How Two XAI Designers Use Grok Bot for Their Jobs

Executive Signal Summary

In this episode of the 'How I AI' podcast, host Claire Vo interviews John Bai and Peng Zheng, designers on the Grok Bot team at SpaceX AI (xAI), about their use of AI agents in daily workflows. Peng demonstrates a check-in pipeline where he sends photos or location names to a custom Grok Bot, which uses Google Places API and image generation to create 3D miniature visuals for his personal website, automating publishing. John shows how he uses Grok Bot with Figma MCP to edit designs, create marketing materials from templates, and generate interactive prototypes from voice commands. They discuss how AI reduces tedious work, enables creative exploration, and shifts designers toward higher-level decisions, emphasizing configuring bots with clear, narrow responsibilities for tasks like email triage and calendar management. The episode is sponsored by WorkOS and Vanta.

macOS 27: New Siri takes on AI productivity apps

Apple's macOS 27 'Golden Gate' update introduces a major Siri AI overhaul, making it a system-wide AI interface and direct competitor to AI productivity apps. The new Siri can be invoked anywhere on screen to analyze visible content, incorporate context from files, emails, and messages, and assist with actions across applications. Enhanced Spotlight serves as a universal command center with expanded search for actions, clipboard contents, and previous queries. Generative writing features are built into the OS, while Safari gains AI-powered website monitoring and tab grouping, and Finder gets filename suggestions. Notably, in the EU, the new Siri AI is available on Mac and Vision Pro first, strategically positioning the Mac as a testing ground before broader rollout. The update is available now for compatible Macs.
