Upload a video, paste a script, or describe your idea — and ShortFast generates multiple unique versions of the same content. Each variation gets a different hook, pacing, editing style, visual treatment, and CTA. This lets you A/B test at scale to find which angle resonates best with your audience. Variations are unique enough to avoid duplicate content penalties on TikTok, Reels, and Shorts. Once you identify a winning variation, you can scale it further with additional tweaks. It turns one piece of content into an entire testing framework.
