How it works

  1. Upload your photo

    Choose a photo where your arms are clearly visible. Photos with good lighting and your arms not crossed or behind objects work best. The AI can work with selfies, group photos, or professional shots.

    Expect: Simple edits: 15-20 seconds. Complex lighting or poses: 30-45 seconds and may need refinements.

  2. Describe what you want

    Type your instruction like 'make my arms look slimmer' or 'tone my arms to look more defined.' No need to mark anything first - just describe the change you want. Be specific about whether you want subtle slimming, more definition, or both.

    Tip: Mention 'natural' or 'realistic' in your prompt if you want subtle changes that don't look over-edited

    Muscle definition Add muscle definition to my arms to show more visible tone and strength
    Try This →
    Proportional adjustment Adjust my arm size to be more proportional to my body frame
    Try This →

  3. Review the result

    Check that your arms look naturally slimmed without affecting other body parts. Zoom in to ensure the editing looks realistic around the arm area and clothing still fits naturally.

  4. Refine with markers if needed

    Optional: If the AI changed other areas you didn't want touched, tap markers specifically on your arms and regenerate. Most arm edits work perfectly with description alone.

    Tip: Markers are for precision when you want to edit one arm differently than the other, not a required step.

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which area you meant from description alone.

Try: Tap a marker on the specific arms you want to change, then regenerate with the same prompt
Try This →

Tip: Markers tell the AI 'I mean THIS arm specifically.' Use them when description alone is ambiguous.

Arms look too thin or unrealistic

Why: The prompt might have been too aggressive or the AI over-corrected.

Try: Try 'make my arms slightly slimmer while keeping them natural-looking'
Try This →

Tip: Add words like 'slightly', 'natural', or 'realistic' to prevent over-editing.

Only one arm changed when I wanted both

Why: One arm might be more visible or in better lighting than the other.

Try: Add markers on both arms and use 'make both my arms look slimmer'
Try This →

Tip: When arms are in different poses or lighting, markers help ensure both get edited equally.

Clothing looks distorted around the arms

Why: The AI reshaped the arm but didn't perfectly adjust the clothing fit.

Try: Add 'and adjust the clothing to fit naturally' to your original prompt
Try This →

Tip: Mention clothing adjustment when editing arms in tight-fitting tops or sleeves.

Arms look muscular instead of slim

Why: The AI interpreted 'toned' as adding muscle mass instead of slimming.

Try: Use 'make my arms slimmer and leaner' instead of 'toned'
Try This →

Tip: 'Toned' can add muscle definition. Use 'slim', 'lean', or 'slender' for pure slimming.

Background got distorted near the arms

Why: Complex backgrounds can be challenging when reshaping body parts.

Try: Try a more conservative prompt like 'subtly slim my arms'
Try This →

Tip: For busy backgrounds, start with subtle changes and build up if needed.

Quick answers

Do I need to mark my arms before describing what I want?

No! Just describe what you want like 'make my arms slimmer.' The AI will automatically detect and edit your arms. Only use markers if you need to be very specific about which arm or if the first result wasn't quite right.

Will the arm edits look natural and realistic?

Can I edit arms in group photos without affecting others?

Yes! The AI can focus on specific people in group photos. If it edits the wrong person, use markers to point to your arms specifically, then regenerate with the same prompt.
