Have Codex operate a product demo while you narrate
Codex + Chrome + Computer use
Once the fashion-design prototype worked, I wanted to record a tour. I had Codex put Chrome back on the starting screen and wait for my cue. Then it drove the demo slowly enough for me to talk over it.
It changed the outfit, showed the customization controls, saved a look, and took the character onto the runway and rooftop, with pauses along the way. That let me concentrate on explaining what we had built instead of remembering the clicks while narrating. This was the on-screen demo pass; the workflow didn’t include editing or exporting the recording.
# Run a product tour while I narrate
Adapted from this workflow; not the original transcript.
Use the open browser to demonstrate [product]. First inspect the working app and propose a short sequence showing [features]. Use sample data suitable for a public recording.
Reset the app to a clean starting screen and wait for me to say go. Do not begin before my cue.
When I say go, operate the demo slowly. Pause after each meaningful change so I can explain it. Keep the cursor clear of the result where possible. If something fails, stop and tell me rather than clicking through it.
End on [desired closing state]. Leave the app there.
