About Prompt Box
Prompt Box: Your Personal AI Prompt Library + Text Expander
You've typed your email address 10,000 times. You've rewritten the same intro email from scratch, again. You've lost your best AI prompt because you forgot to save it.
Prompt Box fixes all of that in one install. It combines a personal AI prompt library with a text expansion engine, so anything you type repeatedly becomes a one-trigger shortcut.
⚡ TEXT EXPANSION: TYPE LESS, DO MORE
Give any saved prompt or snippet a short trigger. Type the trigger in any text field and it expands into the full text.
A few examples:
• /email → your email address
• /sig → your full email signature
• /intro → your go-to introduction paragraph
• /thanks → your post-meeting thank-you note
• /code → your most-used code snippet
Type the trigger. Blink. Done.
✨ FEATURES
Text Expansion
Type a trigger and press Space, Tab, or Enter to expand it in any text field on any site. On sites that block expansion, Prompt Box copies the text to your clipboard and shows a reminder so you can paste it in one keystroke.
Quick Save
Highlight text on any page, right-click, and choose "Save to Prompt Box." Capture a great prompt, template, or snippet without breaking your flow.
One-Click Copy
Open Prompt Box, click any saved item, and it's on your clipboard.
Tags and Categories
Organize with custom tags and built-in categories. Create tags inline while saving, or manage them in Settings.
Search, Filter, and Sort
Find anything instantly by keyword, tag, title, date added, or favorites.
Favorites
Star your most-used items so they surface first.
Chrome Sync or Local-Only Storage
Sync your library across Chrome profiles signed into the same Google account, with no extra account needed. Or keep everything on one device. Switch any time in Settings.
Import and Export
Back up your library to CSV, or import a spreadsheet to bulk-load prompts.
Full Editing
Rename, retag, update, or delete anything at any time.
☁️ PROMPT BOX PRO (OPTIONAL)
Sign in with Google and turn on Cloud sync to keep your prompts in sync across browsers and devices, offline-first. Cloud prompts are end-to-end encrypted with a sync passphrase only you know, so nobody else can read them, including us.
Pro is available monthly ($2.99/mo), annually ($19/yr), or as a limited Founding Lifetime plan ($39 once). Payment is handled entirely on Stripe's secure checkout page; the extension never sees your card details.
🔒 LOCAL-FIRST BY DEFAULT
• Stored in Chrome's secure extension storage
• No tracking, no analytics, no ad data sharing
• Survives browser cache clears
• By default, the only thing that leaves your device is Chrome's own built-in sync. Choose Local-only in Settings to keep everything on one device.
• Uninstalling permanently deletes stored data, so export to CSV first
💡 HOW IT WORKS
Save a prompt:
1. Highlight text on any page
2. Right-click and choose "Save to Prompt Box"
3. Click the extension icon to browse and copy
Set up an expansion:
1. Save text you type often
2. Give it a trigger, like /email
3. Type the trigger in any text field and it expands
No setup and no account needed. Install it, save your first prompt, and set your first expansion in under a minute.
