Frequently Asked Questions

1. How does AI background replacement work?

Our AI first removes the existing background from your photo, then generates a new background based on your text description. The subject is seamlessly composited onto the new AI-generated scene.

2. What kind of backgrounds can I create?

Anything you can describe! Office settings, beach scenes, studio backgrounds, city skylines, nature landscapes, futuristic scenes — the AI generates any background from your text prompt.

3. Is this better than using Photoshop to change backgrounds?

For quick changes, yes. Our AI handles edge detection, hair detail, and lighting matching automatically. No manual masking or layer work required. It takes seconds instead of hours.

Yes! Try prompts like "soft gradient studio background, professional lighting" or "modern office with large windows." Great for LinkedIn, resumes, and corporate profiles.
