Introducing SPLICE LAB · ShirtPrompt

Say hello to SPLICE LAB — The creepy-cute genetics wing: mutant cuties, gene-spliced hybrids, and DNA built from candy, bones, and snakes — FreakPress’s science-fair sibling.. It's now live in the ShirtPrompt store and ready to turn into shirt designs that sell.

Why we built SPLICE LAB

Staring at a blank canvas is the hardest part of print-on-demand. SPLICE LAB fixes that: instead of guessing at wording and art direction, you get instant, on-trend prompts tuned for this exact niche (The creepy-cute genetics wing: mutant cuties, gene-spliced hybrids, and DNA built from candy, bones, and snakes — FreakPress’s science-fair sibling.). Spin up fresh ideas in seconds, then send them to your favorite AI image tool to render the artwork.

Who it's for

SPLICE LAB is a great fit for print-on-demand sellers on platforms like Etsy, Amazon Merch, Redbubble and Shopify, side-hustlers and shop owners who want a steady stream of niche designs, and hobbyists who love the theme but don't want to write prompts from scratch. If that niche is your lane — or one you want to test — this generator gives you an unfair head start.

What you get

Mutant Cuties: 60 animals × 40 creepy-cute mutations
150 spliced hybrids — axolotl-moth, possum-jellyfish, and friends
DNA & Lab wing: helixes, smiling petri colonies, brains in jars with bows
Kawaii horror, pastel goth, B-movie poster, trading-card styles
