Inspiration

My inspiration comes from the constant and growing use of AI Chatbots

What it does

Meet Promptify, your personal AI Prompt Engineer — a Chrome extension that refines any prompt into a powerful, clear, and effective version for AI models like ChatGPT, Gemini, and Claude.

What it does: Promptify takes your raw idea or question and instantly transforms it into a ready-to-use prompt that gets the most intelligent and creative responses possible.

How we built it

How We Built It 1. Setup: Created a Manifest V3 Chrome Extension with HTML, CSS, and JavaScript in VS Code. 2. UI Design: Built a sleek popup interface (popup.html, popup.css) for input, refinement, and output. 3. Core Logic: Implemented the popup.js script that: • Sends user text to the AI • Uses a system prompt that defines Promptify’s role as an expert prompt engineer. 4. Extras: Added a right-click “Refine with Promptify” option, local storage for history, and an “About” page for branding. 5. Testing & Optimization: Tested via Chrome’s Developer Mode

Challenges we ran into

Accomplishments that we're proud of

Designed a custom system prompt that turns Promptify into an expert AI prompt engineer, capable of rewriting any rough user input into a clear, effective, and ready-to-use AI prompt, optimized for models like ChatGPT, Gemini, and Claude.

What we learned

1.Develop and structure a Chrome Extension (Manifest V3) from scratch using HTML, CSS, and JavaScript. 3.Combine good UX design and AI engineering, turning a simple idea into a real, polished productivity tool.

What's next for Promptify

Integrate directly with Gemini Nano once it’s fully available, enabling real on-device AI rewriting.

Add multiple rewrite modes (Creative, Formal, Concise, Summarize) and a history tab for past refinements.

Launch Promptify on the Chrome Web Store, making it accessible to everyone who writes or engineers prompts.

Expand beyond Chrome — bringing Promptify to Edge and Firefox as AI-powered writing assistants
