For personal automation: Using Codex to control a logged-in browser via Chrome extension.

For work automation: Installed "Playwright Chrome Extension" on work browser + GitHub Copilot CLI to automate expense reports and internal site operations.

Why this approach? Need to interact with authenticated internal company sites. Could use Persistent Profile mode, but the extension method is simpler and behaves nearly identical to Codex.

Tech stack:

- Codex (personal)

- Playwright Chrome Extension + GitHub Copilot CLI (work)

- Both leverage existing browser sessions for authenticated automation

Key advantage: No need to handle login credentials or session management - just piggyback on already-authenticated browser instances.
