Caistom

Caistom is a free online editor with built-in AI image generation for designing T-shirts, hoodies, posters, mugs and totes. Orders print on demand with no minimum and ship worldwide through the Gelato network.

Caistom is an online design studio for custom apparel and printed goods that builds AI image generation directly into the editor. A user types a prompt, receives artwork with a transparent background on the canvas, and places it on a product mockup. Orders are printed on demand and shipped, so a single shirt is as welcome as a batch. The catalog covers T-shirts, hoodies, sweatshirts, tank tops, posters, large wall art, trucker hats, dad hats, mugs and tote bags. Each product page lists its fabric or paper weight, size range and starting price before shipping, and shipping coverage reaches more than 230 countries for most items. Front and back prints are designed as separate designs, then matched to the corresponding product option when ordering. In practice the workflow has four stages. Artwork comes from a text prompt or from uploaded images, with text added in 18 fonts. The editor is a layered canvas where elements can be moved, scaled, rotated and reordered while mockups update. At checkout the buyer picks a size and color and enters an address. Every design goes through a short human review before printing, and production is handled by the Gelato print network across 30+ countries, which keeps fulfillment close to the buyer. The stated timeline is production within about 72 hours and delivery within roughly a week. The tool suits hobbyists, small shops testing slogans, gift makers and anyone who wants one-off merchandise without learning design software. Designing needs no account, and the editor is free, so spending only happens on a physical order. Guests get a limited number of free AI generations per day, with a larger allowance after signing in. Compared with general AI image generators, Caistom trades flexibility for a complete path from idea to delivered product. Compared with print-on-demand storefront platforms, it is aimed at personal orders rather than running a store. Mobile apps exist for iOS and Android alongside the web editor.
