把筆記變成記得住的閃卡
上傳 PDF、PowerPoint 或 Keynote 投影片、Word 與 Pages 文件、圖片或講座音訊，生成的閃卡完全來自你的原始內容。
記得住的卡片間隔就拉長，忘記的則縮短；反覆記不住的卡片會標記為關鍵卡片，方便你改寫。
從你的材料產生完整測驗與限時模擬考，並可練習口試，系統會評估你實際說出的內容。
卡住時可隨時提問，也能請 Ka 把材料重做成新卡片、測驗或筆記。
把課堂、會議、PDF 與影片變成結構化筆記、單字卡與測驗
手動輸入、錄音、上傳音訊（支援 MP3、WAV、M4A、AAC、OGG）、匯入 PDF 與 Word 檔、加入網頁或影片連結，或以多語言 OCR 掃描圖片與截圖。
每份筆記都能產生摘要、單字卡、測驗、心智圖、資訊圖、Podcast，以及可追問的 AI 對話，全部對應同一份來源素材。
錄音會變成完整逐字稿加摘要，並可在編輯器中把下一步轉為待辦清單，紀錄透過一個連結即可分享。
提問得到的回答來自你自己的文件而非通用模型知識，讓複習與查核事實更可靠。
