T-Shirt Design AI — AI t-shirt design generator for POD sellers and creators. Turn a sentence into custom tee graphics — print-ready 300 DPI PNG, live shirt preview. Free trial.
TshirtDesignAI is an AI t-shirt design generator that turns a text prompt or a reference image into production-ready T-shirt artwork.
Describe your idea in plain English — subject, style, mood, slogan — and the AI handles composition, accurate slogan text, and clean edges. A polished design lands in 60–90 seconds, previewed live on the shirt: switch between 6 garment types and 12 garment colors instantly in the browser.
Choose from 9 art styles including vintage retro, bold typography, cartoon mascot, line art, grunge streetwear, kawaii chibi, emblem badge, watercolor and Y2K. Upload a reference image and the generator restyles it while keeping your original idea.
Export a transparent 300 DPI PNG at 4500x5400, sized for standard DTG and screen-print areas with safe margins. The background is removed with a semantic segmentation model, so edges stay clean even on detailed artwork. No watermark.
Built-in Studio mode handles bulk generation: set one theme, paste a list of slogans, pick styles, and batch up to 20 designs in parallel. Failed designs are refunded automatically.
Free trial: your first design and its print-ready file are free after Google sign-in, no card needed.

What do DR4, DR3 and the model difference mean?
DR4:
Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
DR3:
The previous model, shown in the Ahrefs app until 1 December 2026.
Model difference:
DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
