手寫筆記、PDF 註記與 AI 學習工具，都在同一塊畫布上
低延遲墨跡、防誤觸手掌辨識、劃掉即擦除以及手寫轉文字，讓書寫接近紙筆手感。
匯入合約、論文或教材，用手直接標註，註記可搜尋並可乾淨匯出。
同時檢索鍵入文字、手寫與速寫，並把筆記轉成摘要、心智圖或結構化計畫。
在共享筆記本、文件和白板上同時協作，不再有版本衝突或反覆傳檔案。
把零散資料變成可建構世界觀的視覺化知識庫
把 PDF、網頁、YouTube 影片、播客以及 Readwise、Zotero 條目拆成卡片，並順著每條引文深入閱讀。
把任意目標轉化為個人化課程，並借助 AI 處理閱讀材料，再在白板上組織想法。
用巢狀標籤與屬性為知識建立可隨學習演化而重構的結構，而不是扁平的資料夾。
透過外掛、MCP 伺服器與 CLI，從 Claude Code、ChatGPT、Codex 或 Grok Bot 查詢你的知識庫。
專項更強將課程教材轉化為互動式 AI 學習工具，但較少專注於手寫數位筆記本。
專項更強Stronger online PDF editing and AI chat capabilities, but lacks tablet-optimized handwritten note-taking workflows.
