Benefits of the Automatic Testing Agent

One of the most challenging parts of AI coding is fixing minor bugs. Emergent features a 'Testing Agent' that automatically tests your app in the background, so you don't have to manually take screenshots of errors and re-upload them to the AI for troubleshooting.

AI Model Selection Tips

If your application is intended for high usage, opt for a 'Mini' model (such as GPT-4o Mini). It is faster and more cost-effective than full-scale models, even if the reasoning quality is slightly lower.

Universal API Key

Emergent simplifies the process by providing a 'Universal Key'. This means you don't need to sign up for separate OpenAI or Anthropic accounts just to get an API Key to run AI features within your app.

Step by Step

Initial Steps & Project Configuration

  1. Access the Emergent website and enter a brief prompt in the main text area.
  2. Use the chat interface to discuss with the AI to validate your idea or add more specific project details.
  3. Select an AI agent from the dropdown menu; choose 'Stable and thorough agent' (the default) for more detailed results.
  4. (Optional) Click 'Add image' to upload a screenshot of another website if you want Emergent to replicate that UI style.
  5. (Optional) Connect your GitHub account via the GitHub Connection option for version control purposes.
  6. Click on 'Advanced Settings' if you wish to enable the 'Ultra thinking model' for more complex application logic.
  7. Click the 'Send' button to begin the application generation process.

AI Integration & Database Configuration

  1. Answer follow-up questions from the Emergent agent regarding the AI model you want to use (specifically for AI-driven apps).
  2. Select an AI model from the list (e.g., GPT-4o Mini for speed and low cost, or a flagship model for higher quality).
  3. Select the 'Universal Key' provided by Emergent in the API Key section to avoid a complicated manual API setup process.
  4. Specify your preferred design style (e.g., 'Modern UI') when prompted by the agent.
  5. Let the system run the 'Testing Agent' automatically to detect and fix bugs without manual intervention.
  6. Review the summary of core functions and features completed by the agent before moving on to the deployment phase.
