Prompt Vault

Q: Where are my prompts saved?

Strictly on your device. We use IndexedDB for persistent browser-based storage. Zero data is sent to our servers, ensuring your enterprise or personal prompts remain 100% private.

A local, privacy-first AI prompt manager. Organize your ChatGPT, Claude, and Gemini prompts securely in your browser with variables and one-click copy.

Support Applied AI Hub

I'm a solo dev building these tools to be fast and private. If they saved you some time, consider buying me a coffee to cover server costs!

This site uses no tracking cookies or intrusive ads. Your support helps keep it that way.

Zero-Server Privacy: Other prompt managers sync your IP to the cloud. Our Prompt Vault uses native IndexedDB to keep everything saved locally on your device. Your sensitive enterprise prompts and API keys never touch our servers.

How to Use Variable Injection

Writing highly adaptable prompts is key to mastering AI. Instead of manually editing long text blocks, use our injection syntax:

Step 1: Type Write a {{tone}} email to {{name}} about {{topic}}.
Step 2: When you click copy, a side-by-side overlay appears.
Step 3: Fill in the values on the left while watching the Live Preview reconstruct the prompt in real-time on the right.
Step 4: Click "Copy & Open" to push the perfect text into your preferred AI.

Frequently Asked Questions

Where are my prompts saved?

Strictly on your device's local storage. Not a single byte of your prompt data is ever transmitted to a backend API, making this 100% compliant with corporate NDA usage.

Can I use the app offline?

Absolutely. Once the site is cached, the Vault is completely serverless. You can edit, tag, and export your prompts on an airplane.

Why are you adding specific AI model links?

Every foundation model has strengths. You might use DeepSeek for coding, Claude for creative writing, and Gemini for web searches. The Prompt Vault acts as an agnostic command center to bounce your prompt out to the most suitable model dynamically.
