Inspiration

Privacy policies are opaque legal documents that most users ignore. I saw an opportunity to leverage browser-based AI to decode these complex texts, making data handling practices transparent and accessible to everyone.

What it does

Legal AI analyzes privacy policies in real-time, providing risk assessments across key privacy dimensions. The extension breaks down complex policies into clear explanations and concrete findings, displayed in an intuitive side panel.

How we built it

• Chrome Extensions Manifest V3 framework
• Gemini Nano for local AI processing
• GPT Tokenizer for efficient text chunking
• Preact for lightweight UI components
• Radix for accessibility-first components
• Tailwind CSS for robust styling

Challenges we ran into

• Optimizing Gemini Nano for browser performance
• Cleaning webpage text extraction from diverse structures
• Crafting effective prompts for concise yet thorough analysis
• Managing token limits through parallel chunk processing

Accomplishments that we're proud of

• Built a completely local, privacy-respecting analyzer
• Achieved reliable risk assessments with small LLM
• Created an accessible, user-friendly interface
• Maintained speed while processing large documents

What we learned

• Modern Chrome Extension architecture
• Privacy-centric application design
• Legal document parsing techniques
• Small LLM optimization for complex analysis

What's next for Legal AI
