**[Meta to Launch "Stealth Chat" Feature on WhatsApp]** Meta Platforms (META.O) announced on Wednesday that the company is introducing a new "Stealth Chat" feature within the AI assistant of its WhatsApp instant messaging service, aimed at addressing user concerns over data privacy. Meta stated that Stealth Chat will rely on private processing technology to ensure conversations are invisible to anyone (including the company itself). In a blog post, Meta noted, "Your conversations will not be saved, and by default, messages will automatically disappear—this provides you with a space to think and explore ideas without being monitored by anyone." In the coming months, WhatsApp will also roll out "Sidechat," a contextual private AI assistant based on Private Processing, offering users confidential AI assistance within existing conversations.
