   • Copy the contents of supabase_schema.sql
   • Run the SQL to create all tables and types

3. Run the migration for the ai_draft status:

   • Copy the contents of supabase_migrations.sql
   • Run the SQL in the SQL Editor

4. (Optional) Add sample data:

   • Copy the contents of supabase_seed.sql
   • Run the SQL to add sample projects and chapters

3. Environment Configuration

1. Copy the example environment file:

   cp .env.local.example .env.local

2. Update .env.local with your credentials:

   NEXT_PUBLIC_SUPABASE_URL=your_supabase_project_url
   NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key
   SUPABASE_SERVICE_ROLE_KEY=your_supabase_service_role_key
   OPENAI_API_KEY=your_openai_api_key
   OPENAI_MODEL=gpt-4o
   NEXT_PUBLIC_APP_URL=http://localhost:3000
   

4. Installation

Install dependencies:

npm install

5. Run the Application

Usage

Creating a Project

1. Navigate to the home page
2. Click "New Project" (functionality to be implemented)
3. Fill in project details including title, genre, tropes, POV, and heat level

Generating AI Drafts

1. Click on a project to view its details
2. Find the chapter you want to generate
3. Click the "Generate AI Draft" button
4. The AI will generate a draft based on:
   • Project metadata (genre, tropes, POV, heat level)
   • Chapter number and title
   • Previous chapter context (if available)
   • Target word count

Chapter Status Flow

• not_started → Initial state
• in_progress → Being worked on
• ai_draft → AI draft has been generated
• draft_complete → Human-edited draft ready
• under_review → Being reviewed
• approved → Approved for publication
• published → Published

API Endpoints

POST /api/ai-draft

Generates an AI draft for a chapter.

Request Body:

{
  "chapterId": "chapter-uuid",
  "projectId": "project-uuid"
}

Response:

{
  "success": true,
  "draft": {
    "id": "draft-uuid",
    "content": "Generated chapter content...",
    "model_used": "gpt-4o",
    "pass_number": 1,
    "total_cost": 0.0234
  },

}

Cost Tracking

The application automatically tracks OpenAI API costs:

• GPT-4o: $5/1M input tokens, $15/1M output tokens
• GPT-4 Turbo: $10/1M input tokens, $30/1M output tokens
• GPT-3.5 Turbo: $0.50/1M input tokens, $1.50/1M output tokens

Costs are stored per draft and aggregated at the project level.

Database Schema

The application uses the following main tables:

• users: System users (admins, AI agents, beta readers)
• projects: Romance book projects
• chapters: Individual chapters within projects
• ai_drafts: AI-generated chapter drafts
• final_chapters: Approved final versions
• feedback: Beta reader feedback

Future Enhancements

• User authentication and authorization
• Project creation and editing UI
• Chapter content viewer and editor
• Beta reader feedback system
• Export to various formats (EPUB, PDF)
• Advanced prompt customization
• Multiple AI model support
• Revision and editing workflows
• Publishing integration
