In this project-based tutorial, Brian tackles a common challenge for prolific builders: quickly spinning up professional one-page marketing sites for new tools and products. Rather than starting from scratch each time, he creates a reusable static HTML template that includes all the structural elements he typically needs—hero sections, navigation with smooth-scrolling anchor links, video modals, founder letters, and feature lists. Using Claude Code with the frontend design skill, he builds out a clean, responsive template with dark mode support.
Once the template is locked in as a GitHub template repository, Brian puts it to work immediately by creating a real marketing site for Inbox Summaries, a new AI-powered tool he recently built. He demonstrates his full workflow for writing marketing copy—pulling context from previous Claude conversations about the product, iterating on headlines and sub-headlines, and refining the founder letter. The video shows how to efficiently collaborate with AI on creative decisions while maintaining your own voice and vision.
