocomplete
Start typing and Dian suggests words in real-time. Press Ctrl+F to jump straight to the search bar.
Multi-language at once
Translate a word into all your configured languages simultaneously. No more tab-switching between dictionaries.
Keyboard-first workflow
Navigate with J/K, minimize with Esc, and switch languages inline with /en, /zh, /fr.
Export your word lists
Save and export vocabulary to CSV. Import into Quizlet, Anki, or any flashcard app for spaced repetition practice.
Text-to-speech pronunciation
Hear how words sound in any language with built-in Google TTS. Perfect your accent as you learn.
Clean, focused design
No clutter, no ads. Dian's interface disappears so your words take center stage. Customize detail links for every language.
Simple, fast, intentional
Two steps from setup to fluency. Configure your languages once, then translate everything.
Configure your languages
Pick the languages you know and the ones you're learning. Set custom detail links for deeper lookups.
