youka Dec 8, 2025 v@ initial release

Tried to fix a cropped travel photo and it worked great. The AI naturally expanded the sky and beach, so the image fit a 16:9 YouTube thumbnail without any visible seams or quality loss.

Janus Jansen Nov 30, 2025 v@ initial release

Tried an image of a person. Just the head and shoulders, the AI had to extend the body. Result: different shirt color, six fingers.
C'mon, it's almost 2026, we can do better than giving a person six fingers and not understanding the shirt color.
