About

[What is PromptBox?]
PromptBox is a prompt companion designed for frequent users of AI tools such as ChatGPT, Claude, Midjourney, Copilot, and more. 
As we use AI more in our daily work, managing a growing library of prompts can become overwhelming. PromptBox solves this by providing a persistent "prompt arsenal" right in your browser's side panel. It allows you to store, organize, and dynamically fill prompts without ever leaving your current working tab.

[Why Should You Install PromptBox?]
1. No More Tedious Copy-Pasting: One-Click Smart Injection
Say goodbye to the "open notepad -> copy -> switch tab -> paste" routine. PromptBox automatically detects the active text input area on the webpage. With just a single click on the insert button, your prompt is instantly injected.

2. Bring Your Prompts to Life: Dynamic Variables & Smart History
Static prompts can be rigid. PromptBox supports dynamic placeholders like {{topic}} or {{tone}}. When inserting a prompt, it automatically extracts these variables and presents a quick form. Even better, it remembers your previous inputs, allowing you to select historical values from a dropdown menu in a split second.

3. Zero-Disruption Collection: Right-Click to Capture Inspiration
Stumble upon a brilliant prompt or a great piece of text while browsing? Simply highlight it, right-click, and select "Add to PromptBox" to save it to your personal library instantly—all without disrupting your reading flow.

4. Minimalist Side Panel Design: Clean & Focused
By utilizing the native Chrome Side Panel, PromptBox stays accessible without blocking your active web workspace. It features global fuzzy search and tag-based filtering, helping you find exactly what you need in seconds.

5. Secure Cloud Sync via Firebase
Powered by Firebase Auth and Firestore, your data is securely stored and synced in real-time. Whether you are working on your office desktop or home laptop, your personal prompt library is always up-to-date.

[Key Features]
- Persistent Side Panel: Always ready when you need it, featuring search and tag filtering.
- Dynamic Variable Filling: Support for {{variable}} syntax with autocomplete history dropdowns.
- Smart Injection: Auto-detects and inserts text directly into active input fields on target pages.
- Context Menu Saving: Quick right-click option to save webpage selections.
- Cloud Synchronization: Real-time multi-device database syncing.
- Quick Management: One-click raw copy, fast edit, and secure deletion for every card.

PromptBox is built to streamline your AI workflows and make prompt management straightforward.
