One line in, a rap out
AI Rap Generator
An AI rap generator that writes the bars, raps them over a beat and shows your photo performing them: a 12-second 9:16 vertical MP4 with AI-written lyrics, a rap voice and a beat. The generator below starts in Duo.
Your AI rap video

AI rap examples
One line, one rapper
Solo
Give it one line and the AI writes the rap. A solo performer in a yellow top delivers it at a hanging mic on an orange backdrop.
Hoodie rapper, one idea
Solo
A single idea is enough to start. A man in a black hoodie delivers the AI-written rap at a hanging mic in front of an orange backdrop.
Party topic, AI lines
Solo
Tell it the occasion and it writes to fit. A woman raps in the Living room party stage, with balloons and string lights behind her.
Two voices, one line
Duo
One topic line can feed two people. Two adults trade lines between sound-proofed walls and microphones.
Roast written for you
Rap Battle
The AI writes the roast as well. Two performers on an orange set trade playful jokes about burnt rice and thin soup.
Shared mic, one topic
Duo
A single retro microphone shared by two adults against an orange backdrop, the look of a quick topic turned into rap.
What an AI rap generator does
An AI rap generator does the part most people get stuck on: the writing. You give it one line about anything, such as a hobby, a rivalry or a bad Monday, and it writes the bars, picks the flow and raps them.
The rap is performed by the person in your photo. You upload 1 or 2 photos, and the AI turns them into a rapper who raps the AI-written bars in the video. The result is a 12-second 9:16 vertical MP4 with AI-written lyrics, a rap voice and a beat.
Rap works well for twelve seconds because it is built on rhythm and rhyme, and a good couplet fits the length. Switch to Solo for a single voice or to Battle for a face-off.

How to write a topic that rhymes well
The AI rhymes around the details you give it. A formula that works: a name, one quirk, one occasion. Then pick the mode that fits the topic.
Name + a quirk + an occasion
Three short facts give the AI three things to rhyme with.
- “Dana, who never stops talking, at the Friday team lunch”
- “Marco, allergic to mornings, on his first day at the gym”
Solo: a flex or a story about you
One photo, all 12 seconds.
- “Me, five years of side projects, finally shipped one”
- “Leo, undefeated at Monopoly night”
Duo: two people, one shared joke
Two photos, or one photo of both. You trade lines, then finish together.
- “Two roommates, one dishwasher, zero agreement”
- “Best friends and a road trip that lost its map”
Battle: a friendly rivalry
Two photos. One opens with a challenge, the other fires back.
- “Pineapple on pizza: Kim versus Jo”
- “Early bird versus night owl, settled in a rap”
Where an AI rap fits
Every result is a vertical MP4 with sound. A few places it works well, and what to do in each.
TikTok
Lead with the line that made you laugh while writing the topic, and keep the caption to one sentence.
Reels
Share the MP4 as it is, then ask a friend to answer with their own battle verse.
Shorts
Use the subject of the rap as the title. People find short clips by the thing they are about.
Stories
Tag the person in the video, so the rap goes straight into their notifications.
The group chat
Send it with no explanation. The rap says it for you.

A rap song maker that gives you a video
You write one line about a topic, and this rap song maker turns it into a 12-second rap song clip. The AI writes the bars and raps them in the video over a beat, so there is nothing to record and no verse to write first.
What you get from this rap song generator is a 9:16 MP4 with sound, in Solo, Duo or Battle. It is not an audio file and it is not a full-length song, but a short AI rap song clip is the right size to post on TikTok, Reels or Shorts.
Rhymes, flow and punchlines from one line
What sets an AI rap generator apart from a plain text writer is the rhyme. The AI looks for words that land on the same sound at the end of each line, then fits the line length to the beat so it can be rapped in time.
A good topic gives it something to rhyme around. “Gym at six, coffee at seven, nobody here is awake” has two time stamps and a mood, so the couplets write themselves. A vague topic gives vague bars.

How the AI rap generator writes the bars
The AI reads your line and writes a short verse in the rhythm of the beat you pick. Specific topics give better rhymes than general ones: “my cat knocking a glass off the table” beats “animals”.
The vocal is a generic AI rap voice. MKRap does not copy any real rapper’s voice, name or style.
Every run gives different bars, so if the first take is not funny enough, generate again with the same photo and a sharper line.

AI rap generator questions
Do I need to write any lyrics?
No. One line about the topic is enough, and you can leave it empty. The AI writes the bars.
Can I choose the beat?
Yes. You can pick Trap, Boom Bap, Old School or Drill before you generate.
How long is the rap?
Every video is 12 seconds long, so the rap is a short verse rather than a whole song.
Can it rap like a famous artist?
No. The voices are generic AI rap voices and MKRap does not imitate real artists.
How long does an AI rap video take?
Usually 3 to 10 minutes. You can close the page while it is made; the finished video is saved in My videos, where you can watch, download or share it.
How much does an AI rap video cost?
A pack is $9.90 for 1 video, $19.90 for 3 videos or $29.90 for 5 videos, as a one-time payment with no subscription. Each video uses one from your pack, and a video that fails is returned to your account automatically.
Does the video have sound?
Yes. The rap vocals and the beat are made by the AI together with the picture, so the MP4 plays with sound. There is no watermark.
