A prompt library is just a document where you save prompts that have worked well, organized by the teaching situation they’re useful for. Building one takes about five minutes per week and pays off every time you sit down to prepare a live session.
Why a Prompt Library Reduces Live Anxiety
Tech anxiety in live sessions often comes from uncertainty about what to type. When you’re on-screen, thinking of a good prompt while also facilitating a group is genuinely hard. A prompt library solves that by pre-deciding your prompts before the pressure is on. When you open your session notes and see your prompts already written and tested, a significant portion of live AI anxiety disappears — because the hardest part is already done.
Think of it like a chef who preps their mise en place before service. The cooking itself is still creative and responsive, but the fundamental ingredients are already measured and ready. Your prompts are your mise en place.
How to Structure Your Prompt Library
The most useful organization is by session moment, not by topic. Create sections for: opening hooks (AI-generated provocations to start a class), discussion generators (prompts that produce three to five discussion questions on any topic), live Q&A support (prompts that help you respond to tricky student questions), session summaries (prompts that produce a clean recap of what was covered), and follow-up activities (prompts that generate homework or practice tasks). Within each section, save the exact prompt text that has worked, a note on what context it needs, and the date you last tested it.
Start with one prompt per section — five prompts total. Test each one in a real session. After four weeks you’ll have a working library of ten to fifteen battle-tested prompts. After a term, you’ll have enough to walk into any session type with your AI moments already planned.
What This Means for Educators
Your prompt library becomes your most valuable prep asset over time. Unlike lesson plans that go stale, a good prompt library compounds — each new session adds prompts, and each tested prompt reduces your prep time for the next one. Educators who build this habit early find that AI session prep eventually takes less time than sessions without AI used to.
The Simple Rule
After every session where AI worked well, save that prompt immediately. Don’t wait. Copy it into your library before you close the tab. The best prompts are lost to closed browser windows every day.
