Rap Duo AI

Rap Duo AI uses ByteDance Seedance video models — you choose between Seedance 2.0 Mini, Seedance 2.0 and Seedance 2.5 for each video — to generate video, music and synchronized vocals. Lyrics come from our own templates, or from a Google Gemini text model if you choose Write with AI. Rap Duo AI is an independent service, not an official ByteDance product.

Our Terms prohibit pornography / NSFW, violence / gore, hate speech, child-unsafe content / CSAM, unauthorized or deceptive deepfakes / impersonation, and copyright / trademark infringement. Every person shown must be 18 or older and consent. Use Report content or email hi@rapduoai.app with the video or job ID, your concern and supporting evidence. Reports and appeals are reviewed by the service operator.

Rap Duo AI is an online AI rap video generator. You upload two photos and it creates a short video where the two people (or pets) trade rap lines in an orange studio booth, with an original beat and lip-synced vocals.

Upload one photo for the left rapper and one for the right, pick a theme (Hype, Roast, Love, Birthday or Congrats), optionally add names or let AI write lyrics from a short description, and press Generate. An AI video model uses your photos as character references and generates the performance, beat and vocals together. The video is usually ready in 2–4 minutes.

No. Videos are paid for with credits: 100 credits cost $4.99 and 300 credits cost $12.99. A video costs credits per second depending on the AI model and quality — from 15 credits for the shortest, lowest-cost video, so the largest pack makes up to 20 videos. Every video is generated from scratch on a paid AI model, so we don't offer free generations — but you only pay for videos that succeed, because failed videos are refunded automatically.

No. Rap Duo AI works in any phone or desktop browser. If you opened this page inside TikTok or Instagram, open it in Safari or Chrome first, because Google sign-in doesn't work inside in-app browsers.

You choose 5, 10 or 15 seconds, vertical 9:16, wide 16:9 or square 1:1, and 480p or 720p. Generation usually takes 2–4 minutes. You can leave the page — finished videos are saved in My videos.

One clear, front-facing photo per person or animal, in even light, ideally waist-up or full body. Avoid sunglasses and dark or blurry photos. The two photos don't need to be taken together. You can also use one photo of the two of you — exactly two people or pets, side by side, both faces clear — though two separate photos usually look more like you.

Yes. Dogs, cats and other animals work well — use one clear photo per animal. Pets and other unexpected duos usually make the funniest videos.

Only use photos of adults who agreed to appear in the video — yourself, friends or family who said yes. Photos of celebrities, public figures or children are not allowed. You confirm this with a checkbox before every video.

Yes. Pick one of five themes and add two names for a ready-made verse, or choose Write with AI: describe the two of them and the occasion, and AI writes three versions to pick from. You can edit every line or write your own. Lines are kept short enough to fit the length you pick, and lyrics you write or edit are checked against our content standards. Review the generated result before sharing.

Yes. Pick a scene before you generate: the classic Orange Booth, Neon Studio, Birthday Party, Front Seat (the two of you rapping in a car) or Halloween. Every scene costs the same. Choosing the Birthday theme switches to the Birthday Party scene automatically, and you can change it back.

The lyrics are in English. Names use English (Latin) letters — accents like é are fine — plus numbers, spaces, apostrophes or hyphens. With Write with AI you can describe them in any language; the lyrics still come out in English.

No. Rap Duo AI doesn't use the original clip, the original song or any artist's likeness. It recreates the two-rappers-in-a-booth format with its own Orange Booth scene and an original beat and lyrics.

Pick vertical 9:16 for TikTok, Instagram Reels and YouTube Shorts, or wide and square for other platforms. Review the video, make sure you have the permissions needed to share it, follow the destination platform's rules and disclose that it is AI-generated. Generating new audio does not guarantee that an output is free of third-party rights.

Yes, you should. TikTok, Instagram and YouTube all ask creators to disclose realistic AI-generated content — use the platform's AI-generated label or toggle when you post.

If generation fails for any reason, the credits it used are returned to your balance automatically and you can try again. A different, clearer photo often fixes it.

Original photos are deleted automatically within 24 hours and are never used to train AI models. Only you can see your finished videos while signed in.

Credits never expire. Failed videos are refunded in credits automatically, and unused credit packs can be refunded within 14 days — see the refund policy.
