The Bulin 47 AI trend started with a short phone video outside a red-lit doorway in Madrid. A Colombian creator with a speaker starts freestyling dembow at the Dominican artist Bulin 47, and instead of walking past, Bulin stops, talks back and laughs. Within a week people were putting footballers, actors, their friends and themselves in Bulin's place.

The short answer
The Bulin 47 AI trend is a wave of fan remakes of a street freestyle filmed in Madrid in early October 2026, where the creator Kevin Wai, known as Kevincito, raps about the artist Bulin 47 on the spot. People upload one photo and an AI tool makes them the star of the scene, in Bulin's spot. On AI Rapping the freestyle can also be about you, with your own words.
Three frames from a Bulin 47 sample we made with our own template in October 2026. The original song is not included.
Who Bulin 47 is
Bulin 47 is the stage name of Hancel Teodoro Vargas Reynoso, a Dominican singer, songwriter and comedian born in 1989. He has been releasing urban music and dembow since 2016. His best known songs include "7 Pollos", and he has worked with Myke Towers ("Mi Tranza") and Pitbull ("Party").
That background explains a lot of the clip. Bulin is a performer who is also funny on camera, so when a stranger starts rapping at him he plays along instead of brushing it off.
One night in Madrid
The original clip is simple. It's night, there's a red-lit entrance, security and a small crowd. Kevincito follows Bulin with a phone in one hand and a speaker playing a dembow beat, and freestyles about him as he walks up. Bulin answers back, gestures, and breaks into a laugh. That is the whole video.
A timeline put together by the fan site bulin47viral.com dates the clip to October 2, 2026, with both men posting it on TikTok within half an hour of each other. We haven't been able to confirm those times from a second source, so take the exact date with some caution. By the same timeline, Bulin 47 put out the official video for "Dame Hombro" on his YouTube channel six days later, and Spanish-language radio was reporting on the clip that week. Either way, it moved fast.
The first week of AI remakes
The AI versions showed up within days. The format copies everything except the person: the doorway, the crowd, the handheld camera, the hype man with the speaker, even Bulin's laugh. People cast footballers and actors first, then politicians, then whoever they wanted to tease.
You'll see it called the Bulin 47 freestyle, the Kevincito freestyle trend, the club door freestyle or just Bulin 47 AI. Most of the clips on TikTok carry the same few hashtags: #bulin47, #bulin47freestyle and #bulin47challenge.
Why it travels so well is easy to see. The clip is short, the reaction is warm rather than awkward, and the joke works in any language because the reactions do most of the work.
Getting a freestyle about you
Almost every remake keeps Kevincito's original words, so the person in the middle is getting a freestyle about Bulin 47. That's fine for a quick post, but it's the part we changed.
The Bulin 47 AI video template on AI Rapping has two modes:
The template page: add your photo, pick Silent remake or Your own rap, tick the photo consent box, then press Make my AI rap video.
- Silent remake: you take Bulin's place in the scene, with no audio, so you can add the sound in TikTok. You get a vertical video for 10 credits.
- Your own rap: you say what the freestyle is about and it is rapped about you, with the lips matched to the words. It costs 10 credits.
If you'd rather not write the lines yourself, start on the homepage with the AI rap generator. Type something like "my cousin thinks he's famous because he has 400 followers", pick Trap or Diss, and you get lyrics in about 8 seconds and a 30-second song to listen to. Your first song is free when you sign up. Take the two lines you like best into the template.
The AI rap generator on our homepage. One sentence in, lyrics and a song out; every line can be edited.
A few lines in the spirit of the original, to change a word or two:
- "Pulled up to the door and the line went quiet"
- "Security nodding, they already know my name"
- "Speaker in my ear and the whole block's on it"
Credit packs start at $9.99 for 10 credits and don't expire, and a failed video gives its credits back automatically. See pricing for the other packs.
A photo that matches the night
The camera is close on the face, so the photo matters more than the outfit.
- Use a front-facing photo with your eyes visible and your chin level.
- Photos taken at night or in warm light sit better under the red light than a bright beach selfie.
- One person per photo. A group shot confuses the tool.
Doing it without being a jerk
The original works because two strangers were kind to each other on camera. The remakes that keep that tone, a friend getting hyped up, read better than ones that use the format to mock someone. Only put someone in the video if they agreed to it; you confirm you have the right to use the photo before anything is made.
