Where should you actually keep your prompts?
Notion, Obsidian, or a plain folder of text files? The honest answer is "the one you already use" — but here is how to choose well, and why the app matters far less than you think.
Every few weeks someone asks the same reasonable question: what is the best app for storing prompts? And the honest answer is a little anticlimactic — the best place is the one you already open every day. The app is not the hard part. The habit is. Still, the three common homes each have a personality worth matching to yours.
Plain Markdown files
A folder of `.md` files is the most durable option there is. No account, no lock-in, no company that can change its pricing or shut down. Your library is just text you own, syncable with anything, readable in fifty years.
- Best for: people who value ownership and portability above all.
- Trade-off: search and linking are only as good as your editor.
- The vibe: quietly permanent.
If you are unsure, start here. You can always import plain files into a fancier tool later; going the other direction is harder.
Obsidian
Obsidian sits on top of plain Markdown files, so you keep the ownership — but gain fast search, backlinks between related prompts, and a graph of how your library connects. For a personal prompt library that grows over time, it is a lovely fit.
- Best for: solo builders with a growing, interconnected library.
- Trade-off: a little setup; overkill for ten prompts.
- The vibe: a personal workshop.
Notion
Notion shines the moment other people are involved. Databases, shared permissions, and templates make it the natural home for a team standard. If your prompt library needs to be something a teammate can browse on day one, Notion earns its place.
- Best for: teams and anyone who thinks in databases.
- Trade-off: it is an account you log into, not a file you own.
- The vibe: the shared library.
Whatever you choose, keep the one hard rule: a library, not a keychain. None of these tools is the right place for an API key or private customer data. Store the prompt; reference the secret from a real secrets manager.
The part that actually matters
Notice what did not change across all three options: the folder structure and the naming pattern. A prompt named `editor · tighten prose · keep voice` is just as findable in a plain folder as in Notion. That is the whole point — the method travels, so you are never trapped by a tool.
So pick the home that fits your life today, knowing you can move later without losing anything. Then spend your energy on the part that compounds: organizing the prompts themselves. If you want the structure ready-made, the free Quick-Start Sheet drops straight into any of the three.
The folder structure and five templates — ready to paste into whichever home you pick.
Where Should You Actually Keep Your AI Prompts?: FAQ
Can I switch tools later without losing everything?
Yes — as long as you keep your prompts as text and your naming pattern consistent. Plain Markdown moves into Obsidian or Notion cleanly. That portability is exactly why the method matters more than the app.
Which is best for a team?
Notion, most of the time. Shared permissions and databases make a team standard easy to browse and maintain. Keep the "no secrets" rule strict when a library is shared.
Is it worth paying for an app just to store prompts?
Rarely. Start free with plain files or the free tier of a tool you already use. Upgrade only when you feel genuine friction — not before.
