How to Do the AI Rap Duo Trend on TikTok (Step by Step)

The short answer: to do the AI rap duo trend, turn two photos into a short rap video of two people, download the vertical MP4, and post it with a short caption and TikTok's AI-generated label. With airapvideo the whole thing takes about 10 minutes, including about 3 to 5 minutes of rendering.

What is the AI rap duo trend?

Two people, often friends, a couple, a parent and kid, or a person and a pet, appear on a stage together and rap a short verse. Neither of them filmed anything. The clip is made from two ordinary photos, which is exactly why it is funny: people who would never rap on camera are suddenly doing it.

Step 1: Pick the duo

The best duos have contrast: the loud friend and the quiet one, a grandparent and a teenager, you and your cat. If you need ideas, see 12 AI rap video ideas.

Step 2: Pick the photos

You need one photo of each person:

  • One person per photo, cropped tight enough that they are the clear subject.
  • Face sharp and visible, roughly facing the camera.
  • Similar framing in both photos, for example two waist-up shots.

Step 3: Create the video

  1. Open the generator in your phone or desktop browser. There is no app to install.
  2. Upload both photos. The person on the left leads the verse; the right side hypes.
  3. Click Create. There are no prompts or settings.
  4. Wait about 3 to 5 minutes. Every video is 10 seconds in vertical 9:16, the native TikTok format.
  5. Download the MP4. It has no watermark.

You do not need an account to start. A single video is $9.90; packs of 3 and 5 are on the pricing page.

Step 4: Post it on TikTok

  1. Upload the MP4 to TikTok.
  2. Turn on the AI-generated content label in the post settings. TikTok asks creators to label realistic AI content, and it is honest with your viewers.
  3. Write a short caption (ideas below).
  4. Add a few relevant hashtags, such as #airap or #rapduo, plus one for the occasion (#birthday, #bestfriend).
  5. Tag the other person if they are on TikTok. Their repost is often where the views come from.

What should I write in the caption?

  • "We've never rapped a day in our lives. Until now."
  • "Me and my best friend after one coffee."
  • "My grandma has bars. Who knew."
  • "The duo nobody asked for."
  • "Happy birthday to my day one 🎤"

Someone laughing outdoors: the reaction is the point

How do you get more views on an AI rap video?

  • Hook in the first second. The caption on screen should tell people who the two are.
  • Post the reaction too. Film the other person watching it for the first time and post it as a follow-up.
  • Make a series. One duo per day for a week, with the same caption format, gives people a reason to follow.
  • Same video, three platforms. The vertical MP4 works on TikTok, Instagram Reels and YouTube Shorts without editing.

What rules apply to AI rap videos?

  • Only use photos of people who agreed to be in the video.
  • Children should only appear if you are their parent or legal guardian.
  • Label it as AI-generated.
  • The music and vocals come from a built-in rap performance; you cannot add your own song, and results vary between renders.
