Legal Case Management Systems: Recreating Secure UIs with AI

TL;DR: Replay leverages AI to reconstruct secure and functional legal case management UIs directly from video recordings of user flows, offering a faster and more behavior-driven approach compared to traditional screenshot-to-code tools.

Legal case management systems (LCMS) are notoriously complex. They demand robust security, intuitive workflows, and meticulous data handling. Developing or updating these systems is often slow, costly, and prone to errors. Existing UI generation tools often fall short, failing to capture the dynamic behavior and nuanced interactions required for a truly functional system.

The Challenge: Reconstructing Complex UIs from Scratch#

Building a legal case management system UI is a significant undertaking. You need to consider:

• •Data Security: Protecting sensitive client information is paramount.
• •Workflow Optimization: Streamlining processes for lawyers, paralegals, and staff.
• •Compliance: Adhering to legal and regulatory requirements.
• •Scalability: Accommodating growing case volumes and user bases.

Traditional development methods often involve manual coding, UI design from scratch, or relying on screenshot-to-code tools that lack behavioral understanding. This results in:

• •Time-consuming development cycles
• •High development costs
• •Difficulty in maintaining consistency across the UI
• •Limited ability to adapt to changing legal requirements

Behavior-Driven Reconstruction: A New Paradigm#

Replay offers a revolutionary approach: behavior-driven reconstruction. Instead of relying on static screenshots, Replay analyzes video recordings of user interactions within a legal case management system. By understanding the intent behind each action, Replay generates working code that accurately reflects the desired functionality and user experience. This approach is powered by Gemini, allowing for intelligent interpretation of complex UI interactions.

Replay provides several key advantages:

• •Video as Source of Truth: Captures the dynamic behavior of the UI, including animations, transitions, and data updates.
• •Behavior Analysis: Understands user intent and generates code that reflects the desired functionality.
• •Faster Development: Reduces development time by automating the UI reconstruction process.
• •Improved Accuracy: Minimizes errors by accurately capturing the nuances of user interactions.
• •Enhanced Collaboration: Facilitates communication between developers, designers, and legal professionals.

Replay in Action: A Legal Case Management Example#

Let's consider a scenario where we need to recreate the UI for a specific workflow within a legal case management system: adding a new document to a case file.

Step 1: Recording the Workflow#

Record a video of a user demonstrating the process of adding a new document to a case file. This should include:

1. •Navigating to the case file.
2. •Clicking the "Add Document" button.
3. •Selecting the document from the file system.
4. •Adding metadata (e.g., document type, date, description).
5. •Saving the document.

Step 2: Uploading the Video to Replay#

Upload the recorded video to Replay. Replay will analyze the video and identify the key UI elements and interactions.

Step 3: Reviewing and Refining the Generated Code#

Replay generates code that reflects the recorded workflow. You can review and refine the code to ensure it meets your specific requirements. This might involve:

• •Adjusting the styling of the UI elements.
• •Modifying the data handling logic.
• •Adding security measures.

Step 4: Integrating the Code into Your LCMS#

Integrate the generated code into your legal case management system. Replay supports various frameworks and technologies, making integration seamless.

Code Example: Document Upload Component#

Here's an example of the code that Replay might generate for a document upload component:

typescript
// DocumentUpload.tsx
import React, { useState } from 'react';

interface DocumentUploadProps {
  caseId: string;
  onDocumentUploaded: (documentId: string) => void;
}

const DocumentUpload: React.FC<DocumentUploadProps> = ({ caseId, onDocumentUploaded }) => {
  const [selectedFile, setSelectedFile] = useState<File | null>(null);
  const [documentType, setDocumentType] = useState<string>('');
  const [description, setDescription] = useState<string>('');

  const handleFileChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    if (event.target.files && event.target.files.length > 0) {
      setSelectedFile(event.target.files[0]);
    }
  };

  const handleSubmit = async (event: React.FormEvent) => {
    event.preventDefault();

    if (!selectedFile) {
      alert('Please select a file.');
      return;
    }

    const formData = new FormData();
    formData.append('file', selectedFile);
    formData.append('caseId', caseId);
    formData.append('documentType', documentType);
    formData.append('description', description);

    try {
      const response = await fetch('/api/uploadDocument', {
        method: 'POST',
        body: formData,
      });

      if (response.ok) {
        const data = await response.json();
        onDocumentUploaded(data.documentId);
        alert('Document uploaded successfully!');
      } else {
        alert('Failed to upload document.');
      }
    } catch (error) {
      console.error('Error uploading document:', error);
      alert('Error uploading document.');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="document">Select Document:</label>
        <input type="file" id="document" onChange={handleFileChange} />
      </div>
      <div>
        <label htmlFor="documentType">Document Type:</label>
        <input
          type="text"
          id="documentType"
          value={documentType}
          onChange={(e) => setDocumentType(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="description">Description:</label>
        <textarea
          id="description"
          value={description}
          onChange={(e) => setDescription(e.target.value)}
        />
      </div>
      <button type="submit">Upload Document</button>
    </form>
  );
};

export default DocumentUpload;

This code demonstrates a basic document upload component with file selection, metadata input, and form submission. Replay can generate similar code for other UI elements and workflows within your legal case management system.

Here's an example of a secure API endpoint for retrieving case data, built using Supabase and potentially generated (or refined) after initial Replay reconstruction:

typescript
// pages/api/cases/[caseId].ts
import { createClient } from '@supabase/supabase-js';
import type { NextApiRequest, NextApiResponse } from 'next';

const supabaseUrl = process.env.SUPABASE_URL;
const supabaseKey = process.env.SUPABASE_ANON_KEY;

if (!supabaseUrl || !supabaseKey) {
  throw new Error('Missing SUPABASE_URL or SUPABASE_ANON_KEY environment variables.');
}

const supabase = createClient(supabaseUrl, supabaseKey);

export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {
  const { caseId } = req.query;

  if (req.method === 'GET') {
    try {
      const { data, error } = await supabase
        .from('cases')
        .select('*')
        .eq('id', caseId)
        .single();

      if (error) {
        console.error('Supabase error:', error);
        return res.status(500).json({ error: 'Failed to fetch case data' });
      }

      if (!data) {
        return res.status(404).json({ error: 'Case not found' });
      }

      res.status(200).json(data);
    } catch (error) {
      console.error('Server error:', error);
      res.status(500).json({ error: 'Internal server error' });
    }
  } else {
    res.status(405).json({ error: 'Method not allowed' });
  }
}

This endpoint retrieves case data from a Supabase database based on the

provided in the request. It includes error handling and ensures that only GET requests are allowed.
