為內容完整性打造的企業級 AI 與抄襲偵測
辨識超過 30 種語言與主流 LLM 的 AI 生成文字，內部英文測試集準確率宣稱超過 99%。
搜尋 60 兆個網站、16,000 多種開放取用期刊與內部資料庫，揪出改寫與隱藏複製。
將偵測延伸至 AI 生成的影片、音訊與圖像，讓團隊能驗證文字以外的內容。
可擴充的 API 與工作流程整合，自動化 LMS、出版工具與企業系統中的內容分析。
在交出鑰匙前驗證收入、身分與文件
申請人透過 Plaid 連結銀行與薪資帳戶，收入直接從帳戶讀取，最可靠的路徑上沒有可偽造的文件。上傳文件的情況也會分析入帳頻率與實際收入。
身分證件正反面拍照，搭配即時自拍並以人臉辨識確認一致，在交鑰匙前攔下借用身分的情況。
上傳的 PDF 以位元層級解析，檢查隱藏文字層、中繼資料不一致、產生器指紋與事後編輯，找出肉眼看不到的證據。
每份申請給出五種判定之一（通過、附註意事項通過、非經常性、需人工複核、未通過），並附風險等級與觸發訊號。
