Hama

Based on the available evidence, Hama looks adoptable as a lightweight online image cleanup tool, not as a core tool for professional retouching workflows. What the sources support is straightforward: you upload an image, brush over unwanted areas, and the tool fills the background automatically. Multiple Chinese-language mentions frame it as easy to access, low-friction, and suitable for quick one-off edits. That supports a positive adoption judgment, but the sample size is small and lacks rigorous comparative testing.

Its practical role is not online background cutout, not layered editing, and not a true Photoshop replacement. A better analogy is “a browser-based AI healing brush / content-aware erase tool.” It seems best for removing passersby, clutter, small blemishes, or simple watermarks, with the main output being a cleaner image ready to share or continue editing elsewhere. The Zhihu article and answer both emphasize ease of use and visually natural removal, but there is not enough evidence to conclude that it performs consistently well on complex scenes, fine edges, or commercial-grade retouching.
