YabaiLingo - Learn Japanese

Learn the Japanese people actually speak — casual speech, slang, and the register switching textbooks skip. YabaiLingo is a serious spaced repetition (SRS) app for Japanese vocabulary, built around real sentences instead of isolated words.

SMART FLASHCARDS (SRS)
• 3,800+ words, every one with example sentences and native-quality audio
• Modern FSRS spaced repetition scheduling — each card comes back right before you'd forget it
• Three review modes: recognition (read it), recall (produce it), and listening (hear it)
• No sessions or daily lesson gates — open the app, review what's due, done
• Undo button for fat-finger answers

SENTENCE MINING
• Found a word in an anime, manga, or conversation? Add it to your deck with your own example sentence
• Search the built-in dictionary or create fully custom cards
• Mined words get the same SRS scheduling as everything else

READING MODE
• Paste any Japanese text — an article, a tweet, song lyrics
• Every word becomes tappable, colour-coded by whether you know it
• See what percentage of the text you can read
• Tap an unknown word to see its meaning and add it to your deck with its sentence attached

STORIES WITH FULL AUDIO
• Voiced, chat-style stories in natural casual Japanese
• Tap any word for an instant gloss, Duolingo-style
• Comprehension questions test what characters actually said
• Illustrated picture stories with end-of-story quizzes

KANA, KANJI & RADICALS
• Kana practice with mastery tracking
• Kanji broken into 80 radicals across 4 tiers, so characters stop looking like random strokes
• Kanji writing and context practice
• Browse vocabulary by situation — at the izakaya, arguing, texting — not just JLPT level

REAL JAPANESE, YOUR CHOICE
Japanese has rough pronouns, contractions, and slang you'll hear in the first five minutes of any anime. YabaiLingo teaches them, with register notes so you know what's safe to say to your boss. Prefer to keep it clean? Toggle explicit content off any time.
