YouTube Shorts gets 70 billion daily views. The algorithm favors consistent posting — 3-5 Shorts per week is the minimum for growth. That's a lot of content to produce manually.
AI tools for Shorts fall into two categories: generators that create videos from scratch (text prompt → finished video) and repurposing tools that turn your existing long-form content into Shorts. The best choice depends on whether you're creating original content or extracting clips from what you already have.
We tested 10 tools specifically for YouTube Shorts creation and ranked them by output quality, speed, and how close each gets to a publishable Short without manual editing.
What YouTube Shorts Needs from AI Tools
YouTube Shorts has specific requirements that limit which tools work well:
- Vertical format (9:16) — Must be native, not cropped from horizontal
- Under 60 seconds — The hard cap (though YouTube is testing longer Shorts)
- Captions — 85% of mobile viewers watch without sound
- Hook in 1-3 seconds — Algorithm measures early drop-off aggressively
- Original audio — YouTube weights original voiceover higher than licensed music for Shorts shelf placement
