Hey Product Hunt! I'm Alex, the creator of Genjutsu AI. **The problem**: Editing a video you already shot is painful. Need the same take but with a different person, outfit, product or location? You reshoot. You track masks for hours. You give up and post the original. **Our solution**: Genjutsu AI keeps what made the clip work — the motion, the camera, the rhythm — and changes what you need. Upload a 2–15s clip, pick a mode, and get a new take back. **The name**: 幻術 (Genjutsu) is the art of illusion. That's exactly what this is — the performance is real, the reality around it is crafted. **What makes it special**: - 7 modes: Motion Transfer, Character Swap, Outfit Swap, Object Swap, Background Swap, Restyle and Face Swap - Style preserved — photoreal stays photoreal, cosplay-grade anime stays anime - Motion, camera path and timing from your source clip are kept - Sound matched to the edit by default; editing modes can keep original audio - 196+ built-in templates to start from **Why I built this**: I kept watching small creators do what used to take a VFX team — and it looked like magic. I wanted that to be a normal upload, not a studio budget. I'm here all day — what would you cast first? 🎬
