FlowNoteは、テキスト入力を起点として、日々のタスクとスケジュールをシームレスに統合管理できる、インテリジェントな生産性向上アプリケーションです。 ユーザーが「14-15時に会議」といった自然な言葉でメモを入力すると、アプリがその内容を解析し、自動でタスクや予定を生成します。 生成されたタスクは、視覚的に把握しやすい付箋(スティッキーノート)としてキャンバス上に表示され、カテゴリごとに分類したり、自由に整理したりすることが可能です。さらに、これらの付箋をタイムライン形式のカレンダーに直接ドラッグ&ドロップすることで、簡単に時間と紐づけ、具体的なスケジュールに落とし込めます。 思考の断片を素早く捉え、それを具体的な行動計画へとシームレスに繋げることで、ユーザーのタスク管理と時間管理を円滑にサポートすることを目的とします。
