AI Rap Battle Generator
Two rivals, one mic, a night street corner. You bring the bars.
This AI rap battle generator turns two photos into a short battle video. Both rivals stand on an orange-lit street corner and perform to the audio you choose: a back-and-forth you record with a friend, or our original 15-second track. It doesn’t write bars for you. It puts your faces on the stage, ready to post in about five to ten minutes.
How an AI rap battle video works
You upload two photos, one per rival. The first becomes the performer on the left, the second the one on the right. The stage for this page is a night street corner washed in orange light, the closest thing to a cypher, and you can switch to any of the other five stages for the same price. The video model moves both mouths, heads and hands to the audio, so the energy of the battle comes from your recording. Both faces perform the whole clip together, which is why a recording where two voices trade lines feels the most like a real battle.
Record your battle bars on your phone
The best battles are recorded, not generated. Open the voice memo app, take turns with your friend, and keep it between 2 and 15 seconds; two short lines each is plenty. Hold the phone close, record somewhere quiet, and save it as MP3 or WAV under 3 MB. Then upload it in the generator in place of the default track. If you want to test the format first, the default 15-second rap works on every stage. Only use audio you have the rights to.
Make a rap battle video in three steps
Step one: add a clear, front-facing photo of each rival. Step two: keep the night street stage or pick another, upload your battle clip, and choose vertical 9:16 for TikTok and Reels or horizontal 16:9 for YouTube, at 5, 10 or 15 seconds. Step three: confirm the credits and generate. A 15-second Standard 2K battle costs 50 credits, and the finished MP4 comes with a download button and a share link.
Rap battle ideas that stay friendly
The funniest battles are about small stakes. Roommates arguing over whose turn it is to do the dishes. Two coworkers fighting over the office thermostat. Siblings settling who was the favorite. Two fans trash-talking before the big game. Best friends deciding who planned the better birthday. Keep the bars playful: this is a roast between people who like each other, not a way to go after someone.
Keep the rap battle fair
Only upload photos you have permission to use, and everyone pictured must be over 18. Don’t use a battle video to mislead, harass or impersonate anyone, and say it is AI-generated when you share it. Nudity and sexual content are banned. If a video uses your photo without your consent, email support@lobbyduo.com and we will take it down.

AI Rap Battle Generator FAQ
Can the AI write the battle lyrics?
No. LobbyDuo doesn’t write lyrics. Record your own bars and upload them as a 2–15 second MP3 or WAV clip, or use our original 15-second track.
Can each person rap their own lines?
Not separately. Both faces perform the same clip together, so record a back-and-forth where two voices trade lines and the video reads like a real exchange.
Which stage works best for a rap battle?
The night street corner is the default here because it feels like a cypher. The orange studio and the 1970s TV set work too, and every stage costs the same.
How long can a rap battle video be?
Up to 15 seconds, the limit of the video model. 5 and 10-second cuts cost fewer credits.
Can I put a celebrity in my rap battle?
No. Only upload photos you have permission to use, and never use a video to impersonate someone or make it look like they said something they didn’t.
How much does one rap duo video cost?
One 15-second video at Standard 2K costs 50 credits — the $9.99 pack. A 5-second cut costs 20 credits and a 10-second cut 35, and the lighter 768p quality costs 10, 15 and 20 for 5, 10 and 15 seconds. Every option is priced by duration and quality, and the pricing table lists the exact credits for each one currently offered.
