為雲端規模工程團隊打造的统一可觀測性、安全與事件應變平台
agent、雲端整合與 OpenTelemetry 收集器把指標、分散式追蹤、效能剖析與日誌集中到同一平台,可在各種訊號之間直接跳轉。
Bits AI、Agent Builder 與 LLM/AI Agent 可觀測性能力,協助團隊快速研判告警、說明異常,並監控模型延遲、token 花費與 agent 呼叫鏈。
Cloud SIEM、雲端安全態勢管理、漏洞管理、工作負載防護與程式碼掃描,將威脅訊號與既有遙測資料相互關聯。
真實使用者監控、工作階段重播、產品分析、合成與行動測試,與 CI 可視性、測試最佳化、功能旗標及 DORA 指標並列提供。

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。
