TL;DR
What did u/cimocw use ChatGPT for?
Thinking the dark part of the moon was Earth's shadow, a ChatGPT user asked it for a small visual model of the lunar phases and kept refining it until it explained them simply. They say they used to think ads showing kids studying with interactive animations and infographics were gimmicky, until they did it themselves and it worked.
What they did
Out on a walk, they realized they didn't really understand how lunar phases work. They had assumed the dark part of the moon was Earth's shadow, which didn't quite make sense. So they asked ChatGPT and spent some time refining a small interactive model with it until it showed how the phases work in a simple, visual way.
How it went
They say they used to think ads showing kids studying with interactive animations and infographics were gimmicky, until they did it themselves and it worked.
Worth knowing
- A model is only as right as the explanation behind it, so check the main idea against a trusted science source. Expect a few rounds of asking for changes before it is clear.
- Price check: ChatGPT: free plan; Go: US$8/month (checked Nov 8, 2026).

Try it yourself
Paste this into a chatbot, then add your own details underneath.
I want to understand [topic, like why the moon has phases]. Right now I think [your current idea], but I'm not sure. Build me a simple interactive visual I can play with here that shows how it really works, with short labels in plain language. Then tell me what was wrong with my original idea.
