## Whisper Notes Description
Whisper Notes — おそらく最高のオフライン文字起こしアプリ

一度の購入で、ずっとあなたのもの。
録音、インポート、文字起こし——すべて100%デバイス上で完結。データがクラウドに送られることは一切ありません。

60,000人以上のジャーナリスト、研究者、プロフェッショナルに信頼されています。

■ 主な機能
- 会議、講義、アイデアを録音——100%オフラインで文字起こし、データはデバイスの外に出ません
- アイデアを瞬時にキャプチャ——ロック画面、コントロールセンター、アクションボタン、または「Hey Siri」と言うだけ
- あらゆるアプリから音声・動画をインポート（LINE、WhatsApp、写真、ボイスメモなど）——字幕の抽出も可能
- 時間制限なしで録音——飛行機の中、トンネルの中、インターネットのない場所でも動作
- 100以上の言語に対応、自動検出（日本語に最適化）——文の途中で言語を切り替えても対応
- 複数の文字起こしモデル（Parakeet、Whisperなど）——用途に合わせて自由に切り替え
- SRT、VTT、TXTで書き出し——字幕用のタイムスタンプ付き、またはメモ・文書用のプレーンテキスト
- 一度の支払いですべてアンロック——継続的なアップデートと新機能

■ プライバシーとスピード
あなたの録音は常にデバイス上に残ります。インターネット不要、クラウドへのアップロードは一切なし。

iPhone 15での5分間の音声文字起こし：Parakeetで約18秒、Whisperで約1分。それぞれのモデルに強みがあり、言語や用途に合わせて自由に選べます。古い機種はやや遅くなりますが、問題なく動作します。

■ 正直な価格設定
一度の購入で、ずっとあなたのもの。
同様のアプリの多くは年間¥15,000以上——私たちは一回だけ。
サブスクリプションなし、アプリ内課金なし、広告なし。
ご満足いただけない場合は、設定 → 返金リクエストをタップしてください。

■ よくある質問

完全にオフラインで動作しますか？
はい。音声データはデバイスから一切外に出ません。飛行機の中、僻地、どこでも動作します。

LINEやWhatsAppの音声メッセージや動画を文字起こしできますか？
はい。LINEやWhatsAppから音声・動画を共有または保存して、Whisper Notesでオフライン文字起こし。クラウドにアップロードせず字幕を抽出できます。

録音時間に制限はありますか？
制限はありません。何時間でも録音できます。長い録音は文字起こしに時間がかかるだけです。

録音中のリアルタイム文字起こしに対応していますか？
録音中は非対応ですが、文字起こし中はリアルタイム表示されます。録音終了後、テキストが順次生成されていく様子を確認できます。

データはどこに保存されますか？
デバイス上のみです。私たちはアクセスできません。ご注意：アプリを削除すると録音も削除されます（秘密のバックアップは行っていません）。重要なファイルは定期的にエクスポートしてください。

AI要約がないのはなぜですか？
プライバシーのためです。録音をAIサービスにアップロードすることは一切ありません。要約が必要な場合は、テキストをコピーしてお好みのAIツールをご利用ください。データを閉じたシステムに閉じ込めることはしません。

アプリを切り替えると文字起こしが止まるのはなぜですか？
iOSがサードパーティアプリのバックグラウンドGPU使用を制限しているためです。アプリに戻って「再文字起こし」をタップすれば再開します。

推奨デバイスは？
iPhone 12以降。古い機種（iPhone 11、iPhone SE 第2世代）は非推奨です。アプリが正常に動作しない場合があります。

対応言語は？
日本語、English、한국어、简体中文、繁體中文、Español、Français、Deutsch、Português、Hindi、Arabic、Русский、Italiano、Nederlands、Polski、Svenska、Norsk、Dansk、Suomi、Türkçe、Tiếng Việt、Thai、Bahasa Indonesia、Bahasa Melayu、Čeština、Română、Magyar、Українська、Greek、Hebrew、Bengali、Tamil、Telugu、Urdu、Persian、Mongolian、Tibetan、Myanmar、Khmer、Lao、Nepali、Tagalog、Català、Hrvatski、Bulgarian、Kiswahili、Afrikaans、Српски、Slovenčina、Bosanski、その他50以上の言語に対応。
