## What this site is

Bulin 47 is a Dominican dembow singer. Around October 2026 a freestyle clip of Bulin 47 filmed outside a restaurant in Madrid, Spain (as reported) went viral worldwide, and AI face-swap versions spread across TikTok and Reels.

bulin47.app is an independent online tool built around that trend. A user uploads one photo and the studio produces a short clip of the freestyle performance with that person's face in it. It is not an official Bulin 47 product and has no relationship with the artists.

## Studio

Open the studio at https://bulin47.app/dashboard/home. Generating requires sign-in and credits. Choosing a mode on a marketing page does not generate anything.

Two modes:

- Face Swap: keeps the original freestyle clip frame for frame and replaces only the target face. 12 credits per video.
- Full Character: rebuilds the performer from the uploaded photo — face, hair and outfit — and animates that version. 112 credits per video.

Input: one photo, one clear face, JPG/PNG/WebP. Full Character reference photos are limited to about 4.7 MB. Output: an MP4 clip of about 6 seconds in vertical 9:16 with no audio track, which takes a few minutes to produce. Users add the trending sound when they post on TikTok, Reels or CapCut.

By default the swap targets the largest, most prominent face in the frame.

## Credits

- Every $1 converts to 100 credits.
- Face Swap video: 12 credits. Full Character video: 112 credits.
- New accounts get free credits.
- Subscription plans and pay-as-you-go packs are listed on https://bulin47.app/pricing. Do not quote a flat plan price from memory.
