I Tested Kittl’s Flux AI for Print On Demand – Is It a Game Changer?

About this video

He tests Kittl’s Flux AI image generator for print-on-demand sellers. In Kittl he opens Tools > Image Generator, goes to Advanced, and chooses Flux 1.1 Pro over DALL-E 3, setting a 1:1 aspect ratio and using Kittl’s provided image styles, with prompts built in ChatGPT (including a dedicated GPT) rather than written from scratch — stressing you can regenerate until a prompt fits. First test: a futuristic neon sneaker prompt produces several clean, detailed images with strong lighting, ground/background effects and silhouettes, which he frames less as a t-shirt graphic and more as ad/product imagery for Facebook, Instagram or TikTok, or for flyers and books. Second test: using a Flux portrait-prompt GPT with inputs such as green eyes, long hair, medium skin tone, expression and an indoor/natural background, he generates photorealistic portraits of a woman and then a man, praising skin, eyes, hair and sunlight detail across repeated generations, and suggests plugging such portraits into lip-sync/AI-model tools for faceless content and monetised AI-model videos. Third test: he asks ChatGPT for a short storybook outline and illustration prompts about a rabbit named Rosie meeting a turtle named Toby, then generates each scene in Flux. He likes the water, ground, flowers and sunset detail, but shows the limits too: styles drift between realistic and cartoonish, the rabbit’s colouring changes between scenes, and one image has an extra foot — concluding a real book would need tighter prompts and consistent characters throughout.

Key takeaways

• In Kittl’s Advanced image generator he selects Flux 1.1 Pro over DALL-E 3 and pairs it with prompts generated and regenerated in ChatGPT
• His neon sneaker test produced clean, detailed, ad-style product imagery he suggests using for social ads, flyers and books, not just t-shirts
• Photorealistic portrait tests impressed him on eyes, skin, hair and lighting, and he suggests using them for faceless content / AI-model videos via lip-sync tools
• For the Rosie-the-rabbit and Toby-the-turtle storybook, ChatGPT supplied the outline and per-scene illustration prompts which he then generated one by one in Flux
• The storybook test exposed Flux’s consistency limits: style drift, a character’s colouring changing between scenes, and an extra foot, so prompts and character consistency need tightening
