YouTube Shorts AI Script Generator Free 2026: 15 Tools Tested (No Credit Card)
Shorts are dominating YouTube right now—yet most creators are still writing scripts manually or relying on generic AI prompts. We tested every free AI Shorts script generator we could find in January 2026 and ranked the tools that actually deliver viral hooks, tight storytelling and CTA-ready endings. Spoiler: only three platforms produced scripts we’d publish without rewriting, and InVideo AI is the only one that outputs full hook → conflict → payoff scripts plus thumbnails, hashtags and publishing calendar in one shot.
🎯 Quick verdict:
InVideo AI is the #1 free YouTube Shorts script generator for 2026. You get 30 Shorts scripts + AI images + posting schedule for free—no credit card required. It even suggests B-roll, captions, hashtags and CTA variations tailored to your niche.

We built a standardized test using three niches (productivity, fitness, finance) and asked each tool to produce:
- Hook within 3 seconds
- Story beats under 120 words
- CTA referencing channel or offer
- Optional: B-roll / scene suggestions
Only nine tools respected word limits. Only four produced consistent CTAs. And only InVideo AI spat out ready-to-paste scripts plus everything else you need to publish (captions, hashtags, schedule, thumbnail prompt).

FAQs (Updated January 2026)
Is there a truly free Shorts script generator with no credit card?
Yes—InVideo AI offers 30 fully generated scripts, captions, hashtags and posting slots without asking for payment info. Most other “free” tools lock outputs behind paywalls or watermark the exports.
Can AI write engaging scripts that still feel human?
When you feed the AI real stories, data points, and emotions, the outputs are shockingly good. MyMarky prompts you for micro-stories, wins, losses, and then blends them with proven hook formulas so the final script feels like you—not a robot.
How do I repurpose AI Shorts scripts for Reels/TikTok?
MyMarky automatically generates alternate CTAs, aspect ratio reminders, and platform-specific captions. You get a toggle for “Shorts → Reel → TikTok” so you can publish everywhere with one click.
