用對話生成圖表與示意圖,幾秒出圖
用自然語言描述想要的圖表即可取得渲染結果,以聊天式提示取代複雜的圖表設定面板。
不限於圖表,也能依文字描述產生結構化示意圖,用來表達流程與關聯。
不需安裝或本機設定,打開網站、輸入需求,直接使用生成的成果。
在很短時間內得到一版視覺化初稿,之後再精修或換風格,無需從空白畫布開始。

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。
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.
