「教科書を読んだのに、いざ問題を解くと答えが出てこない」——その原因は、読み返すだけの復習が「見れば分かる」という錯覚を生んでいるからです。 おもいだしトレーニングは、覚えたい範囲や単語・論点をテキスト入力(または写真撮影)するだけで、AIが穴埋め・一問一答形式の想起クイズを自動生成する暗記アプリです。1問ずつ集中して思い出すウィザード形式で出題し、解答後はAIが理解度を判定してフィードバックします。 ■ こんな人におすすめ ・資格試験や定期テストの範囲を、読み返すだけで済ませてしまいがち ・単語や年号など、覚えたのに本番で思い出せないことが多い ・何を復習すればいいタイミングか分からず、計画倒れになりがち ・テスト形式で自分の理解度を客観的に確認したい ■ 主な機能 ・AI想起クイズ自動生成:覚えたい範囲をテキストまたは写真で入力するだけで、穴埋め・一問一答クイズをAIが作成 ・1問ずつのウィザード出題:全問一覧にせず、1問ずつ答えを考えさせてから正解を表示 ・難易度選択:易しめ・標準・踏み込んだ問いの3段階からAIへの出題傾向を指定可能 ・間隔反復による復習管理:自己評価をもとに次の復習タイミングを自動計算し、忘れる直前に再出題 ・AI理解度フィードバック:解答内容をAIが判定し、惜しい点・改善点を一言で返す ・弱点復習モード・タグ管理:正答率の低い論点だけを抽出して再テスト、タグで科目ごとに管理 ・連続記録(ストリーク)表示で継続を後押し 読むだけの勉強から、思い出す練習へ。おもいだしトレーニングは、「テストなしでもスラスラ言える自分」になるための最短ルートを提供します。 1日の利用回数には上限があります(アプリ内でご確認いただけます)。広告は一切表示しません。
