Midjourney is an AI image generation service that creates artwork from text prompts. Users describe what they want to see, and Midjourney produces four image variations to choose from. The platform is known for its distinctive artistic style, producing images with rich textures, dramatic lighting, and a painterly quality that sets it apart from competitors. Beyond basic generation, Midjourney offers style reference, character reference, regional variation, and remix modes for refining results. Originally accessible only through Discord, it now has a full web interface and has expanded into video generation.
