About BicepHeart

What we make

BicepHeart is an independent tool that turns one photo of a consenting adult into a short AI bicep heart video. The movement is simple: smile, lift and flex one arm, and curl the other hand against the bicep to form a heart. You do not need to write a prompt or film the gesture yourself.

How the tool works

We use Genjutsu 1.0 motion transfer through NanoAPI at 480p. Your photo supplies the person and an authorized movement reference supplies the action. The output is a short MP4 of variable length without an added watermark or audio track. A portrait photo with both arms in view works best. Hands, likeness, clothes, framing and the room can vary; examples show the intended effect rather than a guarantee of an identical result.

NanoAPI describes Genjutsu 1.0 as a motion-transfer model fine-tuned from Seedance 2.5. Our integration calls NanoAPI's genjutsu-1.0 model; BicepHeart is an independent application using that service.
