Tell AI What NOT to Do: Negative Prompting
Sometimes telling AI what NOT to do is just as important as telling it what to do.

The big idea
AI is a people-pleaser. If you do not say what you don't want, you might get exactly that thing. Speak up about what to skip.
Some examples
- 'Make me a snack idea — but no peanut butter, I am allergic.'
- 'Tell me a story — but do not make it scary.'
- 'Help with my essay — but do not write the actual sentences. Just give me ideas.'
- 'Give me jokes — but keep them clean and school-appropriate.'
Try it!
Ask AI for a story. Then ask again, adding 'but no animals can talk in this one.' Notice how it adjusts.
Practice this safely
Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about negative prompts, not to let it make the decision for you.
- 1Ask AI to explain negative prompts in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "Tell AI What NOT to Do: Negative Prompting" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check negative prompt against a trusted source, teacher, adult, expert, or original document before you use it.
