The video begins with the host expressing gratitude for the audience joining another walkthrough/tutorial on an AI tool. The focus is on Lexicon, a stable diffusion search engine likened to Google for AI art. The host explains that Lexicon is an engine that generates images based on prompts provided by users. The host encourages viewers to subscribe, like, comment, and share the video if they are interested in AI technology. The tutorial starts with exploring the search function of Lexicon, followed by the generate function, and the host expresses excitement about the capabilities of Lexicon. The homepage of Lexicon is showcased, displaying a grid of AI-generated creations, and the host selects an image to delve into its features, such as the like option, prompt deconstruction, style exploration, and the unique seed number for generating similar images. The guidance scale and dimensions are also discussed, along with the ability to explore different types of artwork generated from a single prompt.


🔍 Searching and Reverse Image Search on Lexicon

The host continues the tutorial by demonstrating the search function on Lexicon, starting with a search for 'sourdough' and then moving on to a more specific search for 'Pea Blinders', a favorite TV show. The host highlights the ability to reverse search by uploading an image, using an example of Cillian Murphy from Peaky Blinders. The search results showcase AI-generated images that match the prompts. The host then transitions to the generate function, explaining the interface and the process of creating AI art. The guidance scale is further explained, with the host choosing a lower setting for more diversity and inspiration. The host shares tips for creating great AI art, including a formula that involves starting with the medium, subject, and additional details. The host creates an oil painting of a Boston Terrier in a psychedelic garden, inspired by artist Fernando Potato, and shares the result. The tutorial concludes with the host encouraging viewers to create and share their own AI-generated art and to connect with them on social media.



💡AI Tool

The term 'AI Tool' refers to artificial intelligence software or applications designed to perform specific tasks, often mimicking human cognitive functions. In the context of the video, the AI Tool being discussed is Lexicon, an AI-powered search engine for generating art based on user prompts. It exemplifies how AI can be utilized in creative processes, allowing users to generate unique pieces of digital art by simply inputting descriptions or prompts.

💡Stable Diffusion Search Engine

Stable Diffusion Search Engine is a term used to describe the AI art generation platform, Lexicon, which operates on a stable diffusion model. This model is a type of deep learning algorithm that can generate high-quality images from textual descriptions. The engine is likened to a search engine, but instead of searching for existing content, it creates new images based on the input provided by the user.


In the context of AI art generation, a 'prompt' is a textual input or description given by a user to guide the AI in creating an image. The prompt serves as a blueprint for the AI to understand the desired theme, style, and elements that should be present in the generated artwork. It is a crucial component of the AI art creation process as it directly influences the output.

💡Generate Function

The 'Generate Function' refers to the feature within AI art platforms like Lexicon that allows users to create new images based on their prompts. This function is the core of the AI art creation process, where the AI takes the user's textual input and translates it into a visual representation. The generate function is what enables the transformation of ideas and descriptions into tangible pieces of digital art.


In AI art generation, a 'seed' is a unique numerical value that is used by the AI algorithm to generate a specific image. The seed is essential because it ensures that the AI can recreate a similar base image if needed. By altering the seed value, users can generate variations of the original image, allowing for a degree of control over the AI's creative output.

💡Guidance Scale

The 'Guidance Scale' is a parameter within AI art generation platforms that adjusts the level of adherence to the user's prompt. A higher guidance scale value means the generated image will closely follow the prompt, while a lower value allows for more creative freedom and diversity in the output. It is a tool that balances the precision of the AI's interpretation with the user's desire for unique and unexpected results.


The term 'Artwork' refers to any creation that is visually or aesthetically engaging and is often created to express ideas, emotions, or concepts. In the context of the video, artwork is specifically referring to the digital images generated by the AI tool Lexicon, based on the user's prompts and creative direction.

💡Reverse Search

Reverse search, also known as image search, is a function that allows users to upload an image and find similar images or content based on the visual characteristics of the uploaded image. In the context of AI art generation, reverse search enables users to upload an existing image and request the AI to generate new images that are similar in style or content to the uploaded image.


In the context of digital art and image generation, 'Dimensions' refers to the size and shape of the image, typically measured in pixels or other units of length. It determines the aspect ratio and the overall scale of the artwork, which can influence the composition and the way the content is displayed.


In art, 'Medium' refers to the materials and techniques used to create an artwork. In the context of AI-generated art, specifying a medium like 'oil painting' or 'watercolor' guides the AI to produce images that mimic the visual characteristics and style associated with that medium.

💡Fernando Potato

Fernando Potato is an artist mentioned in the video script, known for his unique style that the user admires. The reference to this artist is used as an example of how users can specify a particular artistic style when generating AI art, indicating a preference for the AI to draw inspiration from specific artists or styles.
