Bulin 47 AI Video: Make Your Own Street Freestyle Duo
A Bulin 47 AI video is an AI remix of the viral street freestyle between Dominican artist Bulin 47 and Kevin Wai, usually made by swapping new faces into the original clip. Here you can make your own original version instead: upload two photos, pick a night street scene and get a duo freestyle with fresh lyrics, an original beat, two voices and lip-sync in about 3 minutes.
Independent tool, not affiliated with Bulin 47 or Kevin Wai. We never use the original clip, song or voices.

The backstory
Where did the Bulin 47 trend come from?
It began as a real, unplanned moment, not an AI clip. Outside a restaurant in Spain, Kevin Wai walked up to Bulin 47 with a portable speaker playing a dembow beat and started rhyming. Bulin stopped, rhymed back and added a shoulder dance that became the signature of the video.

Bulin 47 face swap vs. your own AI freestyle
Most Bulin 47 AI videos paste a new face onto someone else's footage. We take a different route and generate a brand-new performance from your photos.
| Face-swap remix | AI Rap Videos | |
|---|---|---|
| Video | The original street clip with a new face pasted in | A new video of you and a friend, generated from two photos |
| Music and voices | The original song and voices, reused | An original beat, original lyrics and two new voices |
| Who appears | Often celebrities who never agreed to it | Only adults who said yes, usually you and a friend |
| Lip-sync | New faces mouth someone else's words | Each person raps their own lines in sync |
| Posting | Reused footage and audio may get muted or claimed | Original from start to finish, sized for TikTok, Reels and Shorts |

What is a Bulin 47 AI video?
A Bulin 47 AI video is an AI-made remix inspired by the viral street freestyle of Dominican artist Bulin 47 and Kevin Wai. Most remixes swap a new face into the original clip. AI Rap Videos takes another approach: it creates an original duo rap video from two photos, with new lyrics, an original beat, vocals and lip-sync.
Is there an official Bulin 47 AI app?
Not that we know of. AI Rap Videos is independent and not affiliated with, sponsored or endorsed by Bulin 47, Kevin Wai or their teams. Sites that use the name are describing a trend, not an official product.
Can I use Bulin 47's face or a celebrity's?
No. Upload only photos of yourself or of adults who agreed to appear. Photos of celebrities, public figures or anyone without consent are not allowed, and we never imitate an artist's voice or lyrics.
How long does it take, and what do I get?
About 3 minutes from photos to finished video. Each video comes with:
- 8 to 15 seconds, up to 1080p
- 9:16, 1:1 or 16:9 for every major platform
- A rap in English or Chinese with two distinct voices
- A free watermarked preview before you pay, no subscription needed

AI rap video FAQ
Everything you need before your first video.
Will both people rap?
Yes. The two performers take turns line by line: odd lines go to the first photo (or the person on the left in a shared photo) and even lines to the second. To change who starts, swap the photos.
Can I include names, birthdays or inside jokes?
Yes. Add them to the topic or to your own lyrics. Keep the topic short, around 40 characters. Birthday, how-we-met, cooking and team-win topics each get their own verses.
Can I use my own lyrics?
Yes. Paste up to 8 lines, with 300 characters in total and 80 per line. The performers are asked to rap them once, exactly as written, though an AI performance can still drift slightly. Lyrics copied from existing songs are not allowed.
How accurate is the lip sync?
Mouth movement follows the generated vocals line by line. Short, clear lines sync best; very fast or tongue-twisting bars are harder, so results can vary from one take to the next.
Will the performers look like our photos?
They are based on your photos, but the video is generated, so faces, hands and small details can vary. Sharp, front-facing photos with even light give the closest likeness.
Does the video include lyric captions?
Yes. Rap videos have the lyrics burned in as captions, in the preview and in the final video, and they cannot be turned off. Photo effects have no captions.
What lengths, resolutions and aspect ratios are available?
Rap videos are 8, 12 or 15 seconds and photo effects 5 or 10 seconds. Choose 480p, 720p or 1080p (1080p with Pro and Ultra) and a 9:16, 1:1 or 16:9 frame. Downloads are MP4 files.
What is the difference between Standard, Fast, Pro and Ultra?
They are different video models: Standard is balanced, Fast favours speed, Pro adds detail and Ultra is the premium option. The price depends on the model, resolution and length, and the creator shows it before you generate.
