South Korea's LetinAR Is Building the Optics Behind AI Glasses

TechCrunch reports on LetinAR, a South Korean startup developing miniaturized optical components aimed at powering the next generation of AI-enabled smart glasses. According to the report, the company produces a lens roughly the size of a thumbnail that could serve as a foundational optical component for AI glasses hardware.

LetinAR's technology is positioned to address one of the core engineering challenges in wearable AI devices: delivering high-quality optics in an extremely compact form factor. TechCrunch describes the startup as a potential "optical backbone" of the emerging AI glasses ecosystem, suggesting its components could find their way into products from multiple hardware manufacturers as the category matures.

The report highlights the growing investment and development activity around AI-integrated wearables, with specialized component suppliers like LetinAR playing an increasingly important role in the broader hardware stack.

Apple's Revamped Siri Reportedly Set to Feature Auto-Deleting Chat Histories

Both TechCrunch and The Verge are reporting on details surrounding Apple's upcoming overhaul of its Siri assistant, with privacy shaping up as a central design consideration.

According to Bloomberg's Mark Gurman, as cited by The Verge, the more conversational, chatbot-style version of Siri expected to debut in iOS 27 will include an option for users to automatically delete their chat histories. TechCrunch similarly notes that privacy is expected to be a major theme when Apple formally unveils the new Siri.

The Verge notes that Apple is positioning its established privacy track record as a potential differentiator in the increasingly competitive AI assistant market. The auto-delete feature would give users direct control over their conversation data, aligning with Apple's broader platform-level privacy messaging.

The revamped Siri has been anticipated as a significant step forward for Apple Intelligence, as the company works to close the gap with other large language model-powered assistants currently available on competing platforms.
