Inspiration

Online shopping is designed to encourage quick decisions, and I wanted to build a tool that helps users pause and think before making impulse purchases.

What it does?

Impulse Guard is a Chrome extension that detects checkout pages and uses AI to give users a short financial reality check before they buy.

How we built it?

We built a Chrome extension connected to a secure Node.js backend that sends user context to the Gemini AI API for real-time advice.

Challenges we ran into

We faced issues with deprecated AI models, API security, and debugging Chrome extension message passing across different environments.

Accomplishments that we're proud of

We successfully built a full end-to-end AI system with a real backend, secure API handling, and a smooth user experience.

What we learned

We learned how to design real-world AI architectures, work with Chrome extensions, and integrate large language models securely.

What's next for Impulse Guard

We plan to make to user interaction more productive and work on finetuning on Gemini 3 response.
