WhatsApp Scam Alert
WhatsApp started a limited beta for Scam Alert, a feature that runs a small machine-learning model directly on the user's phone. The system flags messages from unknown senders when their conversational structure matches known scam patterns, without sending the content to a server. Devices aggregate warning counts locally and transmit them through Oblivious HTTP relays to maintain differential privacy before Meta sees the population-level figures.[1]
Meta AI on Mac
Meta released a Mac application for its AI assistant, joining existing desktop clients from Gemini, ChatGPT and Claude. The software can read a shared window to answer questions, generate content based on what is on screen, and provide dictation services across other applications. The assistant also connects directly to Meta advertising campaigns, Google Workspace and Instagram accounts to run recurring tasks such as weekly performance updates.[2]
Amazon Alexa+
Amazon made its Alexa assistant free on compatible Fire TV devices in the United States, removing the previous monthly cost for non-Prime members. The upgrade delivers conversational search and smart-home control to televisions without requiring a download or sign-up. The move accelerates the integration of generative features into living rooms, as customers reportedly hold nearly twice as many conversations on the upgraded interface.[3]
