AI Contract Analysis Platform: AI in Legal

Business Problem

The legal sector faces unique challenges that AI can address:

Manual clause identification is time-consuming and error-prone

Scale requirements exceed human capacity

Real-time decisions require instant processing

Consistency across operations is difficult to maintain

AI Contract Analysis Platform addresses these challenges using LLM + Extraction.

Implementation

Data Pipeline

python
from dataclasses import dataclass
from typing import Optional
import json
@dataclass
class LegalRecord:
    """Data record for legal AI processing."""
    id: str
    content: str
    metadata: dict
    source: str = "Document Review"
class DocumentReviewConnector:
    """Connect to Document Review data source."""
    
    def __init__(self, config: dict):
        self.config = config
    
    def fetch_records(self, query: dict = None) -> list[LegalRecord]:
        """Fetch records from Document Review."""
        # Implement API integration
        return []
    
    def transform(self, raw: dict) -> LegalRecord:
        """Transform raw data to structured record."""
        return LegalRecord(
            id=raw.get("id", ""),
            content=raw.get("content", ""),
            metadata=raw.get("metadata", {}),
        )

AI Processing Layer

python
from openai import AsyncOpenAI
class AIContractAnalysisPlatform:
    """AI Contract Analysis Platform using LLM + Extraction."""
    
    SYSTEM = f"""You are an AI expert in legal sector applications.
    Your task is clause identification.
    Provide accurate, actionable, and compliant outputs.
    Consider industry regulations and best practices."""
    
    def __init__(self, model: str = "gpt-4o"):
        self.client = AsyncOpenAI()
        self.model = model
    
    async def analyze(self, record: LegalRecord) -> dict:
        """Perform AI analysis on a legal record."""
        
        prompt = f"""Analyze the following legal data:

        response = await self.client.chat.completions.create(
            model=self.model,
            messages=[
                {"role": "system", "content": self.SYSTEM},
                {"role": "user", "content": prompt}
            ],
            temperature=0.1,  # Low temp for consistency
            max_tokens=1500
        )
        
        return {
            "analysis": response.choices[0].message.content,
            "record_id": record.id,
            "model": self.model,
            "industry": "Legal"
        }
    
    async def batch_analyze(self, records: list[LegalRecord]) -> list[dict]:
        """Process multiple records concurrently."""
        import asyncio
        tasks = [self.analyze(r) for r in records]
        return await asyncio.gather(*tasks)

API Service

python
from fastapi import FastAPI, BackgroundTasks
from pydantic import BaseModel
import asyncio
app = FastAPI(title="AI Contract Analysis Platform API")
processor = AIContractAnalysisPlatform()
class ProcessingJob(BaseModel):
    record_id: str
    content: str
    metadata: dict = {}
@app.post("/analyze")
async def analyze(job: ProcessingJob):
    record = LegalRecord(
        id=job.record_id,
        content=job.content,
        metadata=job.metadata
    )
    result = await processor.analyze(record)
    return result
@app.post("/batch")
async def batch_analyze(jobs: list[ProcessingJob]):
    records = [LegalRecord(
        id=j.record_id, content=j.content, metadata=j.metadata
    ) for j in jobs]
    return await processor.batch_analyze(records)

Integration with Document Review

python
Connect AI processing to Document Review
async def run_pipeline():
    connector = DocumentReviewConnector(config={})
    processor = AIContractAnalysisPlatform()
    
    # Fetch new records
    records = connector.fetch_records()
    
    # Process with AI
    results = await processor.batch_analyze(records)
    
    # Store/act on results
    for result in results:
        print(f"Processed {result['record_id']}: {result['analysis'][:100]}...")
    
    return results
