Nano Banana is LIVE in Kittl Flows Watch Me Build Designs FAST

About this video

The creator shows how to use the Nano Banana model inside Kittl Flows, selecting the model on a Smart Board and prompting it in conversational language, which he compares to talking to Gemini or ChatGPT. Starting from an existing template design, he generates a series of mockups: the design on a coffee mug on a table, on a t-shirt on a wood surface, and on t-shirts worn by a woman and a man, commenting on how realistic the person and shadowing look. He then changes shirt colors, including to purple, and changes a background to a living room, showing how individual elements can be revised without starting over. In a second workflow he starts a new project using a Merch by Amazon canvas, prompts a funny cow in a Santa hat and scarf for a Christmas design, and notes that including the word t-shirt in the prompt tends to make the generator render the design on a shirt. He removes the background, then uses more Smart Boards to change the scarf color, switch the text to all white and then all black so the design works on different shirt colors, and swap the main character from a cow to a pig, a monkey and Santa Claus. He also uses a chat box to generate playful slogan ideas, and frames the whole process as a fast way to scale one idea into many variations for Merch by Amazon, Etsy or a seller’s own site.
