保育園・幼稚園・学校のおたよりを撮るだけ。日付・時間・持ち物をAIが読み取って、家族の手帳に自動で追加します。手入力も、冷蔵庫の貼り紙とのにらめっこも、もういりません。 ◆ こんな経験はありませんか ・冷蔵庫がおたよりで埋まっている ・行事の日付を手帳に写すのを忘れていた ・「あした体操服の日だった」と前の日の夜に気づく きょうだいで園や学校が別々なら、おたよりは月に10枚以上。整理しきれないのは、あなたのせいではありません。 ◆ きづきができること 【撮るだけで、予定になる】 おたよりをカメラで撮ると、AIが日付・時間・持ち物を読み取って予定に。だいじなところにはマーカーを引いてお見せします。 【今やることは、ひとつだけ】 ホームを開くと、「今夜は、ひとつだけ。」と、いま いちばん大事なことだけお知らせ。済んだら「済」のハンコを押すだけです。先の持ち物は きづきの預かり帳がおぼえていて、その日のよるに、また言います。 【家族の手帳になる】 予定は子どもごとに色分けされて、手帳のページに並びます。月・週・リスト表示にも切り替えられます。Googleカレンダーとの同期にも対応。 【前の日の夜に、そっとリマインド】 持ち物は前夜のうちにお知らせ。当日の朝にあわてません。 【家族で、おなじ手帳を】 招待コードでパートナーを招待すると、同じ予定と持ち物をいっしょに見られます。どちらかが済ませたら、もう片方に「済」が届きます。 【わからないことは、正直に】 AIのよみとりに自信がないときは「自信がありません」とお伝えします。なぜこの予定を選んだのか、理由もいつでも確認できます。 ◆ AIチャット「きづき」(プレミアム) 「遠足の持ち物は?」と聞くと、スキャンしたおたよりの内容から答えます(月30回)。 ◆ 料金 ・無料: スキャン月10回 / 家族メンバー2人まで / 子どもの登録は無制限 ・プレミアム: 月額480円、または年額3,800円(月あたり400円) スキャン無制限 / AIチャット / 家族メンバー無制限 / 3ヶ月より前のおたよりもさかのぼって閲覧 ◆ こんな方に ・共働きで、おたよりを見る時間が夜しかない ・きょうだいで園や学校が別々 ・夫婦で予定と持ち物を分担したい カメラで撮れれば、それでじゅうぶん。 まずは1枚、おたよりを撮ってみませんか。

Verdict
The clearest difference is update cadence: きづき at every 3 days against Creta Class's fortnightly. Creta Class's advantage is iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
