Elevator Pitch

PureFocus AI — Empower your productivity with offline, privacy-first AI-driven focus insights right inside Chrome.

Inspiration

In today's digital world, staying productive while browsing online is challenging, especially with privacy concerns around data sharing. PureFocus AI was inspired by the desire to combine cutting-edge AI-driven productivity insights with complete user privacy, leveraging Chrome’s built-in Gemini Nano model to run fully offline.

What it does

PureFocus AI tracks your browsing time across all sites and provides a personalized Focus Score and actionable insights. It suggests focused work blocks and highlights patterns that help improve your productivity, all while keeping your data private on your local device.

How we built it

Built as a Chrome extension using Manifest V3, PureFocus AI is developed with JavaScript, HTML, and CSS. It uses Chrome’s Extensions API and local storage for data management. The Gemini Nano on-device AI model analyzes user activity completely offline to generate real-time, personalized insights.

Challenges we ran into

Ensuring the Gemini Nano model processed insights efficiently while offline was challenging. Balancing privacy with meaningful AI feedback without external APIs required careful design of data storage, analysis, and UX. Creating motivating, concise advice was a creative challenge.

Accomplishments that we're proud of

  • Seamlessly integrated Gemini Nano AI for offline analysis
  • Developed a fully private, offline-first Chrome extension
  • Delivered personalized, actionable focus insights
  • Built an intuitive UI that encourages positive habits

What we learned

We deepened our understanding of Chrome extension APIs and on-device AI applications. We learned the importance of privacy-first design for user trust and how to optimize data handling for performance and responsiveness.

What's next for PureFocus AI

Future plans include weekly focus reports, streak tracking, motivational AI summaries, and enhanced AI scoring using contextual browsing data. We aim to maintain privacy while potentially incorporating optional hybrid AI features.
