自信書寫：在一個編輯器內完成校對與事實查核
Factful 會以即時網路來源驗證事實陳述，並依可信度篩選找到的資料，而不只是比對字句。
校對與事實查核同時進行，讓你在同一個流程中修正表面錯誤與實質不準確之處，不必切換工具。
監看修正內容、追蹤你的準確度隨時間的變化，並找出跨主題重複出現的錯誤。
產品稱之為「Everything Key」的指令系統，讓你無需離開正在編輯的那一行，就能觸發寫作與格式設定動作。

在 Microsoft Word 中自動獲取上下文相關的語言回饋，並可改寫、更改風格、解釋或總結文本。
在 Overleaf 中直接於 LaTeX 程式碼內獲得語言回饋，自動生成 LaTeX，並使用 TeXGPT 處理表格、公式與方程式。
投稿前上傳文件，查看整體語言品質，並用修訂痕跡套用修正。
