A t-shirt design is merchandise, so the first question for a free AI generator is whether the free plan lets you sell what it makes. Playground's free plan includes "Commercial use – World-wide, royalty free license". Adobe Express says generative AI outputs can "in general" be used commercially, and marks transparent PNG export as free. Kittl's free plan is "For personal use only". Recraft's free-plan images are "owned by Recraft" and "not licensed for commercial use". On 8frame, a design plus a transparent cutout costs about 18 to 33 credits, with commercial use on paid plans.
TL;DR
| Tool | Sell from free? | Transparent export on free | Cheapest paid |
|---|---|---|---|
| Playground | Yes: "Commercial use – World-wide, royalty free license" | Not stated; SVG export not on free | Pro $15/month, $12 billed annually |
| Adobe Express | "In general", yes | Marked available | Premium, 250 generative credits a month |
| Kittl | No: "personal use only" | Not on free | Pro $15/month |
| Recraft | No: "not licensed for commercial use" | Not stated | Basic $12/month, $10 billed annually |
| 8frame | Yes, on paid plans | Background removal returns a PNG cutout | $19/month, 1,000 credits |

The picks
Playground: commercial use on the free plan
Playground's free plan card lists "Commercial use – World-wide, royalty free license", and its FAQ says "You own the images you create on Playground. You can use them for personal or commercial use (YouTube, Etsy, Instagram, etc.), as long as you follow our terms." The allowance is stated two ways on the same page: the card says "Create up to 10 images every 3 hours", while the comparison table says 5 per 3-hour window, with 2 downloads a day. SVG export is not on free. Pro is $15 a month, or $12 a month billed annually, and adds SVG exports.
Adobe Express: transparent PNG and commercial terms on free
Adobe Express offers free daily generations and marks "Export as PNG with transparent background" as available on the free plan. On use it says: "In general, you may use outputs from generative AI features commercially", except beta features Adobe designates as personal use only. Premium adds 250 generative credits a month.
Kittl: built for merch, but not free for merch
Kittl gives "100 AI tokens / one time", about 20 images, and its free plan is "For personal use only (no commercial rights)". Transparent and high-resolution exports are paid features. Pro is $15 a month with 2,000 AI tokens a month, "High resolution exports for print & digital" and a "Full commercial license". Good for designing; upgrade before you sell.
Recraft: vector styles, paid plan to sell
Recraft's free plan gives limited daily generations, but "Images generated on the Free plan are owned by Recraft. They are publicly visible in the community gallery and are not licensed for commercial use." Basic is $12 a month, or $10 billed annually, for 1,000 credits with "Commercial rights and private generations".
8frame: design, cut out, check the lettering
On 8frame, generate the design on a plain background, then remove the background:
- Design: Seedream 5 Lite at 6 credits for graphic ideas; Nano Banana Pro at 21 when the shirt has words, the model we recommend when words must be spelled right.
- Cutout: background removal, 12 credits, returns a PNG.
- Size: BRIA enlarges 2x or 4x for 6 credits, up to 8192 x 8192.
About 18 credits for a graphic, 33 with lettering. There is no vector output on 8frame; if your printer wants vector files, vectorize the final design. Commercial use is cleared on paid plans. The canvas is free and unlimited; generation is paid from $19 a month.
Before you print
- Ask your print provider for their file spec. Print-on-demand services set their own size, resolution and format requirements.
- Limit the colours if the design will be screen printed; each colour is a separate screen.
- Check the cutout edge. Halos from background removal show on dark shirts.
- Don't use brands, logos or characters you don't own. A generator won't stop you; a marketplace takedown will.
