I wrote about stylised qr codes before but not many simple online interfaces were live back then. Well sure enough couple of months later this change big time.
Most recent I found, and which is quite simple and intuitive to use is QR Diffusion. It does still have some bugs - generated codes not working all the time - but still is useful and simple tool.
Well, yes, it does exactly what you are thinking of ...
QR Diffusion helps you turn ordinary QR codes into artful designs. It uses Stable Diffusion and ControlNet to do so, and is build on a solid and simple UI interface for everyone to use and understand.
This tool creates unique, scan-friendly QR patterns.
You can personalize your code with logos, adjust dot styles, and select from a variety of AI templates, including anime and landscapes.
It's user-friendly; input details, customize, and get a special QR code quickly.
The website also offers tutorials and support.
