リマインダーをセットするだけ。時間になったら、AIが動き出しやすい「ひと押し」を用意します。 AIリマインダーくんは、予定管理アプリではなく、初動の心理的ハードルを下げることに特化したリマインダーアプリです。何を思い出したいかと、いつ知らせてほしいかを短く入力するだけ。あとは、通知のタイミングで「まずはこれだけ」という小さな一歩と、必要に応じてAIが用意した下書きや確認リストを受け取れます。 主な機能 ・シンプルな3ステップでリマインダーを作成 ・通知時刻に合わせたローカル通知 ・「ひと押し」画面で最初の一歩を提示(メールを開く、電話アプリを開くなど) ・AI準備(任意):返信下書き、確認事項、関連メモなど(Gemini APIキーを設定した場合) ・「もう少しあとで」で負担の少ない再通知 ・完了したリマインダーの振り返り こんな方におすすめ ・タスク管理は重く感じるが、リマインダーだけは使いたい ・通知は来るのに、最初の一歩で止まってしまう ・連絡や事務作業の「着手」を小さくしたい ・責めない言葉で、そっと背中を押してほしい APIキーは端末のKeychainに保存されます。キーを設定しない場合も、通常のリマインダーと通知として利用できます。
