Use AI Agent to generate applications

Replit AI Agent can automatically generate and deploy complete applications based on natural language descriptions.

Scenario

(Click "Create with AI" in Replit)

"Creating a personal blog website requires:
- The homepage displays the latest 5 articles
-Supports article content in Markdown format
- Has label classification function
- Simple responsive design
- Using the Python Flask backend"
Output / what to expect

Replit AI Agent will:

  1. Automatically generate Flask backend code
  2. Create HTML/CSS front-end template
  3. Configure routing and data storage
  4. Automatically install dependencies
  5. Run the app and provide a preview link The whole process takes about 2-3 minutes and requires no manual operation.

The more specific the description, the more likely the resulting app will be as expected. You can continue to modify it in natural language after generation.

Scenario

Quickly create API services

Prompt example
"Create a REST API with the function:
- POST /shorten receives long URL and returns short link
- GET /{code} redirects to the original URL based on the shortcode
- Using Python FastAPI
- Data is stored in memory (simple version)
- Contains API documentation (Swagger)"
Output / what to expect
Replit AI generates a complete short link service, Contains FastAPI code, automatic documentation, After deployment, obtain the API address accessible from the public network. Can be used directly for testing and demonstration.
Tips
