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。

長時程 AI 代理人,端到端完成保險與金融服務工作
持續數小時甚至數天不間斷工作的長時程代理人,會針對證據與風險進行推理,而不只是給出建議。
面向承保公司、金融機構、TPA 與貸款機構,覆蓋 16 條業務線,包括車險、財產險、旅平險、壽險、健康險、商業險、職災補償、資安險與房貸。
Strata 讓使用者用自然語言拉取報表、查詢代理人機隊、調整代理人行為,甚至為某個流程打造並上線全新代理人。
代理人跨團隊已經在用的工具運作,無需推倒重建,也無需強制遷移到新的記錄系統。
