Prompt Librarian

Every prompt you've written, kept somewhere you can find it again.

A native Mac app that catalogs your AI prompts as plain Markdown: tagged, searchable, and ready to fill in without touching the original.

Good prompts get written once and lost twice: buried in a chat history, then rewritten from memory the next time you need one.

Prompt Librarian is the one place they live instead.

What it does

Folders, tags, and favorites
Organize prompts the way you actually think about them, not the way a database wants you to.
Markdown, natively
A formatting toolbar and a live-rendered preview, in the format your prompts already use.
Variables, without touching the original
A guided wizard walks through each {{placeholder}} in a prompt and fills it in on a copy. The saved version stays exactly as written, ready to reuse the next time the details change.
Saved autofill values
Keep the names, dates, and phrases you type constantly. Insert them into a variable with one click.
Fuzzy search and filters
Find a prompt by tag, favorite, or a few loose keystrokes; no exact titles to remember.
Multiple tabs
Keep several prompts open and editable side by side.
Import existing prompts and in bulk from CSV
Add your own prompts, or bring an existing spreadsheet of prompts in all at once, mapped to titles, content, and categories.
Copy, clean
What lands on your clipboard is pure Markdown; no invisible styling riding along into your AI tool of choice.
No subscriptions, ever
Buy it, own it. Purchase and it's yours forever.

Your prompts, as files you already own

Every prompt is stored as a plain .md file, in a folder you choose. No proprietary format, no account, no server holding your library hostage. If Prompt Librarian disappeared tomorrow, your prompts would still open in any text editor.
