AI-powered insurance claim processing system with Camel-AI powered agent, automated OCR extraction, intelligent validation, and natural language queries.

Comment 1

Inspiration

Have you ever submitted an insurance/medical claim and waited days for approval? We've been there. Behind the scenes, claim processors spend 5-10 hours daily manually entering data from documents—tedious, error-prone, and expensive work that frustrates everyone involved.

We thought: What if AI could do the heavy lifting? That's where CAMEL-AI's multi-agent system comes in. We wanted to build something that actually solves a real problem—automating claim processing from document upload to approval, while keeping security tight with proper role-based access control.

What it does

ClaimSphere AI turns a 10-minute manual process into 30 seconds of automated intelligence using a sophisticated CAMEL-AI multi-agent system:

For users submitting claims:

  • Drag and drop claim documents (PDF, JPG, PNG)
  • AI-powered extraction - CAMEL-AI agents automatically extract key fields—names, dates, amounts, policy numbers using OLLAMA (phi3:mini) and ERNIE 5.0 Thinking
  • Review and correct extracted information if needed
  • Track claim status in real-time
  • AI Assistant - Ask questions in plain English: "What's my total approved amount?" Get concise, relevant answers with reasoning traces

For agents reviewing claims:

  • Prioritized review queue showing what needs attention
  • AI confidence scores for each extracted field
  • Gen AI Review - Role-playing AI agents (Reviewer + Approver) simulate human-like claim review with detailed assessments
  • One-click approve, deny, or request more info after AI review
  • Automatic duplicate claim detection with >85% accuracy
  • Comprehensive analytics dashboard

The smart stuff behind the scenes:

CAMEL-AI Multi-Agent System:

  • 8 Specialized AI Agents working together:
    • OCR Agent (PaddleOCR) - Document text extraction
    • Extraction Agent - Intelligent field extraction with reasoning
    • Validation Agent - Smart validation with explainable decisions
    • Fraud Detection Agent - Risk assessment with >85% accuracy
    • Duplicate Detection Agent - Prevents duplicate submissions
    • Query Agent - Natural language queries with concise answers
    • Review Agent - Role-playing Senior Claims Reviewer
    • Approval Agent - Role-playing Claims Approver

Role-Playing AI Review:

  • Two AI agents (Reviewer + Approver) simulate realistic claim review discussions
  • Multi-turn conversations for complex cases
  • Detailed assessments with key findings, concerns, and recommendations
  • Policy references and conditions for decisions
  • Confidence scores and reasoning traces

Auto-approval: Automatically approves 40-60% of low-risk claims

Fraud detection: Catches duplicates and suspicious patterns (>85% accuracy)

Natural language queries: Ask questions, get concise answers—no SQL needed. Powered by OLLAMA (phi3:mini) for fast, local processing

Complete audit trail: Everything logged for compliance

The impact:

  • 95% faster processing (10 min → 30 sec)
  • 60-70% cost reduction through automation
  • >95% accuracy in field extraction
  • >85% accuracy in duplicate detection
  • Explainable AI - Every decision comes with reasoning traces

How we built it

Tech Stack:

Backend:

  • FastAPI + PostgreSQL (Railway)
  • CAMEL-AI Framework - Multi-agent orchestration system
  • OLLAMA - Local open-source LLM (phi3:mini) for fast, free AI processing
  • Baidu ERNIE 5.0 Thinking API for advanced AI processing (fallback)
  • PaddleOCR 3.x for document processing
  • JWT auth with role-based access control

Frontend:

  • Next.js 14 + TypeScript (Vercel)
  • React Context API for state management
  • Polished UI with dark/light mode support
  • Real-time claim status tracking
  • AI Assistant chat interface
  • Role-playing review interface

DevOps:

  • Railway (Backend + OLLAMA service)
  • Vercel (Frontend)
  • Docker containerization
  • Git-based CI/CD

Development Process:

We started with solid architecture planning - database design, API structure, and RBAC model. Then built the FastAPI backend with CAMEL-AI multi-agent system integration:

  1. Agent Architecture - Designed 8 specialized agents, each with a specific role
  2. OLLAMA Integration - Set up local LLM (phi3:mini) for fast, free AI processing
  3. Role-Playing System - Implemented CAMEL-AI role-playing framework for realistic claim review
  4. Query Agent - Built natural language query system with reasoning traces
  5. Frontend - Built Next.js frontend with role-based dashboards, AI Assistant, and role-playing review interface
  6. Testing & Optimization - Optimized prompts, reduced token usage, improved response times
  7. Deployment - Deployed to Railway (Backend + OLLAMA) and Vercel (Frontend)

Challenges we ran into

1. Memory Issue: PaddleOCR Segmentation Faults

Problem: PaddleOCR needs ~800MB RAM and can crash with segmentation faults on certain files, crashing the entire backend.

Solution:

  • Added comprehensive file validation before processing
  • Implemented timeout protection (30 seconds)
  • Added graceful error handling for segfaults
  • Made OCR optional via DISABLE_OCR environment variable
  • Added file size limits (max 50MB) and format validation

Lesson: Always validate inputs and handle C++ library crashes gracefully.

2. OLLAMA Timeout Issues

Problem: OLLAMA queries were timing out, even with increased timeouts.

Solution:

  • Optimized prompts to be ultra-concise (single line, minimal context)
  • Reduced max_tokens to 150-256 for faster responses
  • Limited context to 8 recent claims for queries
  • Set appropriate timeouts (90s for agents, 95s step timeout)
  • Used phi3:mini model for fastest performance
  • Added fallback to local answer generator if OLLAMA fails

Lesson: Model optimization is crucial - shorter prompts and lower token limits dramatically improve response times.

3. OCR Model Download Timeouts

Problem: PaddleOCR tried downloading huge models during deployment, causing timeouts.

Solution: Added explicit checks to prevent OCR initialization when disabled—stopping it before any memory allocation.

Lesson: Lazy initialization and feature flags are essential for cloud deployments.

4. RBAC for Natural Language Queries

Problem: How do you let users ask questions while ensuring they only see their own claims?

Solution: Built context-aware filtering that happens before OLLAMA processes the query, automatically scoping results based on user role. The Query Agent receives pre-filtered claims context.

Lesson: Security must be enforced at the data layer, not just the API layer.

5. Railway OLLAMA Connection Issues

Problem: Backend couldn't connect to OLLAMA service on Railway, even with environment variables set.

Solution:

  • Used load_dotenv(override=False) to prevent overriding Railway's environment variables
  • Added /env-check endpoint for debugging
  • Enhanced startup logging to show environment variables
  • Configured both private (ollama.railway.internal) and public URLs
  • Added comprehensive error handling and fallback mechanisms

Lesson: Environment variable loading can be tricky in cloud deployments - always verify with diagnostic endpoints.

6. AI Response Formatting

Problem: AI responses were showing raw JSON and long text, making them hard to read.

Solution:

  • Implemented text truncation (100-150 chars) for long responses
  • Added summary cards for key metrics (confidence, assessment)
  • Created collapsible sections for detailed reasoning
  • Improved visual hierarchy with better spacing and colors
  • Added item counts to section headers

Lesson: UX matters - even the best AI is useless if users can't understand the output.
