Example

  selectedModel: 'gpt-4-turbo',
  theme: 'dark',
  accent: 'violet',
  systemPrompt: 'You are a helpful AI assistant.',
  tone: 'professionnel',
  notificationsEnabled: true,
  ragEnabled: false,
  hasOnboarded: true
};

​
Usage

Settings are typically stored in local storage and loaded on app initialization: 
// Load settings
const loadSettings = (): Settings => {
  const stored = localStorage.getItem('polychat-settings');
  if (stored) {
    return JSON.parse(stored);
  }
  
  // Default settings
  return {
    apiKey: '',
    selectedModel: 'gpt-4',
    theme: 'dark',
    accent: 'violet',
    systemPrompt: 'You are a helpful AI assistant.',
    tone: 'neutre',
    notificationsEnabled: true,
    ragEnabled: false,
    hasOnboarded: false
  };
};

// Save settings
const saveSettings = (settings: Settings) => {
  localStorage.setItem('polychat-settings', JSON.stringify(settings));
};

​
System Prompt

The systemPrompt field is particularly important as it defines the AI’s behavior: 
// Example system prompts for different use cases
const codingAssistant: string = 
  'You are an expert programming assistant. Provide clear, well-documented code with explanations.';

const creativeWriter: string = 
  'You are a creative writing assistant. Help users craft engaging stories and content.';

const dataAnalyst: string = 
  'You are a data analysis expert. Help users understand and interpret data with clear insights.';
