Japanese keyboard input (romaji → kanji conversion) is slow. Speak your study notes instead and generate flashcards, quizzes, and summaries instantly.
Japanese typing is uniquely slow. Unlike English where you press a key and get a letter, Japanese input requires typing romaji, waiting for conversion candidates to appear, and selecting the correct kanji from a list. This romaji → kanji conversion process interrupts your study flow constantly — every few characters, you're scanning a dropdown menu instead of focusing on the material you're trying to learn.
Speaking your notes directly is 3-5x faster than typing in Japanese. Most people speak at 150 words per minute but type Japanese at roughly 30-40 characters per minute after accounting for conversion time. Voice input removes the keyboard bottleneck entirely — just speak naturally and your notes appear as text.
This makes voice input perfect for reviewing textbook content, summarizing lectures, or recording study thoughts on the go. The voice recognition handles Japanese naturally — speak in Japanese and your speech is transcribed accurately, including kanji, without any manual conversion. You can then review the text, make any edits, and generate flashcards, quizzes, or summaries from your spoken notes.
