AI Lab
How to access: Click the AI Lab icon in the top-left corner of the Edit interface.
In the current UI, AI Lab is grouped by capability type. The main sections are Background & Scene, Remove & Repair, Subject Adjustments, and Enhance & Restore. Depending on the editing task, related portrait, background, and color panels may also show recommendation cards or search suggestions that help you find relevant AI Lab tools more quickly.
- Background & Scene: Tools for replacing or rebuilding the visual scene around the subject.
- Remove & Repair: Tools for removing distractions and repairing unwanted people or objects.
- Subject Adjustments: Tools for targeted subject refinements.
- Enhance & Restore: Tools for recovering, restoring, and improving image quality.
Batch Edit
Use Batch Edit to process multiple photos from AI Lab without entering each tool one by one. Select the photos you want to process, choose the AI effects to apply, and click Start to generate results in one workflow.
Batch Edit currently supports People Removal, Old Photo Restoration, and Detail Enhance.
Generative Expand
Use Generative Expand to extend the canvas and fill newly added areas while keeping the subject position and surrounding scene as consistent as possible. It is useful when you need to refine composition or prepare a different delivery ratio.
How to use
- Choose Original Ratio, Free Ratio, or a target ratio such as 1:1, 4:5, 5:7, 2:3, or 16:9.
- Set the four Expand Margins by dragging the canvas edges or entering values. Fixed-ratio settings keep the sides linked; custom values switch to Custom.
- Click Generate to create three results, compare them in the results list, and choose Save or Save All.
Saved results are added to the gallery as new images and can be expanded again for an iterative workflow. The Crop-Expand view displays the resulting ratio or pixel dimensions.
If the exact target size is not available, expand the image first and crop it afterward.
Background & Scene
AI Background Fusion
AI Background Fusion helps you create more complete and atmospheric scene-based portraits through intelligent cutout, background replacement, and layered foreground composition.
Batch Scene Workflow
AI Background Fusion supports saving a complete scene setup as a custom preset, including the background, foreground, subject placement, and crop. You can apply the same scene setup to selected photos and generate the final results in batches.
- Import a batch of photos into AI Lab > AI Background Fusion.
- Choose one photo, complete the scene edit, and save the result as a preset.
- Switch to Grid View to review multiple composites.
- Select the photos you want to process and use Batch Apply to apply the saved scene setup.

Strong Glare Removal
Use AI Lab > Remove & Repair > Strong Glare Removal to remove large glasses glare or bright lens reflections that regular glass glare removal may not fully cover.
- For group photos, select the person you want to process before generating the AI Lab result.

Use AI Lab > Belly Slimming to refine the waist and abdomen area with one click for a cleaner body silhouette.
- How to use: Click Generate, review the result in Results, and save it when you are satisfied.
- Suitable scenarios: Wedding, gown, portrait, and travel photos where the abdominal outline needs refinement.
Notes
- Some images may show weaker slimming, reduced clothing texture, visible skin texture changes on uncovered areas, or occasional unnatural abdominal definition.
AI Sky Replacement

Face Shadow Removal balances facial shadows, hard highlights, and stray light while preserving facial depth. Select a face in AI Lab > Subject Adjustments > Face Shadow Removal, then click Generate to create a result.

Golden Blonde Hair
Use Golden Blonde Hair to preview a natural, glossy blonde color on a selected person or face while keeping the hairstyle consistent. Open AI Lab > Subject Adjustments > Golden Blonde Hair, or open it from the Hair Color panel, select the person or face, and click Generate.
Body Hair Removal
Body Hair Removal detects visible arm hair and creates a mask for one-click removal while retaining natural skin texture. Open AI Lab > Subject Adjustment > Body Hair Removal, review the detected mask, and click Generate. You can also enter it from Retouching > Body Refinement. The feature is currently available in Asia.
Enhance & Restore
Liquify Background Repair
Use Liquify Background Repair to repair background lines and textures distorted by body liquify while keeping the subject adjustment. Open AI Lab > Enhance & Restore > Liquify Background Repair and click Generate.
For images with liquify distortion created in another application, use the repair-range control to refine the affected area.
Old photo restoration
Use AI Lab > Old photo restoration to repair old photos, enhance details, and optionally add natural color to black-and-white photos.
- How to use: Click Generate, compare the results in Results, and save the version you prefer.
- Default behavior: Colorization is enabled by default.
- Output: Supports standard 2K and 4K output.
- Suitable scenarios: Yellowed, faded, scratched, damaged, or blurry old photos.
Notes
- If faces are very small or the source image is extremely blurry, the model may redraw facial details. In some cases, accessories such as glasses or necklaces may also be affected.
Detail Enhance
Use AI Lab > Detail Enhance to improve image sharpness, texture, and fine details such as hair, facial details, and clothing patterns. Detail Enhance can also export higher-resolution results when the source image and final delivery needs require it.
Resolution options
- No Upscale: keeps the original image size and focuses on clarity enhancement. This is useful when the source image is already high resolution and only needs detail recovery.
- 2K, 4K, and 6K: enlarge the output to the selected resolution while enhancing detail. These options are useful for low-resolution sources, larger delivery sizes, or images that need more room for cropping.
When you enter AI Lab after cropping, available resolution options may depend on the current image size.
Notes
- Results may be limited on noisy, heavily blurred, or very low-resolution images.
- Very high-resolution images may show limited improvement or slight local consistency issues.
- Fine facial texture can look less natural if the source quality is too low or the upscale amount is too aggressive.
