Point your camera at any foreign word — a menu, a subtitle, a screenshot — and Lucideck turns it into a flashcard, translated and ready to study
Every word you almost learned.
Language learning app screenshots. Subtitles you paused on. Phrases from that café menu. Words you looked up twice. It all goes somewhere — notes, screenshots, the back of your mind — and then it disappears.
Lucideck closes the gap. Scan any foreign text, get a flashcard, and let spaced repetition do the rest. The vocabulary you actually encounter, actually remembered.
HOW IT WORKS
1. Scan — Point your camera at text, or import from your photo library. Lucideck reads the language, pulls the phrase, and pairs it with a translation automatically.
2. Review — Cards come back at exactly the right moment using spaced repetition (the same science behind Anki). Easy cards appear less often. Hard ones return sooner.
3. Remember — Not a passive translation app. Lucideck builds retention through active recall — the method proven to work for long-term language memory.
BUILT FOR HOW YOU ACTUALLY LEARN
Most language learners don't study in a vacuum. They watch shows, read posts, travel, sit in classes — and collect vocabulary as they go. Lucideck is the system that captures it all.
• Scan any text — screenshots, photos, printed pages, menus, subtitles
• Automatic translation across 63 languages
• On-device text recognition — no internet required to scan
• Spaced repetition scheduling keeps your deck from growing out of control
• Organize by deck — French café vocab separate from Japanese anime phrases
• Pronunciation audio on every card
• Clean, distraction-free interface designed for actual focus
WHO IT'S FOR
— The language learner who pauses shows constantly to look things up
— The structured learner who wants real-world vocabulary alongside their daily lessons
— The traveler who photographed every sign and menu abroad and never studied them
— Anyone with a folder of "I'll study this later" screenshots that never gets studied
SUPPORTED LANGUAGES
63 languages with automatic detection, including French, Spanish, German, Italian, Portuguese, Japanese, Korean, Chinese (Simplified), Russian, Arabic, Dutch, Polish, Swedish, Norwegian, Danish, Finnish, Turkish, Hindi, Thai, Vietnamese, Indonesian, Czech, Hungarian, Romanian, Ukrainian, Greek, Hebrew, and more.
PRIVACY FIRST
Text recognition runs entirely on your device. Your flashcards are stored locally and never leave your phone. No account required to get started.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
AutoScan "Save without reviewing" now shows a deck picker (ActionSheetIOS) — pick from existing decks directly; creating a new deck instead prompts to upgrade, and choosing to upgrade advances to the paywall
CardPreview tap-to-flip now works (wrapped in TouchableOpacity)
Bilingual single-scan fix — stripNativeLines now also runs on the single-scan path (was batch-only before), fixing Duolingo-style screenshots that showed both languages on the card front
AutoScan ~2x faster — ML Kit now processes 4 images concurrently instead of sequentially
ProGateModal — new reusable styled paywall modal ("Upgrade to Pro" / "Go Back") replaces all the old Alert-based prompts across AutoScan, Decks, BatchResults, SaveToDeck
Case-insensitive deck name uniqueness enforced everywhere a deck can be created
Translation chunking — long text now splits into ≤1000-char chunks before sending to the gtx endpoint, preventing URL truncation on long scans
