面向云规模工程团队的统一可观测性、安全与事件响应平台
agent、云集成与 OpenTelemetry 采集器把指标、分布式追踪、性能剖析与日志汇入同一平台,可在不同信号之间直接跳转,无需切换上下文。
Bits AI、Agent Builder 与 LLM/AI Agent 可观测性能力,帮助团队快速研判告警、解释异常,并监控模型延迟、token 花费与 agent 调用链。
Cloud SIEM、云安全态势管理、漏洞管理、工作负载防护与代码扫描,把威胁信号与已有的遥测数据关联起来。
真实用户监控、会话回放、产品分析、合成与移动端测试,与 CI 可见性、测试优化、功能开关和 DORA 指标并列提供。

手写笔记、PDF 批注与 AI 学习工具,都在同一块画布上
低延迟墨迹、防误触手掌识别、划掉即擦除以及手写转文字,让书写接近纸笔手感。
导入合同、论文或教材,用手直接标注,批注可搜索并可干净导出。
同时检索键入文本、手写与速写,并把笔记转成摘要、思维导图或结构化计划。
在共享笔记本、文档和白板上同时协作,不再有版本冲突或反复传文件。
