The route

From prompt to listing in four stops

1

Generate it flat

Ask ChatGPT for bold shapes and solid colors on a transparent or solid black background. Leave knit texture out of the prompt.

2

Drop in the batch

Add every design at once. Turn on Upscale for small AI images and "Remove background" if the background is baked in.

3

Check the details

Open any design at actual pixels. Look at thin letters, snowflake arms and tree trunks.

4

Download & list

Grab transparent PNGs as one ZIP and upload them to your POD provider. Dark shirts show the knit best.

FAQ

Questions

Is it really free?

Yes. No watermark and no limits. You enter your email once before your first download, and that's it.

Do my designs get uploaded anywhere?

No. Everything happens in your browser on your own computer. The AI upscaler downloads a small model the first time, then runs locally too.

What kind of art works best?

Flat, vector-style art with bold shapes and solid colors: lettering, snowflakes, trees, hearts and simple characters. Busy, shaded or photographic images lose detail when stitches are cut in.

Why are some stitches cut off at the edges?

On purpose. The stitch pattern is laid over the whole design and cut wherever the art ends, which is what makes it read as knitted instead of printed.

Which shirt colors work best?

Dark shirts show the stitch gaps most, like a real sweater. Use the shirt swatches in the workspace to preview before you download.

The AI upscale is slow or won't start.

It uses your computer's graphics chip. Chrome or Edge on a laptop or desktop works best. If it can't run, Knit Studio switches to the Fast upscaler automatically.
