The free portrait exists so you can see what Heartgild makes from your own photo before spending anything. There is no account and no sign-up.
Try it with your best photo and a theme you like. If the result looks like your pet and you love it, save it and share it. If you want more themes, the paid options are there.
The free portrait works in any theme, so use it on the theme you are most curious about, such as Fine Art or Holiday.
Results are AI-generated. If your first one is not quite right, it usually helps to try a sharper photo.
