BrainrotKit

BrainrotKit makes vertical short-form videos in the brainrot style: a script read by a generated voice over runner-game footage, with synced captions. You can paste a script, let AI write one to a target length, or convert a PDF into a video.

You choose background footage such as subway or temple runner clips, a voice, caption style, length and a 9:16, 1:1 or 16:9 format. The editor generates the voice first and lines up every caption and frame with the real audio before rendering.

Other modes include Italian Brainrot character videos, short AI motion clips, a brainrot voice generator and background removal. Credits are charged only when a render succeeds, failed steps are refunded, and finished videos export as MP4.
