AI Chat Implementation Findings

Executive Summary

The Biblical Guide codebase has a fully implemented AI chat system that is currently DISABLED. The chat functionality is present in the codebase but commented out in the main layout, preventing users from accessing it.

---

1. Current AI Chat Implementation Status

Status: DISABLED (But Fully Functional)

• Location of disable: /root/biblical-guide/app/[locale]/layout.tsx (Line 10, 133)
• The FloatingChat component is imported but commented out with note "AI Chat disabled"
• All API routes exist and are functional
• Database models are in place
• Frontend components are complete and ready

---

2. Frontend Components & Pages Structure

Main Chat Component

File: /root/biblical-guide/components/chat/floating-chat.tsx

• Type: Client-side React component ('use client')
• Features:
  • Floating action button (FAB) in bottom-right corner
  • Slide-in chat drawer with full conversation history
  • Supports fullscreen view with minimize/maximize
  • Left sidebar showing chat history with conversation management
  • Right side with message display and input
  • Multi-language support (Romanian, English, Spanish, Italian)
  • Real-time conversation persistence to database
  • Suggested questions for getting started
  • Conversation rename and delete functionality
  • Loading state with Bible-related messages

State Management:

• Local state for messages, conversations, UI modes
• Uses localStorage for auth token
• Integrates with global useAuth hook
• Conversation history loaded from /api/chat/conversations

Secondary Chat Component

File: /root/biblical-guide/components/chat/chat-interface.tsx

• Type: Simpler alternative chat interface (Client component)
• Status: Available but not currently used in main layout
• Uses Tailwind CSS instead of Material-UI
• Basic message display with markdown support

Integration Points

File: /root/biblical-guide/app/[locale]/page.tsx

• Chat is triggered via custom events: floating-chat:open
• Multiple buttons dispatch these events to open chat with:
  • Fullscreen mode
  • Initial message pre-populated
• Example: "Ask AI" buttons on home page and other pages

3. API Routes & Backend Implementation

Main Chat API

File: /root/biblical-guide/app/api/chat/route.ts

POST /api/chat - Main chat endpoint

• Authentication: Required (Bearer token)

• Request Body:

  {
    "message": "string",
    "conversationId": "string (optional)",
    "locale": "string (optional, default: 'ro')",
    "history": "array (optional, for anonymous users)"
  }
  

• Response:

  {
    "success": boolean,
    "response": "AI response text",
    "conversationId": "string (only if authenticated)"
  }
  

• Key Features:

  1. Authentication Check: Returns 401 if no valid Bearer token
  2. Conversation Management:
     • Creates new conversations for authenticated users
     • Loads existing conversation history (last 15 messages)
     • Maintains conversation metadata
  3. Subscription Limits:
     • Free tier: Limited conversations per month
     • Premium tier: Unlimited conversations
     • Uses /lib/subscription-utils to check limits
  4. Bible Vector Search:
     • Searches for relevant Bible verses using searchBibleHybrid()
     • Supports language-specific filtering
     • Includes verse references in context (5 verses max)
  5. Azure OpenAI Integration:
     • Calls Azure OpenAI API with formatted messages
     • Supports multiple languages with specific system prompts
     • Temperature: 0.7, Max tokens: 2000
     • Handles content filtering responses
  6. Fallback System:
     • Language-specific fallback responses if Azure OpenAI fails
     • Gracefully degrades without blocking chat

Conversation Management API

File: /root/biblical-guide/app/api/chat/conversations/route.ts

GET /api/chat/conversations - List user conversations

• Query Parameters:
  • language (ro|en, optional)
  • limit (1-50, default: 20)
  • offset (default: 0)
• Returns: Paginated list of conversations with last message preview

POST /api/chat/conversations - Create new conversation

• Request: { title, language }
• Returns: Created conversation object

Individual Conversation API

File: /root/biblical-guide/app/api/chat/conversations/[id]/route.ts

• PUT: Rename conversation
• DELETE: Soft delete conversation (sets isActive to false)

Admin API Routes

Files:

• /root/biblical-guide/app/api/admin/chat/conversations/route.ts
• /root/biblical-guide/app/api/admin/chat/conversations/[id]/route.ts

AZURE_OPENAI_DEPLOYMENT=gpt-4o
AZURE_OPENAI_API_VERSION=2025-01-01-preview

AI Response Generation

Function: generateBiblicalResponse() in /root/biblical-guide/app/api/chat/route.ts

Process:

1. Uses searchBibleHybrid() to find relevant Bible verses with language filtering
2. Extracts version information from database source tables
3. Creates language-specific system prompts (Romanian, English, Spanish)
4. Implements smart context building from conversation history:
   • Always includes last 6 messages for immediate context
   • Finds relevant older messages based on keyword/biblical reference matching
   • Applies token-based truncation (~1500 tokens max for context)
   • Can summarize older messages if needed
5. Calls Azure OpenAI REST API with:
   • System prompt with Bible context and instructions
   • Current user message
   • Conversation history (smart context)
6. Returns formatted response with Bible version citations

System Prompts:

• Language-specific (Romanian, English, Spanish supported)
• Instructs AI to cite Bible versions as "[Version] Reference"
• Emphasizes accuracy and empathy
• Mentions biblical passages found in context
