Creative Multiplier

CreativeMultiplier

Record once. Multiply variations. Scale your creative testing.

Combine hooks, bodies, and CTAs to create videos ready to test, without editing each version by hand. Runs on your own machine — your footage never leaves it.

This tool runs locally on your computer (it needs ffmpeg and whisper.cpp installed) — there is no hosted version, so no footage is ever uploaded anywhere. See the install steps below.

Hooks, bodies, and CTAs go into the multiplier and become multiple video variations.
