在 Gmail 與 Outlook 中依你本人語氣撰寫郵件的 AI 助手
ForthWrite 讀取你已寄出的郵件建立語氣檔案，約每 50 封擷取郵件更新一次，讓草稿持續跟上你寫作風格的變化。
Pro 使用者開啟 Gmail 時回覆已備妥，並可平行處理數十個討論串，無須逐封手寫。
草稿會依收件人調整語氣，並把跟進、引薦、進度回報視為各自不同的任務，而非套用同一模板。
對提示詞做版本管理與 A/B 測試，並透過可量化的改善曲線追蹤採納率、語氣貼合度與意圖分布。
直接嵌入 Word、Excel、Outlook、PowerPoint 的隱私優先 AI 增益集。
透過 Microsoft Office 增益集商店，在 Windows、Mac、網頁與 iPad 的 Word、Excel、Outlook、PowerPoint 中運作。
用自己的 API 金鑰啟用 OpenAI、Google Gemini 或 xAI Grok 模型，自行掌握供應商與花費。
各版本附有快速操作提示、角色人設、寫作風格與語氣，以及創意程度與回覆長度控制。
