Bicep Heart AI

Bicec​h Heart AI lets you turn a single portrait into a short video that follows the “bicep heart” pose popular on X and TikTok. You upload one clear photo of a consenting adult, and the service returns a vertical 9:‑16 MP4 that lasts about seven seconds. The output is 480p video with background music, ready for you to add your own licensed track if desired.

The tool is aimed at creators who want a quick, no‑recording way to join the bice‑heart trend. It works with JPG, PNG, WebP or browser‑supported HEIC files up to 40 MB, though the upload itself is limited to 10 MB. The photo must show the head, waist and both arms; short sleeves help the algorithm place the hand correctly. After you pick a video pack (1,  3 or 5 videos), you sign in with Google or an email, pay, and the generation starts, paying never triggers a video before you confirm the photo. The resulting file is stored privately for seven days, while the original image is deleted after 24 hours.

The process is three steps: choose a suitable portrait, select a one‑time video pack, and click “Flex. Heart. Send.” The site runs the transformation locally before uploading, so large files are prepared on your device. The final video includes silent background music, but you can replace it with any licensed audio when posting. Results can vary in arm proportions and facial expression, and the system does not guarantee perfect finger placement. The service is independent, not linked to Tik‑Tok or MakeViral, and is offered in English and Chinese.
