--- Core Features ---

1. Multiple Input Methods
• Custom Kana Keyboard: A built-in keyboard that mirrors the Gojuon chart layout — what you see is what you type. No need to install a Japanese system keyboard.
• Handwriting Recognition: Write naturally on the canvas, and our ML model recognizes your strokes in real time.
• Image Recognition: Snap a photo of any kana you can't read — AI identifies it instantly.
• Speech Recognition: Practice pronunciation and see if AI understands you!

2. Offline AI Chatbot (On-Device AI)
• Privacy First: Powered by on-device large language models (choose and download open-source models). All processing stays on your device — works in airplane mode, zero data sent to the cloud.
• Chat Freely: Ask the AI any Japanese question, anytime, without internet — and without embarrassment.

3. Deep Kana Learning System
• Mnemonics & Etymology: Every kana includes vivid memory aids and its historical kanji origin (e.g., あ comes from 安).
• Animated Stroke Order: Watch standard stroke animations, then practice writing side-by-side.
• Vocabulary Cards: Each kana comes with common words. Let AI generate unlimited example words to reinforce your memory.

4. Reading & Listening Training
• Random Quiz Challenges: Flashcard-style quizzes with varied fonts (handwritten, Mincho, Gothic) to train real-world recognition — signs, menus, manga.
• Listening Mode: Audio pronunciation for every kana, row, column, and vocabulary word.

5. Home Screen Widget
• Review kana and vocabulary right from your Home Screen — no need to open the app!
