Prompt Box

Store and organize your AI prompts

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.
