What is Caistom?

caistom is a free browser-based custom apparel and print design tool with built-in AI image generation. Users describe an image or upload their own art, place it on products like t-shirts, hoodies, posters, mugs, and tote bags, and order print-on-demand items with no minimum order. Production runs through Gelato's print network in 30+ countries, so orders are printed close to the customer and shipped worldwide.

How to use Caistom?

1. Describe an image in the AI prompt bar to generate print-ready art with a transparent background, or upload your own images and add text in 18 fonts. 2. Design on the layered canvas: move, scale, rotate, and reorder elements while previewing them on product mockups. 3. Pick a size and color, enter your address, and order — single items are welcome with no minimum. 4. Your design gets a quick human review, then it is printed by Gelato at the facility nearest you and shipped.
