LexAI

Purpose: LexAI is a macOS application that helps people in the United States navigate legal information when they struggle with English as their primary language. The application provides an accessible way for non-English speakers to understand legal information, ask questions about their rights, and analyze legal documents in a language they are comfortable with. It also provides an intuitive interface, document handling, and multilingual support that could assist legal professionals with their clients.

Functionalities:

1. Sidebar Navigation System - Users can easily navigate between different sections of the app including new chat sessions, chat history, document upload, and settings using SideBarView.swift.

2. Chat Interface - Users can ask legal questions and receive AI-generated responses. The chat supports session handling, clearing chat history, and saving conversations using ChatView.swift.

3. Multilingual Translation Pipeline - Responses are automatically translated to support non-English users, making legal information accessible across language barriers.

4. Legal Document Upload & Processing - Users can scan and upload documents (such as lease agreements, court notices, or legal forms) using parse_pdf.py for text extraction and analysis.

5. Michigan Legislation Data Retrieval - The app fetches and structures real legislation data from Michigan using external APIs, storing results in JSON format (bill_text.json, bill_details.json).

6. Data Chunking for Processing - Legal text is split into smaller, manageable segments using chunk_text.py to enable efficient embedding and AI processing.

7. Legal Disclaimer on First Launch - A disclaimer (disclaimer.swift) informs users that LexAI is not a substitute for professional legal advice.

8. Firebase Authentication & Backend - User authentication and backend services are supported through Firebase integration.
