# What is a prompt library? > A prompt library is a shared, organized set of prompts that work, so a whole team can reuse them. How to start one and keep it useful, with an example.

It lets a whole team reuse what works instead of each person improvising their own requests. ## Why it matters for a small business In most small businesses, one person figures out a prompt that makes meeting recaps or customer replies easy, and nobody else knows it exists. A library turns that private trick into a shared tool. New hires get good results on day one, and the owner can see what the business is actually asking AI to do. A library is also where you keep the safety rules that matter. If your best recap prompt says to write "Not stated" instead of guessing a date, everyone who copies it inherits that protection. Without a library, each person rewrites the prompt from memory and the careful parts are the first to disappear. ## In a real lesson: Turn a Client Meeting into Action Items and a Follow-Up Email (Accounting Firms) In [Turn a Client Meeting into Action Items and a Follow-Up Email](https://learn.ynteractive.com/content/chatgpt-client-meeting-recap-accounting-firm), Millbrook Accounting (a made-up firm) reviews Q3 with its client Cedar Lane Landscaping. You click **Paste request** to ask for a three-sentence summary, the decisions, an action items table (task, owner, due date) and open questions, ending with: if an owner or date isn't said, write "Not stated". The lesson's closing advice is to keep that request handy for your next review or planning meeting. It also shows a second, shorter version for when the transcript arrives as a file: you click **+**, then **Add photos & files**, attach **Cedar Lane Q3 review - Transcript.docx**, and paste a one-line request asking for the same things. Those two versions, plus the follow-up email request, are exactly the kind of set worth filing together under one heading such as "Client meeting recap".

A library is the organized collection of templates, plus the names, notes and ownership that make them findable and trustworthy. ### Prompt library vs Custom GPT A library holds prompts people copy into any tool. A [Custom GPT](https://learn.ynteractive.com/content/glossary/custom-gpt) bakes one set of instructions into ChatGPT for one job. Many teams keep both: the library for many small tasks, GPTs for the few they do daily. ## Tips - Name entries by the job ("Client meeting recap"), not by the tool, so people can find them. - Add one line under each prompt saying what to check before using the output (owners, dates, prices). - Give the library an owner who removes prompts that stop working or no longer match your policies. - Never store client data inside a library prompt; keep the blanks blank. ## Related terms [Prompt template](https://learn.ynteractive.com/content/glossary/prompt-template) · [Prompt](https://learn.ynteractive.com/content/glossary/prompt) · [AI summarization](https://learn.ynteractive.com/content/glossary/ai-summarization) · [Action items](https://learn.ynteractive.com/content/glossary/action-items) · [AI acceptable use policy](https://learn.ynteractive.com/content/glossary/ai-acceptable-use-policy) ## Where you use it: free lessons - [Turn a Client Meeting into Action Items and a Follow-Up Email (Accounting Firms)](https://learn.ynteractive.com/content/chatgpt-client-meeting-recap-accounting-firm) (ChatGPT, 9 min) - [Prompt Writing 101: Role, Context, Task, Format](https://learn.ynteractive.com/content/prompt-writing-101-role-context-task-format) (ChatGPT, 8 min) - [Summarize a Meeting Transcript with ChatGPT](https://learn.ynteractive.com/content/chatgpt-summarize-meeting-transcript) (ChatGPT, 9 min) ## Frequently asked questions **What tool should I use for a prompt library?** Start with what your team already uses daily, like a shared Google Doc or wiki page. Move to something fancier only if finding prompts becomes a problem. **How many prompts should a small business library have?** Start with the five to ten tasks you repeat most. A short list people actually use beats a long one nobody opens.
