πŸ’‘Lexica AI

Lexica AI is the central focus of the video, referring to an artificial intelligence platform that generates images based on user input. It is described as a tool that allows users to create their own images by typing in descriptions and adjusting settings. The video provides a tutorial on how to use the Lexica AI website, including its interface and features.


In the context of the video, 'Generate' refers to the action of creating or producing an image using Lexica AI. Users input their desired image characteristics, such as objects or scenes, and the AI generates a corresponding image. This process is a core functionality of the Lexica platform and is emphasized throughout the tutorial.


Dimensions in the video refer to the aspect ratio or shape of the generated image. Users have the option to adjust the dimensions to create a landscape, portrait, or square image. This feature allows for customization of the image's layout to fit the user's preferences or requirements.

πŸ’‘Advanced Settings

Advanced Settings in the video pertain to additional options that users can modify to influence the image generation process. These settings include model type and guidance scale, which affect the style and accuracy of the generated images. Advanced settings provide users with more control over the output, allowing for fine-tuning of the AI's creativity and adherence to the input.

πŸ’‘Negative Prompts

Negative prompts are a feature in Lexica AI that allows users to specify elements they do not want to appear in the generated image. By typing in what should be excluded, the AI can better understand the user's preferences and create an image that meets those criteria. This helps in refining the output to be more aligned with the user's vision.

πŸ’‘Guidance Scale

The Guidance Scale is a parameter within Lexica AI that determines the level of control the user has over the image generation process. A lower guidance scale allows for more creativity from the AI, potentially resulting in more unique but less predictable images. Conversely, a higher guidance scale increases the precision and adherence to the user's input, ensuring a more accurate representation of the desired image.

πŸ’‘Image to Image

Image to Image is a feature of Lexica AI that enables users to upload an existing image and generate a new image based on that template. This allows for the creation of customized images that incorporate elements from the uploaded image, offering users a way to integrate their own visual elements into the AI-generated content.

πŸ’‘History and Likes

History and Likes are features of the Lexica AI platform that allow users to review and save their previously generated images. The history logs all the images created by the user, while the likes section enables users to bookmark or favorite specific images for easy access and future reference. These features enhance user experience by providing a way to organize and revisit past creations.

πŸ’‘Membership Plans

Membership Plans refer to the subscription options available to users of the Lexica AI platform. These plans vary in price and offer different levels of access and features, allowing users to choose a plan that suits their needs and usage. The video mentions various plan names and prices, indicating that users have options to select from based on their budget and requirements.
