Description
RaceCut is an innovative platform that transforms songs into engaging marble-race videos, complete with AI-voiced marbles. Unlike other tools that provide a race and leave the music to the user, RaceCut prioritizes the audio, analyzing beats, sections, and choruses to build a race that perfectly aligns with the musical structure. This ensures that whoever leads the race is heard singing, with voices seamlessly handing off during overtakes.

The process is straightforward: users upload an MP3 or paste a cover link, then select a 15, 30, or 60-second section from the waveform. They can name their marbles, assign colors, and choose from a variety of AI voices. The platform offers several race formats, including "Marble Race" where each marble has a different AI voice, "Stage" for characters playing as a band, "Musical Path" where a ball bounces to the beat, "Loop Path" for endlessly looping videos, "Marble Solo" with singers along the trail, "Bounce Battles" for two fighters, and "Marble Drop" where a marble falls through the song.
RaceCut is designed for creators who post daily, focusing on the content creation workflow beyond just exporting. It includes features like "Batch" for generating multiple videos from one song or multiple songs from one course, "Autopilot" for scheduled daily posts, and a "Brand kit" for custom logos, colors, and intro/outro cards. Users can also create "Variants" of the same race with different hooks and thumbnails for A/B testing, and utilize "Direct posting" to connected TikTok, Shorts, and Reels accounts. An API with Zapier integration is available for agencies managing multiple channels.
The platform renders videos directly in the browser, eliminating upload queues and server-side processing for free renders. Paid plans leverage GPUs for faster batch rendering. The output is a 1080p MP4, ready for immediate posting to social media without additional editing. RaceCut also offers the flexibility to rig race outcomes, allowing users to choose winners while maintaining realistic physics. The first month is available for $5, followed by a $24.99/month subscription for unlimited AI-voiced races, up to 8 voices per race, and no watermarks.
