Traductor

Read EPUB and PDF in any of eleven languages. Tap a word to translate. Save it. Watch your dictionary grow into the words you actually look up.

Coming soon to the App Store for iOS 18+.

What it does

• Tap any word for an instant translation. Powered on-device by Apple’s Translation framework. Works offline once the language pair is downloaded.
• Save what’s worth keeping. Your personal dictionary lives in the app, with notes, definitions, mastery, and the source sentence you saw the word in.
• Underline what you’re learning. Saved words gently underline in the reader, with the colour fading as your mastery grows. The chrome stays out of your way.
• Bring your own dictionaries. URL-template links open in an in-app browser sheet — Wiktionary, Linguee, Le Robert, Larousse, Duden, RAE, dict.cc, whatever you read in.
• Two reading themes, adjustable type, bookmarks, per-book reading position remembered.
• Import EPUB and text-PDF from Files, Mail attachments, or any app’s Share Sheet. Books stay on your device; nothing is uploaded.

Reader-side languages: English, French, German, Spanish, Italian, Portuguese, Dutch, Russian, Polish, Ukrainian, and Hindi.

Traductor is inspired by LUTE (Learning Using Texts) by Jeff Zohrab — an open-source self-hosted web app that pioneered the “learn a language by reading and tapping words” workflow on desktop. Traductor is an independent iOS reimagining of the same idea, written from scratch in Swift; no LUTE source code is used. LUTE is MIT-licensed.
