Enhance

AI post-processing for your images — one-click Handfix, Face Fix, Change Emotion, Background Remover, Convert to Line Art, Sketch Coloring, and filters.

Image enhancement runs post-processing on images you've already generated — fix flaws, refine details, or shift styles without rerunning generation. It splits into Preset tools and Filters.

Preset Tools

ToolUse case
HandfixDetects hands and inpaints locally — fixes extra fingers and twisted joints
Face FixDetects faces and redraws them — handy for distant shots, group scenes, side angles
Change EmotionKeeps the character's identity, only changes the expression (smiling, surprised, shy, etc.)
Background RemoverStrips the background and exports a transparent PNG — good for character standee assets
Convert to Line ArtTurns colored images into line art, usable as a ControlNet reference
Sketch ColoringAuto-colors black-and-white line art

Filters

Apply color-style filters to shift the overall tone. Seven presets are available right now (Filter M1–M7). Pick an image and preview live — save or publish once you like the result.
