How it's made

Challenges we ran into ## 🎯 Challenges We Ran Into ### 🤖 AI Content Verification System - **Challenge**: Needed to verify legal document authenticity and cross-reference evidence - **Problem**: AI would sometimes lose context between different pieces of evidence - **Solution**: ```python # Implemented a content verification system using file-based context os.makedirs('content-verification', exist_ok=True) file_path = os.path.join('content-verification', 'case.txt') with open(file_path, 'w', encoding='utf-8') as f: f.write(case_data.description) # For each piece of evidence for file in evidence_data.evidences: reference_file_path = os.path.join('content-verification/references', f"{file.original_name.split('.')[0]}.txt") with open(reference_file_path, 'w', encoding='utf-8') as f: f.write(file.description) ``` ### 📝 Real-time PDF Generation - **Challenge**: Needed to generate court documents in real-time as conversations progressed - **Problem**: PDF merging would sometimes corrupt files during concurrent updates - **Solution**: ```python def append_to_case_pdf(case_id: str, conversation: LawyerContext): try: # Create temporary PDF for new content temp_pdf = f'case_reports/temp_{case_id}.pdf' doc = SimpleDocTemplate(temp_pdf, pagesize=letter) # Merge with existing PDF using PyPDF2 merger = PdfMerger() if os.path.exists(pdf_filename): merger.append(PdfReader(open(pdf_filename, 'rb'))) merger.append(PdfReader(open(temp_pdf, 'rb'))) ``` ### 🔄 WebSocket Implementation Hurdles - **Initial Challenge**: Implementing real-time bidirectional communication between human lawyers and AI agents proved complex - **Problem**: WebSocket connections would drop during long AI processing times - **Outcome**: Stable connections maintained even during extended AI processing
