Frequently Asked Questions

Common questions about making custom t-shirt designs with AI on NightCafe

Is the custom t-shirt generator free to use?

Yes. NightCafe provides free daily credits so you can generate t-shirt graphics without entering payment details. Paid plans offer more daily credits and access to premium features if you need higher output.

Can I use the AI-generated t-shirt designs for selling merch or print-on-demand?

Yes, including on the free plan. NightCafe assigns copyright of the generated image to you as the creator, so you can use designs commercially — for merch drops, print-on-demand stores, event tees, or anything similar. You should own or have permission to use any reference images you upload. AI copyright law is still evolving and varies by country, so it is worth checking the rules in your jurisdiction.

Which AI models are available for t-shirt design?

NightCafe offers 30+ image generation models including Nano Banana, GPT Image, Flux, Seedream and more. Different models suit different tee aesthetics — some excel at bold linework and vector-adjacent graphics, others at painterly or photorealistic results. You can switch models without losing your prompt.

Do I need to sign up to generate a t-shirt design?

No account is required to get started. You can generate art immediately using free daily credits. Creating a free account lets you save your designs, build a gallery, and join the NightCafe community to share work and get feedback.

How is NightCafe different from Canva or Midjourney for t-shirt design?

Canva focuses on template-based design editing rather than AI image generation. Midjourney generates images but is Discord-only and has no built-in creative community. NightCafe combines 30+ AI models, image-to-image refinement, and a social community in one place — making it easy to go from idea to shareable tee graphic without switching tools.

What file format will I get, and can I send it to a printer?

NightCafe generates high-quality raster images you can download and send to most print-on-demand services or local printers. For best results on fabric, describe your design with clear contrast and a clean background in your prompt — the generator responds well to those instructions.
