How to Create Viral T-Shirts Faster Than Ever

About this video

RJ Martinez shows a fast way to create t-shirt designs using Kittl templates combined with ChatGPT, aimed at avoiding staring at a blank screen. In Kittl he browses templates, noting that likes and duplication counts signal what other creators are using, and searches by keyword — flowers in the demo — to find a design he likes, such as an ‘Always be kind’ floral design. He explains the template can be edited in place: changing fonts, swapping graphics (including with AI-generated art), and changing colors instantly. He then downloads a finished design and takes it to ChatGPT, asking for more ideas in the same style — in his example, three-word designs — and says ChatGPT returned three additional concepts along with the reasoning behind them, which he shows as phrases like spread good vibes, choose joy daily, and love wins always. He frames the pairing as Kittl supplying a proven template as inspiration and ChatGPT supplying variations, with back-and-forth prompting if the suggestions do not fit. For downloading, he shows setting width, height, and DPI, giving the Amazon Merch example of 4,500 by 5,400 pixels at 300 DPI, and removing the background before exporting. He closes by pitching the same approach for social posts and mockups and linking Kittl in the description.

Key takeaways

  • Start from a Kittl template instead of a blank canvas to speed up design work
  • Use likes and duplication counts on templates as a popularity signal
  • Feed a finished template design to ChatGPT to generate similar new design ideas
  • Edit fonts, graphics, and colors directly inside the Kittl editor
  • Export at 4,500 x 5,400 and 300 DPI for Amazon Merch, with background removed
