Have you considered making the model leverage computer use via Work/Codex?

I'd imagine making the agents use the same tools that people utilize would greatly dial back how AI-generated these things look, and it would provide much better control too.

With Astra being genuinely much better at this, it should be more viable than ever.

If you break out more sophisticated tools - give Claude Code some skills, let it work in SVG or PDF, create bitmap assets and composite them with real fonts and vector assets, I'm sure you can achieve a lot.

But the point of this blog post was to demonstrate what a PTA mum can achieve even with just ChatGPT, if they just prompt a little more creatively.

The proviso though is that you don't get many tries on free tier. Or if you pay for more tokens, you can fall into a rabbit hole of iterating where it's no longer a quick task.
