Upload two photos — one per performer — and let the AI drop them into the viral rap-duet trend in seconds.
Your video may be selected and published to the public Explore feed to inspire other creators.
Two photos in, one viral rap-duet clip out. Our AI reads both faces, rebuilds them in an On the Radar-style live radio studio, and animates the pair trading verses — no editing skills required.
Upload Two Performer Photos Default mode takes two separate photos — one per performer — for the strongest identity match. Prefer a single frame? Switch to One Photo and upload a shoulders-up, side-by-side shot of both subjects.
Pick a Stage On the Radar Live for the trend-accurate dark radio studio, Neon Smoke Cypher for an underground look, Chrome Studio for a premium showcase, or 90s VHS Broadcast for analog nostalgia.
Generate & Share Click Generate and get a 5-second rap-duet clip with audio. Aspect ratio defaults to Auto — switch to 9:16 for TikTok, Reels, or Shorts.
The Fetty Wap 679 AI trend is the viral video format that took over TikTok, Reels, and Shorts in late 2026. It started when creators used AI to place two subjects — themselves and a friend, two pets, even cartoon characters — into a recreation of the famous live radio-show rap duet: two performers standing side by side, trading verses over their own microphones with hyped, crowd-level energy.
Our generator recreates that exact look from your photos. Upload two separate portraits — one per performer — or a single picture with both subjects in the frame, pick a stage, and the AI rebuilds the scene around them: the studio, the microphones, the synchronized bounce, and a generated trap audio track. Everything is original AI generation, so the clip is yours to post wherever you like.
Most 679 tutorials push you through three or four different apps — one to cut out the subjects, one to generate the video, one to add the audio. This template does the whole job in one place. Upload, click Generate, and 30–90 seconds later you have a finished 5-second rap duet with sound, ready to download in MP4.
It is free to start: new accounts get free credits, a 5-second 480p clip costs just a couple of credits, and the exact price is always shown on the Generate button before you click. There is nothing to install — the generator runs in your browser on desktop and mobile. And because the model treats your photos as strict identity references, both performers keep their faces, hairstyles, and proportions instead of melting into generic characters.
The classic play is you and your best friend trading verses — but the format stretches much further. Drop in your dog and your cat as the two performers, swap a celebrity photo next to your own (where you have the rights to use it), or cast two fictional characters as an unexpected duo. Pets performing the duet with chaotic enthusiasm is one of the most-shared variants of the trend.
Small teams use it too: two coworkers doing a farewell duet, podcast hosts announcing a new episode, a founder pair celebrating a launch. Because every clip is original AI generation rather than a re-uploaded music video, it stands out in a feed full of direct copies — and commercial use is on the table where platform rules allow.
Start with the photos. In Two Photos mode, use matching shoulders-up portraits with even lighting — same framing, same quality — so both performers lock in evenly. Avoid sunglasses, heavy shadows, and subjects half out of frame; those are the mistakes that break most attempts at this trend.
Then match the stage to the energy you want. On the Radar Live is the trend-accurate look; Neon Smoke Cypher and Chrome Studio give your edit a fresh twist that stands out among copies. Leave the aspect ratio on Auto to match your photo, or force 9:16 for TikTok and Reels. If the first take misses, adjust the photos or stage and regenerate — every run is independent.
Upload two photos — one per performer — and let the AI drop them into the viral rap-duet trend in seconds.
