A sophisticated legal tech platform designed to demystify Indian law for freelancers, SMBs, and legal professionals.
Built for Gen AI Hackathon 2025 by Google Cloud & Hack2Skill
IndiaLawAI leverages multi-modal generative AI to score documents for compliance, identify risks in multiple languages, and provide actionable insights, turning complex legal jargon into clear, measurable data.
This tool moves beyond simple analysis by introducing the "IndiaLaw Score," a proprietary metric that quantifies a document's compliance with Indian regulations.
-
AI-Powered Compliance Scoring: Instead of a simple pass/fail, IndiaLawAI generates a quantifiable IndiaLaw Score (0-100), with a detailed breakdown across key legal categories like Labor Law, GST, and Contractual Obligations. This allows users to track compliance improvements over time.
-
Intelligent Multilingual Document Analysis:
- Seamless Translation: The app supports English, Hindi, Tamil, Bengali, and Marathi end-to-end. Users can upload documents and receive analysis in their native language.
- Advanced OCR: Utilizes Google Gemini AI for high-accuracy text extraction from complex documents, including scanned PDFs and images in multiple languages.
-
Interactive Q&A: Engage in a natural language conversation with your legal documents. Ask specific questions ("What is the notice period required by this contract?") and receive precise, AI-powered answers with references to the relevant clauses.
-
Smart Multilingual Responses: Ask questions in any supported language and receive answers in the same language, keeping legal terminology intact.
-
Real-time Risk Translation: Instantly translate compliance risks and recommendations based on selected language while preserving legal citations.
-
Export & Reporting:
- Download comprehensive multilingual PDF reports
- Email reports via secure backend service
- Professional analysis exports with citations
-
Secure User Authentication: Full authentication system powered by Firebase Auth, supporting both Google Sign-In and traditional email/password, ensuring user data and analysis history are secure.
-
Persistent Data Storage: All documents and analyses are securely stored in Cloud Firestore with real-time synchronization across devices.
-
Responsive Design: Fully responsive mobile-first interface that works seamlessly on phones, tablets, and desktops.
This application is built with a modern, robust, and scalable tech stack, carefully chosen to deliver a high-performance and feature-rich experience.
- Framework: React 18 with TypeScript for building an interactive, type-safe user interface
- Language: TypeScript for strong typing and improved code quality
- Styling: Tailwind CSS for a utility-first, consistent design system
- Build Tool: Vite 5 for lightning-fast development and optimized production builds
- Internationalization: i18next for comprehensive multilingual support
- Language Model (LLM): Google Gemini 2.5 Flash is the core AI model for all analytical tasks, including compliance analysis, summarization, Q&A, and translation
- Optical Character Recognition (OCR): PDF.js for client-side PDF text extraction combined with Google Gemini Vision for images and scanned documents
- Authentication: Firebase Authentication for secure user management (Google & Email/Password)
- Database: Cloud Firestore for storing user data, documents, and analyses with real-time updates
- Offline Support: IndexedDB Persistence for offline document access
- Deployment: Production-ready build system with optimized bundle sizes

Follow these steps to set up and run the project locally.
- Node.js (v18 or later)
- A Firebase project with Authentication, Firestore, and Storage enabled
- Gemini API key from Google AI Studio
Create a .env file in the root of the project with the following variables:
# Firebase Configuration
VITE_FIREBASE_API_KEY=your_firebase_api_key_here
VITE_FIREBASE_AUTH_DOMAIN=your_project_id.firebaseapp.com
VITE_FIREBASE_PROJECT_ID=your_project_id
VITE_FIREBASE_STORAGE_BUCKET=your_project_id.appspot.com
VITE_FIREBASE_MESSAGING_SENDER_ID=your_messaging_sender_id
VITE_FIREBASE_APP_ID=your_app_id
# Google AI Services
VITE_GEMINI_API_KEY=your_gemini_api_key_here- In your Firebase project console, go to Authentication > Settings > Authorized domains and add the domain of your development environment (e.g.,
localhost). - Enable Email/Password and Google sign-in methods in Firebase Authentication
- Create a Firestore database in Production mode or Test mode
- Copy your Firebase configuration values from the Firebase console and add them to your
.envfile
Install the necessary packages using npm:
npm installStart the Vite development server:
npm run devOptional: Start the email server in a separate terminal for email functionality:
npm run email-serverThe application will be available at http://localhost:5173. You will be prompted to log in or sign up before you can access the analysis workbench.
