Automagine is a tool that utilizes AI to generate beautiful art and images from text input. By inputting a descriptive text and clicking a button, the generated image can be added to a document or presentation and saved to a folder named 'diffusion-images'. It supports an art mode, enabling the creation of modern art works similar to Mid journey or Dall-e. It also supports prompt enhancement, allowing users to leverage GPT-3 for more detailed prompts. The application is free to use, with some features requiring payment.
