## Resource

Learn how to leverage Codex's browser and computer use capabilities to automate complex digital workflows. This episode demonstrates practical applications ranging from automated QA testing to hands-free personal shopping.

## Highlights
- Main idea: Browser and computer use allow LLMs to act as virtual coworkers by controlling your mouse and keyboard
- Practical takeaway: Use 'under-prompting'—providing minimal instructions—to allow frontier models to navigate complex UI more effectively
- Failure mode: Browser use can be slow, so it is best used for background tasks while you focus on other work
- Practical takeaway: Combine browser use with iPhone mirroring to allow your Mac to perform remote hardware configurations via your phone
- Main idea: AI agents can serve as synthetic users by impersonating specific personas to identify friction points in software products
