How to Use AI to Write Quick Sub Plans (Even in an Emergency)

If you’ve ever stayed up late writing a last-minute sub plan with a fever, a toddler on your lap, or tears in your eyes—you’re not alone.

Sub plans shouldn’t be harder than teaching itself. That’s where AI comes in.

With free tools like ChatGPT or MagicSchool.ai, you can generate detailed, customized sub plans in minutes—no more scrambling, printing, or hoping your binder is up to date.
