Where people keep AI prompts
Five honest options, including doing nothing. Most people are on the first one and it is working fine until it suddenly is not.
Updated September 2026
Every option below is a real system that real people run. The question is not which is best, it is which one breaks first for the way you work.
A notes app
Works because: Zero setup, always open, syncs everywhere. For under about twenty prompts this is genuinely fine and you should not replace it.
Breaks because: There is no structure, so finding one means scrolling or searching for words you may not remember. And a prompt is stored whole, so reusing half of it means editing the other half every time.
A Notion database
Works because: Real structure. Tags, properties, filtered views, and it scales past a few hundred rows without falling over.
Breaks because: It asks you to file things. Every prompt needs a title, a tag, a category, and that upkeep is what people quietly abandon around week three. Copying a prompt out is also several clicks away from the tool you are actually working in.
A scratch file
Works because: Fast, local, in your editor, versioned if you want it to be.
Breaks because: One long file becomes unsearchable at exactly the point it becomes valuable, and it is on one machine unless you do the work to make it otherwise.
The tool's own saved prompts
Works because: Closest to the point of use. One click from the composer.
Breaks because: It lives inside that product. Switch models next year, which everyone does, and your library does not come with you. It is also usually flat, with no way to reuse a piece of a prompt.
A prompt library
Works because: Built for retrieval rather than filing. Prompts break into reusable chunks, so the parts that never change stop being rewritten.
Breaks because: It is another place to keep something, and it earns that only if you are reusing prompts often enough to feel the cost. If you write a prompt once and never return to it, you do not need one.
How to tell which one you need
Think of the one prompt you would hate to lose. Open whatever you use now, find it, and time yourself.
Under ten seconds, your system works. Near a minute, you do not have a system, you have a place things go.
The number that matters is not how many prompts you have kept. It is how long it takes to reach the one you want. The four-part method works in any of these tools, including the notes app you already have open.
