Claude gets a 'Reflect' dashboard: Spotify Wrapped for your AI habit - and a masterclass in retention design

Anthropic launched Reflect, a beta dashboard (Free, Pro, and Max users with Memory on) that visualises Claude usage over 1-12 months - top topics, task types, peak hours - and coaches you via its 4D AI Fluency Framework (delegation, description, discernment, diligence), suggesting features like Projects or custom skills based on your patterns. It ships wellbeing controls (quiet hours, break nudges, reflection prompts) built with MIT Media Lab and Boston Children's Hospital experts, and excludes health-linked conversations entirely. TechCrunch's sharp read: beneath the mindfulness framing, Reflect showcases how much of your work runs through Claude - a retention play as much as a wellness one.

Gemini Spark lands on the Mac: Google's 24/7 agent starts working your local files

Gemini Spark, Google's 24/7 agentic assistant, is now available on Mac (beta, US-only, Google AI Ultra subscribers), where it can work directly with files on the computer - sorting and organising them, or turning a folder of invoices into a budgeting worksheet in Google Workspace. The update adds long-requested Google Tasks and Keep integrations plus third-party hooks into Canva, Dropbox, Instacart, OpenTable, and Zillow Rentals, real-time tracking of topics like stocks and breaking news, and - notably for builders - custom MCP support for wiring in your own apps. It puts Spark in direct competition with Claude Desktop, Microsoft Copilot, and OpenClaw for the desktop, where the real productivity (and governance) questions live.

L'Oreal has announced a wide-ranging collaboration with OpenAI, unveiled at VivaTech 2026, that brings Maybelline's virtual makeup try-on directly into ChatGPT via L'Oreal's ModiFace AR technology.
