🎨 Discovering Lexica.art: A Guide to Generating Stunning AI Art

This video tutorial guides viewers through utilizing Lexica.art to find inspiration, understand prompt use for enhancing images, and generate their own high-quality images directly from the platform. Unlike Meet Journey, where only 25 free images are available monthly, Lexica allows the creation of up to 100 free images. The video begins by showing how to access Lexica.art, presenting a variety of spectacular user-generated images and detailing how to view the prompts and characteristics used for each. It then explains how to use the site's search functionality to filter images by theme, such as mountains, to display related images with different prompts, characteristics, and styles. The process of generating images on Lexica is demonstrated, highlighting the ability to create up to 100 free images per month, the use of a text box for image description, and the inclusion of 'negative prompts' to exclude specific concepts. The tutorial showcases the unique aspects of Lexica, such as its training on proprietary models not commonly used on other platforms, providing an easy-to-use web interface for generating aesthetically pleasing images with almost the same quality level as Meet Journey, without the need to sift through hundreds of user-generated images. Finally, the video demonstrates the 'out paint' feature, which creates a coherent environment around the generated images, offering an easy and comfortable platform not just for creating AI images but also for learning to correctly describe them with specific prompts and finding inspiration.




Lexica.art is described in the video as a website where users can generate high-quality images using artificial intelligence, similar to the capabilities of another platform mentioned, Meet Journey. It stands out by allowing users to generate up to 100 free images per month. Lexica.art serves as a practical tool for finding inspiration, understanding how prompts can improve image quality, and creating custom images directly on the platform.


Prompts are textual inputs that describe the desired output image in AI image generation tools. In the video, prompts are crucial for guiding the AI to produce specific types of images, such as 'geometric mountains in 3D with moons, stars, etc.' Understanding how to effectively use prompts is essential for utilizing lexica.art and other AI-based image generation platforms, as it directly affects the creativity and quality of the generated images.

💡Free images

The video highlights that unlike Meet Journey, lexica.art offers the ability to generate up to 100 free images per month.
