PicDoai lets you step into any scene using a single full-body photo. Choose a ready-to-use template or upload your own video, then replace one character while keeping the original motion from the clip. Whether you’re recreating trends, making funny edits with friends, or crafting fan scenes, PicDoai makes it fast, simple, and shareable. What you can make • Template Swap: Pick a template, upload one full-body photo, and step into the scene by replacing one character. • Custom Swap: Upload your own video and one photo to replace a selected character for fully custom results. • Motion Transfer: The swapped character follows the motion from the source video for natural, dynamic results. Why creators love it • One-photo setup (full-body recommended). • Replace one character precisely and quickly. • Template library + custom uploads for flexibility. How it works 1. Upload a clear, front-facing full-body photo. 2. Choose a Template or Custom workflow, then select the target person to replace. 3. Preview the motion-transferred result, export, and share. Safety & Respect Only upload content you own or are authorized to use. Don’t impersonate real people without consent or misuse copyrighted material. PicDoai does not support watermark removal or illegal uses. Follow local laws and platform rules. Support Questions or feedback? Contact us via the in-app Help & Feedback.
