To create AI-generated images from scratch, you can use AI image generators that utilize trained artificial neural networks to generate images based on textual input provided in natural language. These generators have the capacity to create original, realistic visuals based on the input text. Some popular AI image generators include Photoroom, MLearning.ai, UniteAI, OpenAI API, DALLE, Imagen, DeepAI, MinImagen, and Adobe Firefly. These tools allow you to start a design project from scratch or with a template, and then generate an image from a text description. The more detail you can provide in the text description, the better the AI image generator will be able to create an image that reflects the semantic information contained within the prompt. Keep in mind that the quality of the generated image may not be photorealistic, but these tools can still be useful for generating AI art or for general creative experimentation.
