「書けない」を、「話す」だけで。 sonata は、AIがインタビュアーになってあなたに質問するアプリです。 自分で一から文章を書くのは大変だから、誰かに質問してもらえたらいいのに... そんなあたなに、答えを声で話すだけで、長文の記事ができあがります。 ■ こんな方へ ・発信したいことはあるのに、文章にする時間がない ・自分の専門や仕事を言葉にして届けたい ・ChatGPTで書こうとしても、自分の言葉にならない ・継続して発信したいけれど、書くこと自体が続かない 書くのが得意でなくても、話すことならできる。 sonata は、その「話せる」を記事に変えます。 ■ できること 1. 記事のテーマを決める 書きたいことを一言入れると、AIがあなたに合わせた質問を用意します。 2. AIの質問に、声で答える AIがインタビュアーとして質問を読み上げます。あなたは話すだけ。 答えが浅いところは、AIがもう少し詳しく聞き返してくれます。 3. 記事ができあがる 話した内容を文字起こしし、見出し・本文・まとめのある記事に整えます。 4. どこへでも発信する 完成した記事はMarkdownでコピーできます。 Substack、Medium、note、X Article など、発信先は自由です。 ■ あなたの文脈を覚えます プロフィール(肩書き・発信したいテーマ・あなたらしさ)を登録しておくと、 記事の語り口や切り口にそれが反映されます。 回を重ねるほど、あなたの言葉に近づきます。 作った記事は一覧で見返せます。書いた分だけ、発信が積み上がります。 ■ なぜ「話す」なのか 文章を書く作業には、構成を考え、言葉を選び、推敲するという負荷があります。 その負荷が、発信を諦めさせてきました。 sonata が置き換えたいのは、ChatGPTで自分でプロンプトを設計して書く体験ではありません。 「話すだけで、発信を続けられる」体験です。 いちばんの競合は、発信を諦めてしまうこと。 その壁を、いちばん低くしたいと考えています。 sonata は、音声からWeb調査・企画・文字起こし・記事生成までの一連のワークフローで特許出願中の技術を、個人の発信のために再設計したアプリです。 ※特許出願中(特願2025-146411号) 開発・運営: opus合同会社 プライバシーポリシー: https://sonata-ai.app/privacy 利用規約: https://sonata-ai.app/terms
