AI Rap Video Maker
Turn Your Photo Into a Rap Battle

Yes. Making, previewing and exporting a 720p MP4 is completely free, with no signup, no credits and no daily limit. Free videos carry a small AIRapVideoK watermark. Optional paid upgrades (no watermark plus 1080p, a realistic human-motion version and a pro AI rap voice) are coming soon. You can leave your email in the tool to be notified, but you never have to pay to make and post a video.

No. Your photos and voice recordings are processed only inside your own browser. Face detection, animation, AI voice and video encoding all run on your device, and nothing is sent to our servers. When you close or refresh the tab, everything is gone. The only data we collect is anonymous usage statistics through Google Analytics (for example, "a video was exported") and, only if you choose to give it, your email for the launch notification. See our Privacy Policy.

1. Tap Export MP4 and wait for the progress bar to finish.
2. On a phone: tap Share to TikTok / Instagram and choose TikTok. If you don't see that button, tap Download MP4. On iPhone, open the file and choose Save Video so it goes to Photos.
3. On a computer: download the MP4 and upload it at tiktok.com/upload, or send it to your phone.
4. In TikTok, tap + → Upload, pick the video, add a caption like "Who won? 👇" and tag your friend.

The video is already 9:16 and about 21 seconds, so you don't need to crop or trim. If you exported "Vocals only", you can add a trending sound inside TikTok.

The most common causes, in order:

• Silent mode is on. Flip the ring/silent switch (or the Action button) so the phone isn't muted. Web audio on iPhone follows the silent switch.
• You're inside the TikTok or Instagram app browser. These in-app browsers block the microphone and audio export. Tap ··· → Open in browser to use Safari, then try again.
• The page hasn't been tapped yet. iOS only starts audio after a tap. Press ▶ Preview once before recording or exporting.
• The audio option is set to Silent. Under Export → Audio, choose Beat + vocals.
• The iOS version is old. Update to the latest iOS so Safari supports the video and audio encoders the tool needs.

If the downloaded MP4 plays silently in Files but has sound in Photos, that's an iOS preview quirk, and the video will have sound on TikTok.

Absolutely. Templates are just a starting point. Edit the seven lines in the Lyrics box: in Duo Battle the pattern is A, A, B, B, A, B and then a shared hook, and in Solo it's six verse lines plus a hook. Seven to ten words per line fits the beat best. Type {a} and {b} anywhere to insert the rappers' names automatically. Your lyrics appear as on-screen captions and are what the AI voice will rap if you choose it. Please keep it friendly and don't post harassment, hate speech or false claims about real people.

Only photos you own or have clear permission to use are allowed. That means you, or friends and family who have said yes. Photos of celebrities, public figures, minors without a guardian's consent, or anyone who hasn't agreed are prohibited by our Terms of Use, and that's why the tool asks you to confirm before exporting. Using someone's face without permission can also violate TikTok's rules and the law where you live.

• When the browser asks for microphone access, tap Allow. If you tapped Block, open your browser's site settings for airapvideok.com and switch the microphone to Allow, then reload.
• On iPhone: Settings → Safari → Microphone → Ask or Allow. On Android Chrome: tap the lock icon in the address bar → Permissions → Microphone.
• Close other apps that might be using the mic, such as calls, voice memos or other tabs.
• In-app browsers (TikTok, Instagram, Facebook, Snapchat) usually can't record. Open the page in Safari or Chrome instead.
• Still stuck? Choose AI rap voice, which needs no microphone.

Bluetooth headphones and some phones add a small delay. Use the Vocal sync slider under Rap Vocals: drag it right if your voice sounds late, left if it sounds early, then press Preview to check. Wired headphones or the phone speaker at low volume give the tightest timing. Wait for the one-bar intro before you start rapping, and follow the highlighted line.

Recent versions of Chrome, Edge and Safari on Windows, macOS, Android and iPhone/iPad. Firefox works for preview but may export more slowly or in a different format. Very old phones may struggle with the AI voice, which downloads a voice model the first time (tens of MB, cached afterwards). In-app browsers inside TikTok, Instagram, Facebook and Snapchat limit the microphone and downloads, so the tool shows a yellow banner telling you to open it in your normal browser.

• Keep the tab open and in the foreground while exporting. Phones pause background tabs.
• Close other heavy tabs and apps to free memory, then try again.
• Make sure you're not in an in-app browser or a private window with storage limits.
• Update your browser. Fast MP4 export uses WebCodecs, which is available in current Chrome, Edge and Safari.
• On older devices, export usually takes 20 to 60 seconds. That's normal, because the video is encoded on your device and not on a server.

Yes. JPG, PNG, WebP and iPhone HEIC/HEIF photos are supported, and HEIC is converted automatically in your browser. If a face isn't detected, try a brighter, front-facing photo where the face fills a good part of the frame without sunglasses or heavy shadows. You can always fine-tune the mouth sticker by dragging, resizing or rotating it.

No. AIRapVideoK is a website that works like an app. Open airapvideok.com, make your video and download it. There are no accounts, no passwords and no app store downloads. On a phone you can use "Add to Home Screen" if you want one-tap access.

Each video is about 21 seconds: a one-bar intro, six verse lines and a hook over a 100 BPM beat. The output is an MP4 file (H.264 video and AAC audio) in vertical 9:16, 720×1280 on the free tier. That fits TikTok, Instagram Reels, YouTube Shorts, Snapchat Spotlight and messaging apps without cropping.

Free exports include a small watermark. A no-watermark 1080p option is coming soon; tap No watermark + 1080p in the tool to join the waitlist. You're welcome to post your videos on personal and creator social accounts. For paid ads or commercial campaigns, you must have commercial rights to every face and every lyric in the video. Contact us if you need to use the built-in beat commercially.
