Juris AI

Overview

Juris AI is an intelligent legal assistant built to simplify complex legal contracts.
It leverages generative AI to break down dense legal language, highlight critical clauses, and provide actionable negotiation insights — all while maintaining a strong privacy-first architecture.

The platform is designed to assist users in understanding contracts, not to replace professional legal advice.

Note: All uploaded documents are processed ephemerally and are never permanently stored.

Data Flow & Privacy Model

User privacy and data security are central to Juris AI’s architecture.

End-to-End Data Flow

1. Authentication
   User securely logs in via Google OAuth or email/password.

2. File Upload
   User uploads a legal contract (PDF or DOCX) through the frontend.

3. Text Extraction & Temporary Storage

   • Backend extracts raw text from the document
   • Text is stored temporarily in Redis with a short TTL
   • Original file is immediately discarded

4. AI Analysis
   Extracted text is sent to the Gemini API for summarization and insights.

5. Result Delivery
   AI-generated summaries, highlighted clauses, and negotiation insights are returned to the user dashboard.

6. Automatic Data Deletion
   Redis entries are deleted immediately after successful processing.

Outcome

Juris AI demonstrates a privacy-first, AI-driven document analysis system, combining secure file handling, ephemeral data storage, and structured AI outputs to make legal contracts more accessible and understandable.
