HOW A SAVED PROMPT BEHAVES

A prompt with blanks in it is a template

Anything you wrap in curly braces becomes a blank. This one is Blog Post Outline, straight out of the built-in library: three blanks, one prompt, a different brief every time you use it.

Prompt variables, and how to write them
Saved once

Write a detailed blog post outline about {topic} for an audience of {audience}. Include an attention-grabbing intro, 5 main H2 sections with 2-3 H3 subsections each, key points to cover under each, and a conclusion with a clear call-to-action. Tone: {tone}.

  • topic sourdough starter maintenance
  • audience first-time bakers

Write a detailed blog post outline about sourdough starter maintenance for an audience of first-time bakers. Include an attention-grabbing intro, 5 main H2 sections with 2-3 H3 subsections each, key points to cover under each, and a conclusion with a clear call-to-action. Tone: warm and practical.

Paste it wherever you were going to type it. PromptVault does not talk to any AI service, and is not connected to or endorsed by one.

The rest of it

One tap to copy

A prompt with no blanks goes straight to the clipboard. One with blanks opens the fill sheet first. Either way it is two taps from opening the app to pasting.

Folders, categories and tags

Make your own folders, file each prompt under one of eight categories, and add as many tags as you like. The chips across the top of My Prompts filter by either.

Search that reads the body

Type and the list narrows as you go, matching the title, the description, the full prompt text and the tags — not just the name you gave it eight months ago.

Favourites and recently used

Star the handful you reach for daily and they sit on the home screen. The six most recently copied sit above them, in the order you last used them.

Export to a JSON file

Write the whole collection out as one JSON file you can keep anywhere, and read it back in on a new phone. Part of the $4.99 unlock.

Light, dark, or whatever the phone says

A three-way theme setting. The prompt body renders in a monospaced face in both modes, with the blanks picked out in blue so they are easy to spot.

Why it is worth keeping

  • Nothing leaves the phone. Prompts live in a local database. No server holds them.
  • No account, no sign-in. Install it and start pasting prompts in.
  • Model-agnostic by design. It is a text store. Whichever assistant you move to next, the prompts come with you.
  • Saved prompts are never taken away. Reach the fifty-prompt cap and the ones you have stay readable and copyable.
  • Ten languages. English, Spanish, French, German, Portuguese, Hindi, Arabic, Japanese, Korean and Chinese.
  • One payment, not a subscription. $4.99 unlocks it and nothing renews.

Questions

Does PromptVault send my prompts to ChatGPT, Claude or Gemini?

No. It is not connected to any AI service and has no affiliation with one. It copies the finished text to your clipboard and you paste it into whichever assistant you use.

How do the variables work?

Write {topic} or {audience} anywhere in a prompt. When you copy it, PromptVault asks for each one, shows a live preview, and puts the filled version on the clipboard.

How many prompts can I keep before the unlock?

Fifty of your own. After that, new prompts need the $4.99 unlock. Prompts you already saved are never locked, hidden or deleted, and the built-in library stays readable.

What is in the built-in library?

Fifty-five ready-made prompts across eight categories: Business, Marketing, Coding, Creative, Writing, Analysis, Education and Image Generation. Save any of them and edit the wording.

Does it work offline, and do I need an account?

It works offline and there is no account. Everything sits in a database on the phone. A connection is only used to serve ads before you buy the unlock.

Is it a subscription?

No. $4.99 once, through Google Play. Nothing renews.

Put the good ones somewhere
