At 16, I Developed an AI Browser with Advanced Prompt-Injection Defense on an i5 with 8GB RAM

Introducing Comet AI Browser: A Game Changer in Browsing Security

Hey LinkedIn! I’m Preet, a 16-year-old developer passionate about AI technology. Over the past two months, I’ve created Comet AI Browser, a revolutionary cross-platform tool designed to enhance security while browsing.

What Comet AI Browser offers:

  • Innovative Security Architecture: Enforces isolation at the system level, preventing prompt injection.
  • Syntactic Firewall: Strips dangerous commands before reaching the AI.
  • Multi-provider AI Routing: Integrates various AI engines including GPT and Claude for enhanced capability.
  • Cross-Device Sync: Control your desktop from your phone seamlessly.

What it’s not:

  • Not production ready—currently a beta with some known issues.
  • Built on Electron and Next.js, with plans for a native Chromium integration.
