Help me get a free Google Gemini API key for Phantomline.

1. Open https://aistudio.google.com/apikey in my browser.
2. Sign in with my Google account.
3. Click 'Create API Key' and select or create a Google Cloud project.
4. Copy the generated key.
5. In Phantomline, go to Settings → AI engine → Cloud, choose 'Gemini' as the provider, and paste the key.
6. The key is saved to my browser's localStorage — it never touches Phantomline's server.
7. Test by generating a script. It should complete in a few seconds using Gemini Flash.

      
      

        What Claude will do for you:
        
    
          
  1. Detect your OS
    2. 
          
  2. Check whether prerequisites are installed (Python, Git, etc.)
    3. 
          
  3. Install anything missing
    4. 
          
  4. Install Google Gemini API key and download model weights
    5. 
          
  5. Verify the install worked
    6. 
          
  6. Tell you when it's done
    7. 
        

        

          You'll see Claude ask for permission before running each install command. You can approve all or step through.
        

      

    

  


  
  

    
    

      
1Open Google AI Studio

      
Go to aistudio.google.com/apikey and sign in with any Google account. No credit card is required.

      
      
      
    

    
    

      
2Create an API key

      
Click Create API Key. Select an existing Google Cloud project or let it create one for you. The key appears instantly — copy it.

      
      
      
    

    
    

      
3Paste the key into Phantomline

      
Open the studio, go to Settings → AI engine → Cloud. Select Gemini as the provider and paste your key. It's saved to your browser's localStorage and never sent to Phantomline's server.

      
      
      
    

    
    

      
4Generate a test script

      
Pick any topic and hit Generate. Your browser calls the Gemini API directly. Scripts come back in a few seconds. The free tier supports Gemini 2.0 Flash and Gemini 2.5 Pro with generous rate limits.

      
      
      
    

    
  


  

    
Verify it worked

    
Generate a script in the studio. If it completes successfully, your Gemini API key is working.

    
    

      Then:
      Reload /app — the readiness checklist will flip Google Gemini API key to READY.
