Inspiration Shadow Omni is a privacy-first local AI assistant. It runs entirely on your device without using cloud APIs or internet
What it does It provides a secure environment for AI tasks using local hardware. It features a Security Shield with Master Key encryption and allows users to export or import their local AI "Brain" data.
How we built it We built the core using JavaScript and HTML5. We implemented client-side encryption for the Security Shield and created a local database management system that stays locked until authorized.
Challenges we ran into The main challenge was building a robust local encryption system within the browser. Managing data sovereignty and the Export/Import Brain features without any external server support was also difficult.
Accomplishments that we're proud of We are proud of achieving 100% data privacy. Creating an AI system that works offline and gives users full control over their encrypted data is our biggest win.
What we learned We learned that local-first development is the future of privacy. We discovered how to use browser storage and encryption to replace vulnerable cloud-based AI systems
What's next for SHADOW OMNI 8.5 We plan to integrate the Gemma-2B model directly into the browser using WebGPU for faster offline processing. Our goal is to expand the Security Shield to support multi-user local profiles with advanced biometric encryption. We will also refine the Export/Import Brain feature to allow seamless AI personality transfers across different devices while maintaining 100% data privacy. Finally, we aim to build a community-driven library of local-first plugins to prove that powerful AI does not need the cloud.
