Description: John Bai and Peng Zheng are designers on the Grok Bot team at SpaceXAI, where they’re building one of the most talked-about AI products right now. John writes publicly about his design process (his piece “Designing Grok Bot with Grok Bot” has already made the rounds) and shares bot templates with the design community. Peng brings a product-design sensibility to personal tools, and his website doubles as a live demo of what he builds.What you’ll learn:How Peng built a self-updating personal website using Grok Bot as the entire backend pipeline, with no CMS and no Figma fileThe exact check-in bot setup that lets Peng send a photo or a place name and have his portfolio update itself automaticallyHow John’s Figma Bro bot handles production design tasks while he’s at the gymHow John uses voice memos to direct Figma work through an MCP connection without opening his laptopThe “shower thought to prototype” workflow John uses with DevBot to test interaction ideas without first going through a product manager or engineerThe “trash can method” of software developmentHow both designers organize their personal bot ecosystemsWhat John and Peng actually think AI means for the future of design as a craft—Brought to you by:WorkOS—Make your app enterprise-ready, with SSO, SCIM, RBAC, and moreVanta—Automate compliance and simplify security—In this episode, we cover:(00:00) Introducing John and Peng(02:53) The Grok Bot hype train(04:35) Peng’s self-updating personal website built with Grok Bot(15:12) How AI makes design more accessible(19:35) Website update result(20:13) John’s Figma Bro bot(23:35) Creating marketing materials for the bot marketplace(26:00) DevBot: from shower thoughts to working prototypes(28:48) The trash can method of software development(31:19) Other bots John and Peng are using(39:05) Practical tips for when bots don’t do what you want—Tools referenced:• Grok Bot (xAI): https://x.ai/bot• Figma: https://www.figma.com• Figma MCP server: https://www.figma.com/mcp-catalog/• Google Places API: https://developers.google.com/maps/documentation/places/web-service• Notion: https://www.notion.so• Swarm (Foursquare): https://www.swarmapp.com—Other references:• Designing Grok Bot with Grok Bot: https://x.ai/bot/guides/designing-grok-bot-with-grok-bot• Figma Bro bot template (shared by John Bai): https://x.ai/bot/marketplace/bots/figma-bro• From zero coding background to hardware hacker: How Cursor + a Raspberry Pi makes AI fun: https://www.lennysnewsletter.com/p/from-zero-coding-background-to-hardware?utm_source=publication-search—Where to find John and Peng:John Bai on X: https://x.com/johnbaiPeng Zheng on X: https://x.com/pengzheng_—Where to find Claire Vo:ChatPRD: https://www.chatprd.ai/Website: https://clairevo.com/LinkedIn: https://www.linkedin.com/in/clairevo/X: https://x.com/clairevo—Production and marketing by https://penname.co/.
