Drop a track or your Jammable covers, name the marbles, hit go. RaceCut builds the course, races it to the beat and hands you a TikTok-ready video. No Blender. No CapCut. No 3 a.m.
Free tier renders in your browser. Nothing to install.
Every other marble tool gives you a race and leaves the music to you. RaceCut listens first — beats, sections, the chorus — then builds a race that lands on them.
Upload an MP3, paste a link, or pull covers straight from your Jammable library. Cover Race takes several versions of one song — one per marble.
Fans, cartoons, countries, voices. Colours and avatars. Pick a course, a length (15/30/60 s or the whole song), and whether it's fair or rigged.
What you see in the browser is exactly what renders. Download 1080p with lyrics burned in, or send it straight to TikTok, Shorts and Reels.
Each marble is a different AI cover of the same song. Whoever leads is who you hear. Camera follows the leader — so does the audio.
Named marbles, one song, a winner reveal on the drop. Fair by seed, or rig it and let the comments fight.
Last place gets knocked out every section change. One survivor at the outro, on the beat.
“Top 10” countdowns — marbles finish in the order you set, one per lyric line.
Marbles hit bars that play the vocal line, transcribed from the stems. The satisfying one.
Persistent characters, standings and leaderboards across episodes — the reason people follow the channel.
RaceCut is built for people who post every day — the stuff that comes after “export” is the product.
One song × ten courses, or ten songs × one course. A week of content from one job.
“Every day at 6pm, race my newest covers and post to TikTok.” Set it, check the numbers.
Your logo, colours, intro/outro cards, fonts and hook-text presets on every export.
Same race, three hooks, three thumbnails. Post them all, keep the winner.
Connected TikTok, Shorts and Reels accounts. Schedule from RaceCut, no downloads.
For agencies running twenty faceless channels. Race spec in, MP4 URL out.
No. Upload any track or paste a link. Jammable just makes Cover Race one click instead of ten — your covers arrive with names and avatars attached.
Your call. Fair races are seeded and reproducible. Rigged races let you pick the winner or the whole finishing order, and RaceCut finds a physics run that produces it. Nothing is faked in post.
Yes — the same simulation and renderer run in your browser and on our render servers, frame for frame. Free renders happen on your device; paid plans render on GPUs so you can batch.
You're responsible for the audio you upload, same as any editor. Cleared library tracks and your own Jammable covers are the safest path, and direct posting follows each platform's commercial-music rules where they apply.
TikTok, YouTube Shorts and Instagram Reels at launch, scheduled from RaceCut. You can always just download the MP4.
We’re onboarding creators in small batches. Leave an email and tell us what you post — Jammable members go first.
