Meta在WhatsApp推出“隐身对话”功能，用户可与Meta AI进行完全私密的聊天，内容在隔离的安全环境中运行，无人可查看。操作简单：在对话界面点击隐身图标即可开启，独立版Meta AI应用也将同步支持。
Meta公司于2026年5月13日在WhatsApp及独立Meta AI应用中推出“隐身模式”，允许用户在隔离环境下与AI对话，解决隐私数据留存问题。开启后，对话记录不存储，关闭窗口或应用时自动终止会话并清除上下文信息。
AI搜索引擎Perplexity因隐私问题被起诉，指控其“隐身模式”无效，用户聊天记录被共享给谷歌和Meta用于广告投放。诉讼称无论用户是否登录或开启隐私保护，对话内容均被自动共享，涉嫌严重侵犯隐私。
Perplexity AI因涉嫌未经用户同意向Meta和Google等第三方共享敏感对话数据，在美面临集体诉讼。诉状称即使用户开启隐身模式，其财务、税务等隐私信息仍可能被追踪工具泄露。公司回应尚未收到正式诉讼文件。
