Prompt Vault

A simple Chrome extension for storing, organizing, and reusing text prompts. Save prompts with titles and tags, then copy them to your clipboard in one click. Supports #variable# placeholders that get filled in via a modal before copying.

Warning

Obviously, this is NOT a password manager. DO NOT use it to store any sensitive data (passwords, credit card numbers, API keys, etc.)

Tip

What you can use it for instead:

• LLM Prompts
• Regular Expressions
• bash commands
• ... basically, anything too complex or lengthy to remember and that you want to access in 2 clicks

Features

• Save & organize prompts with titles and comma-separated tags
• Fuzzy search across prompt titles, bodies, and tags (powered by Fuse.js)
• Tag filtering to browse prompts by category
• Variable substitution: use #variableName# in any prompt and fill values in at copy time
• Right-click to save: select text on any webpage and save it as a new prompt via the context menu
• Import / Export: back up and restore your prompts as a JSON file

Usage

1. Click the extension icon to open the popup.
2. Click New to create a prompt. Give it a title, body, and optional tags.
3. Click any prompt card to copy it. If it contains #variables#, a modal will ask you to fill them in first.
4. Use the search bar or tag dropdown to filter your prompts.
5. Right-click any selected text on a page and choose "Save as Prompt" to pre-fill the form.

Variable syntax

Wrap placeholder names in # signs inside a prompt body:

For example when you click this prompt, you'll be asked to fill in the variables broad_topic, target_group, country, and language before the final prompt is copied.
