What does PromptCrate do?

It is a personal prompt manager and library. Save the AI prompts that work for you, organize them by category, and reuse them in ChatGPT, Claude, Gemini and any AI chat app — without rewriting the same instructions each time.

How do fill-in templates work?

Wrap the changing parts of a prompt in double braces, like {{topic}} or {{tone}}. PromptCrate turns each placeholder into an input field, then assembles the finished prompt for you with no manual editing.

Do I need an account?

No. Your prompts are stored locally on your device. PromptCrate does not require an account to build and manage your prompt library, and it works offline.

PromptCrate is free to use. An optional one-time Pro upgrade unlocks premium prompt packs, unlimited saved prompts and an ad-free experience, with no recurring charge.
