Today I’m walking you through one of my absolute favorite AI features right now: browser and computer use via Codex (the ChatGPT desktop app). I use this every single day, personally and professionally, and I wanted to share the specific workflows I’ve built, the moments that surprised me, and the mental model that makes it actually click. What you’ll learn: 1. How browser use and computer use work, and why the Codex desktop app plus Chrome extension is the combo I rely on 2. How I use Codex to QA my onboarding flow, including exhaustive mobile testing I would never do manually 3. Why under-prompting frontier models gets better results than detailed step-by-step instructions 4. How my husband EJ Lawless’s persona-impersonation trick surfaces friction points I can’t see as the builder 5. How I use browser use to get through my LinkedIn inbox without touching it myself 6. How I had Codex shop Free People’s sale and add 10 medium items to my cart (breastfeeding-friendly and Hawaii-ready) 7. How computer use can control iPhone mirroring so your Mac can technically operate your phone 8.
