A San Francisco shop is operated almost entirely by a central AI agent that manages checkout, inventory and security. The Times examines how the system handles everyday tasks, misidentifies items and prompts privacy concerns. It shows both the promise and real-world glitches of automating retail with AI.

• Shelf.AI's cashier-less store cut labor costs 60% by using an AI agent ("Mia") to handle pricing, inventory, and theft prevention across cameras, weight sensors, and LIDAR
• 7% of opening-day transactions undercharged customers due to glitches, fixed within 48 hours—showing the tech isn't yet flawless
• Privacy concerns persist over constant surveillance, despite Shelf.AI's claims of discarding raw footage after 24 hours and encrypting data
• Early financials look promising ($45,000 weekly sales, break-even projected in 8 months), prompting other grocers to test similar AI systems

The Brave Search API lets developers access real-time web search data for applications like chatbots and AI tools. It offers features like summarized answers, high query capacity, and a focus on privacy with zero data retention. Plans include a monthly credit allowance for usage.

• Independent index of 30B+ pages (not reliant on Google/Bing) with millions of daily updates, plus $5/month free credits
• Handles up to 50 queries/sec standard, 2 queries/sec for AI-summarized answers
• Zero data retention policy keeps user queries private
• Custom enterprise plans available for larger-scale needs

Moxie Marlinspike, creator of Signal Messenger, is launching Confer, an open-source AI assistant designed to ensure user data remains private and unreadable by anyone except the account holders. Utilizing strong encryption and trusted execution environments, Confer aims to set a new standard for AI chatbots while maintaining user confidentiality and security.

• Moxie Marlinspike is launching Confer, an open-source AI assistant built so that not even server operators can access user conversations, using trusted execution environments and strong encryption.
• It's designed to avoid the key-management complexity typical of encrypted tools while still shielding data from platform operators, hackers, and law enforcement/subpoenas.
• The push comes amid real precedent for exposure, like the court order forcing OpenAI to preserve all ChatGPT user logs.
• Marlinspike is aiming to replicate Signal's model of simple, verifiable, privacy-first design in the AI chatbot space.

Many users are unaware that conversations with consumer AI about health issues lack legal protections, unlike communications with licensed healthcare providers. This article highlights the risks of disclosing personal health information to AI, which can be subpoenaed in legal situations, exposing users to potential misuse of their private data. It emphasizes the importance of understanding what privileges are lost when opting for AI assistance over traditional healthcare communications.

• Conversations with AI like ChatGPT or Claude aren't protected by legal privilege, unlike those with doctors or therapists, meaning they can be subpoenaed and used in court
• A wrongful death lawsuit already involved private mental health conversations being submitted as evidence
• OpenAI admits it doesn't train on user chats but authorized staff can still access them, leaving data vulnerable to legal requests
• Surveys show many users mistakenly believe AI chats carry the same confidentiality as conversations with doctors or lawyers
