How our AI shirt design generator works

Create shirt designs with ease. Provide an input and let the system do the creative work.

  1. 1

    Get an idea for a shirt

    Out of ideas? Enter something random and ask the AI to be creative. You can also drag and drop a reference image and build the design around it.

  2. 2

    Enter your prompt

    Your prompt can be a single word — the system is built to be creative on your behalf. More detail and clarity still gives better results.

  3. 3

    Edit the details

    Spot an imperfection? Modify the design: its words, fonts, colours and the position of every element. You control the entire layout.

  4. 4

    Download your design

    On download the artwork is exported clean at print resolution. You get two versions of the design — with and without a background.

An AI generator specialised in t‑shirt design

TeeForge is a shirt design generator built by print‑on‑demand sellers. It makes custom designs for tees without the heavy manual work, and its image reference mode produces template‑driven designs at scale.

Licensed for commercial use

Every design you produce with TeeForge is cleared for commercial use — sell it on any platform you like.

Print-ready designs

Export clean HD files at 4500×5400px with crisp edges, ready to upload straight to a POD platform.

Produce in bulk

Parallel generation lets you create a batch of designs at once instead of waiting on a queue.

Finishing tools built in

Background removal, distress textures, a rotated halftone dot screen, and a resolution upscaler — all in the same editor, no separate app.

Better than a general AI image tool

Same prompt, very different output when the target is a garment.

FAQ

Common questions about TeeForge, answered.

What type of shirt designs can TeeForge create?

Typography lockups, vintage badges, vector graphics, streetwear layouts, graffiti lettering, psychedelic posters, emblem logos and retro vaporwave scenes. Anything you can describe in a prompt, in a layout that suits the front or back of a tee.

Can TeeForge generate a design based on an image?

Yes. Drop an image into the prompt box and pick a model that can read an image (GPT Image, Nano Banana or Grok, plus FLUX.2 Pro and Seedream on fal.ai): TeeForge sends the design itself to the model and asks for a brand-new design in the same style — same layout, lettering treatment, palette and effects — with the content from your prompt. The Reference image button appears only while one of those models is selected, because the others cannot take an image.

Can TeeForge create a design similar to an existing one?

It can match a look — a layout family, a palette, a lettering treatment — so a collection stays consistent. Style matching asks the model to replace every name, word, logo and person from the reference with your new content, but you should still only upload references you have the right to use and check the result before selling it.

Do I get transparent background designs?

Every download gives you two PNG files: one on the background colour you chose and one with the canvas background left transparent. Note that a generated bitmap still carries whatever background the model drew behind the artwork — cutting that out is a separate background-removal step.

Can I use the designs on print-on-demand platforms?

Yes — designs are licensed for commercial use and exported at 4500×5400px, which clears the resolution requirements of the major POD marketplaces.

What does it cost?

TeeForge itself is free and has no account. Image generation runs on your own provider API key, so you pay that provider directly at their rates — nothing is marked up in between. The editor, the layout tools and the exports cost nothing and run entirely in your browser.
