Shiberu: Learn From Your Shows

Shiberu turns the shows you watch into flashcards — and puts a full spaced-repetition reviewer on your phone. MINE FROM WHAT YOU WATCH With the free Shiberu browser extension for Chrome and Firefox, click any subtitle word on YouTube, Netflix, Crunchyroll, Viki, Bilibili, or any HTML5 video. You can also load your own .srt, .ass, or .vtt subtitle files. Shiberu automatically fills in the reading, meaning, sentence, and audio. Save the card, and it will be waiting in the app for your next review. A FULL FLASHCARD REVIEWER • FSRS-6, the modern spaced-repetition scheduler • Deck option presets, :: subdecks, a card browser, and custom study • Timers, auto-advance, and Again / Hard / Good / Easy ratings • Create your own note types and card templates, with images and audio STUDY OFFLINE Download a deck once and review it without an internet connection — on the subway, on a plane, or anywhere else. Your progress automatically syncs when you're back online. BRING YOUR DECKS • Import .apkg decks with their full review history. Shiberu replays every review through FSRS, so your cards stay on schedule instead of starting over. • Export any deck back to .apkg at any time. No lock-in. • Study on your computer too. Link your decks with the free Shiberu Sync add-on for desktop Anki (25.07 or later), and everything stays in sync both ways — reviews, due dates, deck option presets, note edits, and media. SHARE DECKS Share a deck with your friends or publish it for every learner. Subdecks are included, so anyone who adds your deck gets the complete subdeck tree with every card. LANGUAGES Japanese, Korean, and Chinese get full readings and dictionaries. For other languages, Shiberu provides AI-powered explanations of words in context. READ, NOT JUST REVIEW The Reader lets you study directly from texts you paste or import, including: • EPUB • PDF • Word • HTML • Markdown • Plain text • Subtitle files You can also start with built-in graded stories for Japanese, Korean, and Chinese. Tap any word to look it up and instantly turn it into a flashcard. STAY ON TRACK • Review Buddy — a home-screen widget that shows what's due and notices when you skip a day • Study reminders and streaks • A vocabulary garden that grows as you learn • Forest, Light, and Dark themes • Interface available in English, 한국어, 日本語, Español, 简体中文, and 繁體中文 NO SUBSCRIPTION.
