The short answer
To make a birthday rap song, add a photo of the birthday person and a photo of you (or one photo with both of you), tap the Birthday chip and type their name, their age and one thing everyone knows about them. The AI writes original lyrics, makes the beat and two AI voices, and renders the two of you rapping it, lip-synced, in about 3 minutes. A standard 12-second 720p video is 10 credits; the $9.99 Single pack covers one, and 5 songs cost $29. There is no free preview, and a failed render is never charged.
A birthday rap made about one person
Most birthday songs are written for anybody. A birthday rap made here is written for one person: their name is in the lyrics, their habits get a gentle ribbing, and they are on screen performing it with you. You do not film anything. Two ordinary photos and a single line are enough for the AI to write the verses, build the beat and animate both faces so the mouths move with the words.
The result is a short vertical video you can drop in the family chat, post on their birthday morning, or play on the TV at the party. It works in a phone browser, so you can make it on the way there.
How to make a happy birthday rap video
- Add the photos. One clear photo of the birthday person and one of you. If you have a good photo of the two of you together, use that instead. Going it alone? Pick Solo and the birthday person raps by themselves.
- Write the birthday line. Tap the Birthday chip, then add a name, an age and one specific detail, up to 120 characters. Specific beats general every time.
- Choose a stage. The orange Hotel Lobby is the look people know from the trend. Luxury Lobby feels a bit fancier, Studio Booth a bit more serious.
- Make it and send it. Tap "Make our rap video". In about 3 minutes the MP4 is ready to download and share.
Prefer something sung and sweet rather than rapped? The personalized birthday song page makes a sung birthday song with their name in it.
Birthday rap ideas you can type
Copy one of these into the topic box and swap in your own names and details:
- For a best friend: "Happy birthday Nina, 27 today, still my plus-one to every wedding"
- For a brother: "Marcus turns 21, finally old enough, still asks Mom to book his haircuts"
- For a partner: "Happy 32nd Sam, you burn the pasta but you own my heart"
- For a parent: "Mom turns 55 and still texts in all caps, love you anyway"
- For a coworker: "Happy birthday Jordan, our spreadsheet wizard, 29 and never missed a deadline"
- For a grandparent: "Grandpa Lou turns 80, still wins every card game at Sunday dinner"
One detail per song is plenty in 12 seconds. Pick the one that will make them laugh before the first chorus ends. If you write the line in Spanish, French or another language, the rap comes out in that language.
What you get
- Original lyrics. Written from your line, with the name and the detail you gave. No real songs, no famous rapper's voice.
- A beat and two AI voices. Two distinct rap voices trade the lines, so it sounds like a real duo.
- The two of you on stage. Both faces from your photos, rapping in sync with the vocals.
- A ready-to-send MP4. Vertical 9:16 by default for phones and stories; square 1:1 and widescreen 16:9 are there too.
Tips for a better birthday rap
- Use clear, front-facing photos. Good light and one face per photo give the cleanest lip-sync. The photos do not need to be taken together.
- Put the name first. Starting the line with their name makes sure it lands in the opening bars.
- Keep the teasing kind. A birthday rap is a gift. Save the sharper jokes for a funny birthday video roast.
- Only use photos of people who agreed. Yourself, friends and family are fine; celebrities are not.
- Make it a bit longer if you need to. You can go up to 15 seconds, or 30 seconds on the top model, for a longer verse.
