Prompt library with folders, fill-in variables and one-click insertion into ChatGPT, Claude and other AI chats
PromptBox stores your prompts in organized, shareable folders and gets them back into AI chats fast: one-click insertion, fill-in-the-blank variables that ask for input at use time, clipboard wrapping for copied text, and a desktop shortcut expander that turns a typed abbreviation into a full prompt in any app. It ships as a browser extension plus web app. Listed as 'Prompt Box' in some directories, the product now runs $5.99/month after a 14-day trial, with a $79 lifetime license — figures we read from the site's own application code, since the public homepage renders as a bare shell without marketing or pricing pages.
In-app plan markup shows Monthly at $5.99 with a 14-day free trial and a Lifetime option at $79. The site no longer renders a public pricing page, so tiers may change without notice; older listings describing a free tier could not be confirmed.
Use tool ↗Covers the core prompt-hoarder needs well — folders, shared libraries, variables and shortcut expansion that works outside the browser. The concern is the company's quiet public face: a homepage that renders empty and no visible docs make this a small-tool bet, best taken on the monthly plan rather than the lifetime license.
