ShortFast is an AI tool that creates both UGC AI videos and faceless videos for YouTube Shorts, TikTok & Reels. Generate UGC content with AI actors, scenes, and voices—or pair scripts with real stock footage for faceless channels. Then auto-publish daily on autopilot.
UGC AI videos are user-generated-content-style clips featuring realistic AI actors that look and sound human. You pick the actor, scene, and voice, write a script (or let AI write one), and ShortFast generates a ready-to-post UGC video in minutes. Perfect for product demos, brand ads, and scroll-stopping hooks.
Full creative control. Choose from a library of AI actors (male, female, different ages and looks), pick scenes (kitchen, outdoor, office, cafe, and more), select voices with different accents and tones, and customize the script. Mix and match to match your brand.
AI-generated visuals (like Sora or Runway) look fake, get flagged by platforms, and often fail monetization review. ShortFast uses real stock footage from premium libraries that passes all checks and looks professional—like content from real creators.
