          Trouble authenticating?
          No API key is currently saved. Add one under Settings → API key if your provider requires it. Local endpoints
            and public routes such as OpenRouter’s model list may work without a key.
          Double-check your endpoint or import your saved settings file.
        
    
        
    
          
          
        
    
      
    
      
    
        
        
      
    
      
    
      
    
        
    
          
          
    
        
    
        
        
      
    
    
    
  
    

  
    

  
    
  
    
    
    
      
    
        
    Private & Local — About this demo
    
        
      
    
      
    
        
    The app runs in your browser. Your chats are stored locally. On-device models generate locally; choosing an API provider sends conversation context to that provider.
    

        
    How to run it anywhere
    
        
      
          
    • Desktop: Install this app from your browser, or bookmark it.
      • 
          
    • iPhone (Safari): Share → Add to Home Screen, or Share → Save to Files, then open it.
      • 
        
    

        
    What’s stored locally
    
        
      
          
    • localStorage: chat threads and messages.
      • 
          
    • sessionStorage: settings (endpoint, token, model, theme) for the current session.
      • 
        
    
        
    Model downloads require a connection. After installation, on-device chat can work offline. API mode uses your selected provider.
