提供即時文法糾錯、語氣校準、寫作來源追蹤與團隊風格指南的跨平台 AI 寫作助理。
在 Chrome、Safari、Firefox、Edge、Windows、Mac、Google Docs、MS Office 與行動鍵盤中原生運行,標出文法錯誤、重寫繞口句子,並將語氣轉向自信、共情或高階主管口吻。
部署具上下文感知的 AI 代理,預測目標受眾會如何反應草稿、定位可信的支撐引文、依評分規準批改文章,並在 Pro 方案下每月使用最多 2,000 次提示生成草稿。
對照數十億網頁與學術資料庫掃描文字以找出無意抄襲,識別 AI 生成的段落,並透過 Google Docs 與 Word 中的 Authorship 報告透明記錄文件來源。
讓 Pro 與 Enterprise 方案的團隊能夠固化公司術語、禁用過時行話、強制使用包容性語言、插入共享片段,並在行內顯示公司內部定義。

偵測 AI 寫作、改寫被標記的句子,並在同一頁重新檢測
文中每個句子都會取得獨立的 AI 信心分數與顏色標註,直接指出該改哪幾行,而不是只給一個籠統的總體結論。句子級細節自 Starter 方案起提供。
0–100 的分數,寫作越自然分數越高;每次掃描都會重新計算,讓你在編輯過程中直觀看到數字變化。
改寫引擎只處理讀起來像 AI 所寫的段落,保留原意與語氣。免費帳戶每次約 260 字,付費方案每月增加數千至上萬字,並解鎖 Advanced、Business、Casual 等改寫模式。
偵測、改寫與重新評分都在同一個視窗完成。人性化改寫後可直接對同一段文字複檢,並排比較改寫前後的 AI 比例。
