Summary

The creator uses Codex for small non-coding chores, such as reducing a photo's file size for his YouTube channel. He finds this easier than doing it in Canva.

Key points

• Coding agents can do small file-manipulation jobs like resizing or compressing images.
• Asking the agent can be faster than opening a design tool such as Canva.
• The agent can write and run the script for you, so you don't have to.
