Choose one of six performance effects: Classic duet, Friendly rap battle, Birthday shout-out, Pet duet, Couple duet or Celebration duet. Add authorized photos and optionally supply the relationship, names, occasion and one personal detail. The effect supplies the directions; the finished words, sound and movement remain a new AI interpretation.

Make an AI rap video without writing a prompt
You can go straight from photos to a performance. RapDuo prepares the scene and performance directions when you choose an effect; the personal-details field can stay empty.
Choose the pair and effect
Upload two portraits or one clear photo together. Use the effect cards below to select a classic duet, friendly battle, birthday, pet, couple or celebration performance.
Leave the topic blank or make it personal
Leave personal details blank if you want a general performance. To make a gift or shared joke more specific, add only the name, occasion or familiar detail you want the rap to mention. You do not need camera directions or a finished lyric script.
Check the settings and generate
Choose the stage, length and frame, sign in and review the credit quote. Confirm Generate video, then listen to the completed result. The selected effect still works when you have supplied no topic.
Six effects for different duos and occasions
A performance effect changes the kind of original rap you are asking for. The stage changes its setting. These are separate choices, so a birthday performance can use the orange Hotel Lobby stage while a couple chooses Luxury Lobby. The cards select an effect in RapDuo; they do not provide a text recipe to copy.
Classic duet
A shared original performance for friends, siblings or teammates. A natural choice for a reunion, an introduction or a small story about the pair.
Use this ideaFriendly rap battle
Playful rivalry for two people with a harmless disagreement, competing hobbies or different habits. Keep the joke friendly and comfortable for both participants.
Use this ideaBirthday shout-out
A celebratory duet centered on a recipient and their occasion. The name, milestone and one recognizable personal detail make the greeting feel specific.
Use this ideaPet duet
A playful performance for two pets or a pet and its person, with the animals as the stars. Their names and everyday personalities give the duet a personal theme.
Use this ideaCouple duet
An affectionate performance for an anniversary, a shared trip or a relationship milestone. A shared habit or memory gives the occasion a familiar touch.
Use this ideaCelebration duet
An upbeat shared achievement for graduation, a reunion, a finished project or a team win. Choose one milestone that both performers can celebrate together.
Use this ideaAdd the information only you know
The optional personal-details field accepts up to 240 characters. Include only facts and humor the participants are happy to share. A short clip has limited room for several names, a long biography and multiple jokes, so keep one occasion and one detail central.
You do not need to describe lighting, a camera rig or a sequence of gestures. Choose the performance and stage in their controls. A personal detail can guide the generated verse; it is not a guarantee that every word will appear or that a particular voice will say it.
| Input to consider | Useful decision |
|---|---|
| Relationship | Friends, partners, siblings, teammates or pet and owner |
| Occasion | One birthday, anniversary, reunion or achievement |
| Names | The names or nicknames you want to check in the audio |
| Personal detail | One familiar habit, hobby, memory or harmless shared joke |
| Tone | Humor everyone shown is comfortable receiving and sharing |
Match the setting and language to the occasion
Hotel Lobby is the orange studio setting. Luxury Lobby has a warm hotel atmosphere; Studio Booth has a recording-studio look; Street Cypher has an urban setting. Pick the look you want rather than trying to redesign it through the personal-details field. Stage illustrations show visual concepts, while the published video case shows an actual output.
Rap supports English, Mandarin Chinese, Italian, Spanish, Brazilian Portuguese and French. The studio page language supplies the default; personal details written in another language guide the model toward that language. Choose a clear language expectation before generating. Names, accents and mixed-language lines still need checking in the final clip.
Keep the first configuration easy to judge
RapDuo has no personalized preview before paid generation. Save draft keeps the selected settings and personal details without uploading photos; select photos again when you resume. Public demonstrations are useful for judging the product style, but do not establish how a specific private pair will render.
Use a clear pair
Choose readable references and confirm both subjects in the previews. The Pet duet effect cannot restore an animal hidden in its source photo, and a longer description cannot recover missing face detail.
Choose the destination format
Use 9:16 for a vertical clip, 1:1 for square or 16:9 for landscape. Set the format before generating to reduce the need to crop one performer later.
Review the budget
The Single pack has 10 credits for $9.99. Standard 720p at 12 seconds uses 10 credits. Other settings change the cost. Review the live quote before confirming, and allow for another paid attempt only if your budget supports it.
Troubleshoot the result through the right input
| What missed the mark | What to review before another paid attempt |
|---|---|
| The mood does not suit the occasion | Check the selected performance and whether the personal detail fits it |
| The rap is too generic | Use one meaningful name, milestone or shared detail |
| The story is crowded | Remove extra occasions or unrelated details |
| A name sounds wrong | Check spelling and simplify the surrounding wording; exact pronunciation is not guaranteed |
| A face or pet marking changes | Replace the weaker photo rather than adding scene instructions |
| The clip has no audible sound | Test the downloaded MP4 and playback settings before deciding to generate again |
Questions before you create
Do I need to write Hotel Lobby AI prompts?
No. RapDuo prepares the performance directions automatically. Select the effect and stage, then add optional personal details. There is no full scene-prompt editor.
Do effects reproduce the original Hotel Lobby moves and song?
They guide a new original performance. RapDuo does not supply the original recording, clone artist voices or lock the choreography and words to the original video.
Can I leave the personal details blank?
Yes. The chosen effect still supplies a performance direction. Add names or an occasion only when you want to make the generated lyrics more personal.
Will the Birthday shout-out say the name exactly?
A supplied name is guidance for the new rap, without exact pronunciation or lyric guarantees. Listen to the finished result before sending the gift.
Does selecting an effect charge credits?
Choosing an effect or saving a draft does not generate a video. Review the credit quote and confirm Generate video to submit the paid render.
