Overview
Japanese SRS flashcards with kanji lookup, YouTube & Netflix capture, and an optional RPG that rewards studying with kanji.
ボイド Study is a Japanese learning tool built for people who want to study from real content — not textbook sentences. 📖 Spaced Repetition Flashcards Study Japanese vocabulary using a proven SRS (spaced repetition) algorithm that schedules reviews at the right time. Built-in N5, N4, N3, N2, and N1 vocabulary decks to get you started immediately. 🎬 YouTube & Netflix Capture While watching Japanese content, a capture bar lets you save subtitle lines as flashcards with one click. Timestamps are saved so you can jump back to any moment. A sidebar shows all your captures from the current video in order. 🔍 Kanji Lookup Look up any kanji from the Reference tab or by right-clicking selected text on any page. See stroke count, on/kun readings, meaning, example words, and browse by radical. 🈳 Kana Reference Full hiragana and katakana charts with click-to-hear pronunciation. Pop out into a separate window so you can keep it visible while studying. 🤖 AI Explanations (optional) Add your own Anthropic API key to get AI-powered grammar explanations and contextual breakdowns of captured sentences. Your key is stored locally and requests go directly to Anthropic — nothing passes through our servers. ⚔️ ボイド Quest (optional) An auto-battle RPG hidden in the Extras menu. Defeat zone bosses to collect boss kanji. Every zone you clear adds +1 bonus coin to each study session — so playing the RPG makes studying more rewarding. 15 zones, 12 spells, gear system, and a full kanji collection book. 🪑 Toy Desk (optional) Spend coins earned from studying to pull for collectible toys in a gacha system. Decorate your desk with 21 unique animated toys. Everything stays on your device No account required. No servers. No tracking. All your cards, captures, and progress are stored locally in your browser. You can export a full backup at any time.
