Rap Duo AI — AI rap video generator from photos

Rap Duo AI is an AI rap video generator that turns photo references into a short performance by two people or pets. It creates the moving scene, beat and synthetic vocals together, with editable English lyrics and a downloadable MP4. It suits a birthday message, a friendly roast or a playful duet for social sharing.

What does Rap Duo AI actually do?

Think of it as putting two familiar faces into a miniature music video. Upload a portrait of each subject, choose what the rap is about, and the service generates them trading lines in a selected scene. You do not need to film yourself or record a vocal track. You can also provide one photograph containing exactly two subjects, although the official guidance favors separate portraits for resemblance.

The Orange Booth scene follows the two-rappers-and-a-microphone format associated with Hotel Lobby AI. The service says it generates a new performance and audio rather than supplying the original song or clip. Voices are synthetic, not recordings of the people pictured. Rap Duo AI is independent of ByteDance.

Make one clip, from photos to a reviewed MP4

1. Open the website in a phone or desktop browser and sign in with Google. If you arrive inside TikTok or Instagram, open the link in Safari or Chrome; the site warns that Google sign-in does not work in those in-app browsers.
2. Use Two photos for one clear subject on each side, or One photo of both for exactly two subjects side by side. The left subject raps first. Choose well-lit, front-facing photos without sunglasses or obscured faces; waist-up or full-body images are recommended.
3. Select a scene and theme, then optionally add names or customize lyrics. Review the verse before generating.
4. Choose the model, resolution, duration and aspect ratio. Check the displayed credit cost, confirm adult consent and photo rights, and select Generate video.
5. Play the result to check faces, lyrics, sound and synchronization before using Download MP4. Completed clips are also available in My videos. The official estimate is 2–4 minutes, rather than a guaranteed deadline.

Personalize the occasion, lyrics and stage

The five themes cover encouragement (Hype), friendly teasing (Roast), relationships (Love), birthdays and congratulations. Template verses can include two optional names. Write with AI accepts a short description, returns three lyric versions and lets you edit the lines; you may also write your own. A specific occasion or shared joke gives the verse something concrete to express.

Lyrics remain English, including when the description is written in another language. Names use Latin letters and the permitted punctuation. The lyric helper is labelled free, but generating the video costs credits. A five-second clip uses only the first line for each performer, so it will not deliver the full longer verse.

Scenes include Orange Booth, Neon Studio, Birthday Party, Front Seat and Halloween. Selecting Birthday switches the scene to Birthday Party, which you can change. Output choices are 5, 10 or 15 seconds; 480p or 720p; and vertical 9:16, landscape 16:9 or square 1:1. Vertical suits a short social clip; choose another shape when its destination calls for it.

Understand the cost before generating

The official USD price list, checked on October 1, 2026, offers 100 credits for $4.99 and 300 for $12.99, purchased without a subscription. Credits do not expire. No free video generations are offered.

Multiply duration by the selected rate: ten seconds with Mini at 480p costs 30 credits; ten seconds with Seedance 2.5 at 720p costs 160. Aspect ratio does not affect price. “Up to 20 videos” from the larger pack applies to five-second Mini clips at 480p, not every configuration. Failed generations return credits automatically. The refund policy allows a request within 14 days for a completely unused pack; credits spent on a completed video are not cash refundable.

Photo privacy and responsible sharing

The privacy policy says original photos are deleted within 24 hours and photos/videos are not used for model training or sold. Processing still involves providers: photo links and prompts go to the video provider, while AI descriptions and edited lyrics go to a text provider. Finished videos and account data remain until deletion is requested. Account access is restricted, with operator access possible for support or safety investigations.

Use photos you have rights to use, with explicit consent from every adult shown. Follow the homepage guidance excluding children, celebrities and public figures. Review and disclose the generated performance before sharing. The terms of service permit personal and social sharing under their conditions; they do not guarantee freedom from third-party rights. Results can vary in resemblance, so the tool is better suited to playful short messages than a guaranteed faithful recording or a long music production.

Frequently asked questions

Is Rap Duo AI free?

Video generation is paid. The free lyric-writing helper does not include a free video render, and there is no subscription requirement.

Can photos create the rap without recording anything?

Yes. Use two separate portraits or one image with exactly two subjects. The service generates the performance, beat and synthetic vocals from those references.

How long is the downloadable video?

Choose 5, 10 or 15 seconds and download an MP4 at 480p or 720p, in 9:16, 16:9 or 1:1. Generation usually takes 2–4 minutes according to the site.

Are uploaded photos kept permanently?

The policy says originals are deleted within 24 hours. Finished videos have a different retention rule: they remain with account data until you request deletion.
