About

Lexi Scan

Features
Read full description

Most flashcard apps make you type every card. Lexi Scan makes them for you. Take a photo of a page, or paste a paragraph in any language. Gemini AI instantly finds the words you don't know yet, filtered to your CEFR level (A1 to C2), translates each one, and turns it into a flashcard, including audio to learn how to pronounce new words. No typing, no copy-paste. Then study the smart way: Lexi Scan schedules every card with spaced repetition (the SM-2 algorithm used by Anki), so each word comes back right before you'd forget it. Rate Again / Hard / Good / Easy and let the app do the scheduling. WHY LEXI SCAN • Scan, don't type: turn any paragraph or photo into cards in seconds • Level-aware AI: pulls only words at the level you pick, not ones you already know • Auto-translation built in: every new word arrives with its meaning • Anki-style spaced repetition for real long-term memory • Premade starter decks for Swedish, Chinese, Spanish, and more • Tap any card to hear native pronunciation • Daily goals, streaks, and optional reminders to keep you going YOUR KEY, YOUR DATA Lexi Scan runs on your own free Google Gemini API key. No subscription, no scan limits, and your decks never leave your device. The free Gemini key takes about 2 minutes to set up, and the app walks you through it.
